No matter which air conditioner brand you may own, an ac capacitor is the most common part that fails. The worst part, is that most capacitors fail during the hottest or coldest time of the year, and the reason is not just a coincidence.

The following HVAC Guide will answer the following questions about air conditioner and heat pump capacitor’s…

• What is a capacitor?
• Why do capacitor’s fail?
• What happens when a capacitor fails?
• Bad AC capacitor symptoms.
• How much does a new capacitor cost?
• How often should I replace my capacitor?
• Can a homeowner DIY a capacitor replacement?

What is a AC Capacitor?

An ac capacitor is a small cylindrical, oval or square shaped device inside your heat pump or air conditioner that supplies or stores energy.  When your AC unit or Heat Pump turns on the capacitor’s job is to provide a bolt of electricity (between 300-600 volts) to either start or run the compressor, fan motor, or blower motor.

Air Conditioner Capacitors

There are two types of capacitors inside most air conditioner and heat pump systems, a run capacitor and a start capacitor. They both serve different purposes in your ac.  Some ac units have one, some have both and some even combine them into one.

Start Capacitor

Start Capacitor: to provide an initial bolt of electricity to get the compressor or fan motor to start working.  After the motor is spinning or cycling the start capacitor is not needed.

Run Capacitor

Run Capacitor: After the compressor and fan blade is started, the run capacitor takes over.  The run capacitor is to provide extra power for extended periods of time.

Why do AC Capacitors Fail?

Capacitor’s are a component of your air conditioner or heat pump system, eventually they will wear out and need replacement.  The most common reason for air conditioner capacitor failure is overheating.  Upon a visual examination the ac capacitor will be swollen and can even burst from the pressure, which is from overheating. This is a dead give away you have a bad capacitor.

Here are a few reasons why an ac capacitor can overheat.

1. Extended or Abnormal Run-Time: heat wave, or an improperly charged refrigerant level in your ac unit.
2. Compressor Age: Just like when people get older, a compressor requires more energy to get going as they age.  This can overwork a capacitor and can be predictor of a compressor failure coming soon.
3. Lightning or Power Surge:  Spikes or fluctuations in the power grid, which often time come from lightning strikes can cause major havoc to a capacitor.
4. Capacitor Age: The quality of capacitors manufactured these days just isn’t what it used to be.  Average life expectancy of a capacitor is only 8-12 years.

What Happens When a Capacitor Fails?

When a failure of a heat pump or air conditioner capacitor does happen, the first sign is that your home will be hotter or cooler than the temperature set by your thermostat. You may even notice that the fan is running but the air coming out of the vents is not cool.

If this happens, first check your breaker panel to see if a breaker has tripped, then take a walk outside to your condenser and see if it running. Pay particular attention to the fan blade, and if they are spinning.  If not chances are its a capacitor.

An AC condenser will produce two different sounds when operating normally.  You will hear the air of the fan blade, as well as the compressor.  If your fan blades are spinning but the unit sounds much quieter than normal, the compressor capacitor may be the culprit.

When a capacitor fails you will experience a breakdown of your heating or cooling system. Since a capacitor operates with over 300 volts, My HVAC Price recommends calling a local certified HVAC repair company.

Tips on how to choose the right HVAC Company, we wrote a guide to help you!

Bad AC Capacitor Symptoms

Here is a list of the type of symptoms you may face if your capacitor is going bad.

• In your breaker panel the air conditioning unit breaker has tripped.
• The fan on the condensing unit is not spinning.
• Your ac unit is very hot, this is due to the fan motor not running.
• Interment services, your air conditioner starts and stops often.
• The old capacitor is swollen or does not match the voltage rating.
• Your home is hot, or there is a problem when your air conditioner starts.

How Much Does a New Capacitor Cost?

The price of a capacitor (part only) for your air conditioning system or heat pump system can range between $9-$60 depending on the required specifications.  These prices are just for the capacitor part, and does not include any labor or additional parts that a repair guy or  HVAC technician would need to install.

On an average service call a company will arrive, perform a diagnosis on your system, replace the capacitor or parts inside the condensing unit (may have to run to supply store to get parts), then let the system run for a while to ensure it was just the capacitor which failed.  A failed fan motor or compressor can cause a capacitor to fail, the symptoms that you experience first is a bad capacitor.

This entire job can take anywhere between 1-3 hours. Prices can alter by your zip code and depending on whether the HVAC tech has the right type of capacitor or any other required parts on his truck.

The average all in price to replace an air conditioner or heat pump capacitor is between $280-$500. 

This may seem very extreme to a homeowner when you can find the same part online for just a few bucks, but having a technician trace if the capacitor failed on its own or as the result of an aging compressor is vital.

It may not be wise to replace a capacitor in a system whose compressor is about to fail, the capacitor can simply be the canary in the coal mine indicating a larger problem.  A professional HVAC tech can help you navigate this process.

How Often Should I Replace my Capacitor?

Capacitor’s in an air conditioner or heat pump can last up to 20 years, but the average life expectancy of a air conditioner capacitor is around 10 years.

If your system is over 10 years old and you have not replaced the capacitor it is wise to do this proactively to avoid any problems.  That way you will not have to deal with an outage, and as stated above most outages happen at the hottest or coolest times of the year.

One of the benefits to an on-going HVAC maintenance contract is for a technician can monitor the components and symptoms of a capacitor every year and look for changes.

Most of the time since the tech is already at your home, the cost to replace a capacitor is much less.  The added benefit of piece of mind is well worth it in my book.

Read our guide about HVAC maintenance to help homeowners understand the value.

Can a Homeowner DIY a Capacitor?

Capacitor replacement in your air conditioner should always be done by a certified HVAC or Electrical contractor.  This type of problem is not something that a homeowner should attempt to repair. Now, if you are a homeowner with those skills you can certainly handle the job, but if not DO NOT DIY.

Capacitors can deliver well over 400 volts and an improperly installed capacitor or type of part can lead to an electrical fire in your home.  At no time does My HVAC Price encourage any homeowner to DIY a air conditioner capacitor.

Maybe you’re comparing heating and cooling options? Perhaps your air conditioner and/or furnace has been around for a while? In any case, you’re wondering: how long does an HVAC system last?

On Average HVAC Systems Last Up To 15-20 Years.

Maybe you’re comparing heating and cooling options? Perhaps your air conditioner and/or furnace have been around for a while? In any case, you’re wondering: how long does an HVAC system last?

In truth, it depends. So, to help give you a better idea of an HVAC’s durability and lifespan, we’re going to cover the topic in more detail below. Let’s go!

How Long Does an HVAC System Last?

Generally speaking, HVAC systems last 15 to 20 years. Note, though, that this is not always the case. Some last shorter and some last longer.

There are a number of factors that affect the lifespan of an HVAC system. These factors include the following.

Maintenance

Regular maintenance can increase an HVAC system’s lifespan substantially. On the other hand, if you fail to maintain your HVAC system at all, its lifespan could become substantially reduced.

Regular maintenance for an HVAC system includes filter changes, cleanings, and repairs. The quicker you can rectify a problem, the less damage it will do, and the longer your HVAC system will last.

As such, it’s wise to schedule HVAC maintenance appointments on a yearly basis. Have an experienced HVAC specialist service your system and it will provide you with the maximum of its capabilities.

Environment

The environment in which an HVAC system exists can greatly affect its lifespan. For instance, if an AC condenser is perpetually being exposed to snow and cold, it’s bound to lose a few years of its functionality.

Or, if there’s a great deal of pet fur inundating your house, it’s bound to end up in your duct system, putting undue strain on your HVAC system. Unless the ducts are cleaned regularly, this can reduce the HVAC’s lifespan.

There’s also the heat and/or cold factor. If you live in an area with extreme temperatures, your air conditioner and/or furnace is going to have to work much harder than it would in an area with mild temperatures. This will cause it to give out prematurely.

HVAC Quality

Not all HVAC systems are created equal. Some are built to thrive through decades of consistent use. Others are shoddily constructed and will give out long before they should.

For this reason, when choosing an HVAC system, you need to make sure that it comes from a reputable company. Ensure that it’s under warranty and ensure that it has good reviews online.

Some of the best HVAC manufacturers include Rheem, Carrier, Lennox, and Trane. Note, though, that there are other reputable manufacturers out there.

Installation Quality

It’s not just the construction quality of your HVAC system that will affect its lifespan. The quality of its installation will affect its lifespan as well. If certain components aren’t installed correctly, they’ll incur unnecessary strain, causing the HVAC to die out before its time.

This is why, when installing an HVAC system, you need to choose a reputable installer. Find a contractor with positive reviews in your area and ensure that your system is set up correctly.

HVAC Unit Life Cycle By System

There are many different types of HVAC systems, all of which possess different lifespans. We’ll discuss the lifespans of the most common types below.

Central AC

Central AC units are used to cool entire homes. Generally speaking, they last between 15 and 20 years. Note, though, that their adjoining duct systems can last for hundreds of years.

Furnace

There are two types of furnaces: oil furnaces and electric furnaces. Whereas oil furnaces generally last between 15 and 20 years, electric furnaces generally last between 20 and 30 years.

Ductless Mini Split

Ductless mini-splits are wall-mounted units that are designed to serve single rooms. These electrically-powered units can last up to 20 years, and can sometimes even make it to 25.

Boiler

If you use a boiler for your heating, you can expect it to last between 10 and 15 years. Note, though, that when it comes to boilers, regular maintenance is an absolute necessity.

Heat Pump

Heat pumps are capable of producing both heat and cold, making them a great dual-force HVAC system. Generally speaking, heat pumps last for 15 years.

Signs You Need a New HVAC System

Because HVAC lifespan expectancies aren’t concrete, you need to keep an eye on your HVAC to determine whether it’s in need of a replacement. There are several signs you should look out for, including the following.

Inconsistent Temperatures from Room to Room

When a heater or air conditioner fires up, it should send identical temperatures to every room in the house. If it’s not, there’s a problem, either in the unit itself or in the adjoining duct system.

While a repair might help to keep the system going, a replacement might be needed instead.

Long Start-up Times

Generally speaking, when you make a temperature change on your thermostat, your HVAC should start within around 30 seconds. If it’s taking longer than this, your system is suffering some kind of impairment. Replacement might be needed.

Strange Noises

Are there strange noises coming from your HVAC system? If so, it requires immediate attention. Repair is almost certainly needed, and replacement might be as well.

Foul Smells

You’re also going to want to look out for foul smells. If there are bad odors coming from your HVAC (whether they be oil smells, mold smells, musty smells, or otherwise), your HVAC needs professional attention. Though repair might be able to prolong the HVAC’s life, it might instead need to be replaced.

When you have a problem with your HVAC system it can put a stop to your life in a hurry.  While some of these common HVAC problems are a quick DIY homeowner fix, others require a professional to repair.

A large majority of these problems are simply due to a lack of maintenance, and if left unattended for too long can add up to a wallet busting bill from your local repair man.  We suggest that all homeowners keep a routine schedule when it comes to HVAC maintenance, which at a minimum should be annually.

GET ANSWERS TO THE 7 MOST COMMON HVAC PROBLEMS

1. LACK OF MAINTENANCE

Regularly scheduled maintenance for your heating and cooling system by a licensed and certified HVAC contractor is a MUST to keep your system running without breakdowns.  Many of the most common furnace problems can be avoided during an annual maintenance visit.

Technicians will check many of the following items on a furnace maintenance visit:

• Inspect the flue piping for any damage, birds nests or any other restrictions that can cause a back-up of carbon monoxide inside the home.
• Inspect all of the high limit switches and roll-out switches that shut down a furnace if there is an emergency.
• Inspect the heat exchanger inside of the furnace to make sure no breeches have developed over the last season.

Not only are technicians checking for possible future mechanical failure points, but the technician is looking to protect your family from possible dangers with carbon monoxide.

Your heating and cooling system is a very large investment, and routine maintenance can help protect that investment from small problems leading to a large expense.

2. DIRTY AIR FILTERS

Replacing your air filter inside your heating and cooling system is the easiest, but most forgotten way to avoid most of the common HVAC problems.  Just like a car requires an oil change every 5,000 miles, your HVAC system requires a new air filter to operate correctly.

When an air filter gets dirty it restricts the amount of air flow thru the appliance.  This can cause overheating problems, extra stress on the blower motor and even causes your energy bill to rise.

We suggest to use a standard 1″ air filter that is pleated and has a firm border.  Some of the high efficiency air filters from 3m are great at catching allergens such as pet dander, mold and dust.  Pay particular attention to these 3m filters as they tend to get clogged quicker since they catch more particles.

3. PILOT OR IGNITION PROBLEMS

Ignition problems can come from a number of causes.  A burned out thermocouple or hot surface ignitor, dirty flame sensor or a blown out pilot can cause a furnace to lockout on safety and not heat your home.

Sometimes the first step is to simply turn the furnace power off and let the board reset itself.  Then turn the furnace back on and see if the appliance lights.  If the furnace does not come back on call an HVAC technician as this type for problem is best solved by a certified professional.

Performing a homeowner DIY fix on natural gas and/or high voltage can be a very risky and dangerous task.

4. THERMOSTAT PROBLEMS

There are hundreds of different models of thermostats on the market today, but most fall into the category of programable or non-programable.

Most of the modern thermostats operate partly or primarily by batteries.  A dead giveaway that the batteries maybe dead is if the screen is very dim, or even blank.  Check to see if your thermostats has batteries and more importantly think about the last time you replaced them. This may do the trick!

Other thermostat problems that could be the culprit is the scheduling/timing is off.  Check the settings to see if the schedule has called for the thermostat to turn off the appliance.  You may have to google the model for an installers guide if you do not have the brochure.

After you have checked these two common thermostat problems and you are still unable to get the system functioning reach out to a professional HVAC tech for help.

5. MACHINE WEAR AND TEAR

Inside a heating and cooling system there are many moving mechanical parts, that over time can begin to wear out.  Belts and bearings are the most common parts that wear out if not properly tightened and lubricated during routine maintenance.

Symptoms of mechanical  wear and tear can easily be prevented and/or repaired proactively during regular maintenance visits.  Mechanical wear and tear always seems to show its ugly head during the hottest or coolest time of year when you HVAC system is operating under full load.

6. UNUSUAL FURNACE NOISES

Furnaces naturally make some noise while they operate, but when you hear noises that are out of the normal it’s cause for concern and requires attention.  Squealing noise is the most common furnace noise and is caused by a bearing in the blower motor that is failing.  This sound will not go away and a new blower motor is required.  A booming or explosion noise is the most dangerous and is cause of immediate attention.  The boom can come from delayed ignition of natural gas, which sometimes is caused by a gas valve or combustion air problem.

If you are hearing booming noises coming from your furnace turn off the appliance immediately and call an HVAC professional.

7. TRIPPED BREAKER OR BLOWN FUSES

The most common reason that a breaker trips on a furnace is due to a blower motor which is over working.  This can be an easy DIY fix if your filter is dirty.  The dirty filter is restricting the airflow and is causing the blower to over amp.  Simply change the filter in the furnace, then switch the breaker back on and most of the time this solves the problem.

Another reason that your breaker or fuse has been tripped is a power surge.  This is especially true during the summer time when a thunderstorm has gone thru.  The electrical disturbance can cause either a spike or drop in voltage that results in a breaker tripping or fuse blowing.

The worst senerio is when your breaker trips on your air conditioner.  This almost always is a sign of a compressor failure or burn-out.  If this is the case I am sorry to tell you but you are in the market for a new air conditioner.  The breaker tripping was merely a result of a catastrophic failure of the compressor and it caused a dead short.

Best way to fix your common HVAC problems

Without a doubt the best way to fix your common HVAC problems is simply to hire a professional.  Although this may cost you a few hundred dollars, the repair will come with some sort of guarantee.  We wrote an article about what to look for in hiring a HVAC Contractor and you can read it here.

When cold weather hits, the last thing you want to come home to is your central heat not working. Winter is a beautiful but often dangerous season. In fact, this biting season accounts for 20 times the amount of deaths than heat.

As the last remnants of summer dissipate, it’s important to prepare for the cold and snow-dusted days ahead. That includes knowing the most common signs of heat pump problems in cold weather.

Read on to find out what kind of problems happen most often with central heating, as well as what you can do to fix it.

Help! Why is My Central Heat Not Working?

Whether you own a Rheem, Goodman, Trane, or some other brand of central heating, these 10 common heating problems can happen in all of them.

1. Your Heating Isn’t Consistent Throughout Every Room

Does it feel like the temperature in your home varies from room-to-room? If so, this isn’t normal. While some may blame an old house for spotty heating, the truth is that it could be a sign of an issue that needs attention.

There are a couple different reasons why a home might not be heating its rooms evenly, including:

• Dirty Air Filters
• Air Duct Problems
• Closed Vents Blocking Airflow
• Open or Poorly Insulated Windows Impacting the Air Temperature
• Your System is Unbalanced

How to Balance Out Your Home

Some of these are extremely easy to fix. Start by checking your air filters and vents. Dirty air filters restrict airflow, which not only impacts the temperature in your room but also makes your system work harder.

You’ll want to make sure you change your filters every one to three months, depending on how quickly they get dirty. Also, you should make it a point to adjust the vents in each room so they welcome the right amount of air.

If the vents are closed in certain rooms, the heat in your home will bypass it and move on to the next open vent.

Next, check your windows. Make sure they aren’t just closed but also well-insulated. There are several ways you can test your windows for air leaks. Even if they are subtle, they can cause drafts and cold spots in the home as well as elevate your heating bill.

If none of these steps work, you may have a much larger problem on your hands. Your air ducts may have leaks, kinks, or other issues that are disrupting the airflow throughout the house or you may just need your system balanced.

Air balancing is a service that adjusts how much cool air or heat each room in the home receives. This may involve adjusting how your air ducts are installed or using dampers to tweak how airflow travels through your home.

Either way, these last two challenges should be tackled by an HVAC professional.

2. The Heating System Doesn’t Shut Off

Your thermostat and your heating system should work hand-in-hand. If you find your heater keeps blowing even when it shouldn’t, it’s time to start investigating for a problem.

Start by taking a look at your thermostat’s settings. On a good day, it may just be that your system is set at “On” instead of “Auto”. If your system is simply set on “On”, it will continue to run until you change it.

However, the “Auto” setting will adjust how your heating and air runs based on the set temperature. If you have to transition your thermostat to this setting, give your system time to adjust. It should kick on or off from the moment you set it as it works to synchronize your home environment with the thermostat’s setting.

Okay, great! Easy enough. But what if this doesn’t solve the problem?

Exploring Beyond Your Settings

This could either be a sign of a thermostat or blower issue. If it’s the thermostat, you may need to rewire or replace it. First, check to make sure your thermostat’s wiring is plugged in.

Next, reset it to the manufacturer’s settings, then give it time to run. If this fixes the problem, you’re set! If not, you may need to replace your thermostat.

The other cause could be that you need a blower repair or replacement. Either way, we recommend consulting a heating repair specialist.

3. All Your Heater Will Produce is Cold Air

If your heater fails to live up to its name by producing cold air instead of warm, don’t panic! Before you pick up the phone and start dialing HVAC companies, there may be an easy fix.

Check your thermostat once again to make sure it’s set to “Auto”. While some homeowners think “Fan On” is a good setting, it doesn’t produce heated air. If the setting is right, move on to your air filters.

Are they clean? If not, replace your filters so your heating system can run efficiently.

Next, take a peek at your pilot light on your heating system. This should light up when your heat is on. If it doesn’t, you may have the gas-related issue. Call an HVAC technician, just to be safe.

It may be that your gas valve is off your system is out of oil, gas, or an electric source.

Leaky ducts can also be a culprit. Again, you’ll want to consult a professional for issues like these.

4. Your Heater Won’t Light or Remain Lit

Newer heating systems rely on electricity instead of gas or oil. Because of this, a lot of the components are digitally controlled. If the light on your heater isn’t lighting up or turns on and off intermittently, this could be a sign of a dirty or broken sensor.

If cleaning the sensor doesn’t work, have it replaced.

5. The Thermostat Isn’t Working Properly

Not all heating system problems involve the unit itself. Sometimes the problem lies solely in your thermostat. Like your unit, your system’s controls sometimes need repair or replacement.

Signs of thermostat problems include:

• Issues Setting or Adjusting Your Home’s Temperature
• Your System Won’t Respond to Thermostat Settings
• Your Thermostat Loses Power
• The Heat in Your Home is Uneven

If you troubleshoot your thermostat and reset it to the manufacturer’s setting but problems persist, try checking the circuit or replacing the batteries. If this doesn’t work, it may be time to call your local HVAC specialist.

6. Mold is Growing in Your Heating System

Mold loves a moist environment. If your home or climate causes moisture to build up inside your ducts or system, it can lead to mold growth. This is never a problem you should let go untreated.

Letting mold grow in your system or ductwork can lead to poor air quality and even respiratory issues. If you suspect mold is growing in your HVAC system, have a technician come by to inspect and clean it.

7. You Smell Something Burning When the Heat is On

If your heater produces a burning smell the first time it kicks on, it may simply be burning away the dust and debris that accumulates during its dormant months.

However, if the smell doesn’t go away you probably have a much bigger problem on your hands. Step one is to shut off your system immediately. Unplug it, then inspect the system.

Clean any dust and dirt you may find and check your air filters to ensure they are clean as well. Afterwards, test your system again. If the smell persists, shut it down and contact an HVAC company immediately.

8. The Heating System Fan Stops Working

If an external source causes your heating fan to stop working, you may be able to fix it yourself. Start with the usual routine of checking your thermostat settings, your air filters, and your circuit breaker.

Be careful when testing the circuit breaker. Avoid flipping them on and off in succession, as this elevates your risk of starting an electrical fire.

If none of these troubleshooting steps remedies the problem, then you likely need repair work.

9. Lack of Maintenance Catches Up with Your System

Like your car, your AC needs regular maintenance. After all, it runs day and night, seven days a week, and 365 days a year. Make it a point to schedule regular maintenance for your system.

It’s like a tune-up. A technician will come out to your home to clean your system, check its components, and make sure everything is running efficiently. It’s also a great way to prevent major repair problems, as he or she will replace any pieces showing signs of wear and tear.

10. You Notice Your Energy Bill is Getting More Expensive

Is your energy bill on the rise? While certain seasons require our HVAC system to work harder than others, any anomalies in the usual trend could be a sign of a problem.

First, check your air filters and your breaker. Make sure there is nothing obstructing the airflow and your breaker wasn’t tripped. If both of these are fine, you may have a refrigerant leak or a problem with one of the system’s components.

Set up a maintenance call with a certified HVAC technician who can inspect your system’s performance.

When Repair is Not an Option, Buy Smart

If you’ve diagnosed the problem and it’s clear your central heat not working is the results of something that can’t be fixed, then make it a point to shop smart and contact a certified HVAC professional. Read our HVAC guide on how to choose the right HVAC contractor.

According to research, you’re not the only one who hates their electric bill. Over 30% of US homeowners have trouble paying their monthly bills. 

Does your home run on an outdated, standard thermostat? If so, it could be costing you money without you even knowing it. Traditional thermostats don’t have the modern capabilities to know the most cost-efficient temperature. This means your HVAC system is constantly running at settings that take money out of your pocket. 

It might be time to consider upgrading to a smart thermostat. Investing in this change can save you up to 20% on your energy bill without adding any maintenance stress. 

Are you wondering how smart thermostats work and if they’re right for you? Read this homeowner guide to learn more about how investing in a smart thermostat can save you time and money. 

Smart Thermostats: What Are They and How Do They Work?

Before we go into the specs for smart thermostats, let’s talk about traditional thermostats first. If you don’t live in a newer home that’s upgraded to “smart status,” then this is the system that you’re probably familiar with. 

Regular thermostats are basic control panels that let you adjust the heating and air conditioning system in your home. When you want your home at a certain temperature, you adjust the panel and let the system do its thing. When you want it to stop or if the temperature is not right for you, you have to change it again. 

Some of you might have a programmable thermostat, which is the next step up. These have buttons on the panel that allow you to set a timer so that it kicks in on a schedule. Although these have more capabilities than standard models, their complicated design frustrates homeowners. In the end, most programmable thermostats become regular thermostats. 

If your home has anything less than today’s smart thermostats, you’re probably losing money with high electric bills. Upgrading to a smart thermostat might be the best option for you. 

Smart Thermostats Are Different

Smart thermostats are special because they learn from your behavior. They’re also in-tune with the rest of the house. You can control the settings remotely, and it gives you information like real-time energy consumption. 

What does this mean, exactly? Maybe you’re leaving the house for a long work day and don’t want the heating system to run all day. With a smart thermostat, you can program it to kick in just in time to have the house nice and cozy when you get home. Not too soon and not too late. 

What makes this possible is the thermostat’s ability to learn how long it takes to make the temperature change you requested. You can see how effective your system is and you won’t waste money cranking up the heat all day. 

Most smart thermostats have a Wi-Fi chip that connects to the Internet. This gives you the freedom to control its settings through a smartphone app.

You can even connect some smart thermostats to your smart assistants like Amazon Alexa or Google Home. This lets you control your thermostat just by using your voice. 

“Teach” and Control Your HVAC System

How do you “teach” your behaviors to your smart thermostat? The process is easy.

When it’s first installed, you’ll need to make manual adjustments for the first week. This normally means you’ll change it when waking, leaving the house, coming home, and going to bed.

In time, the thermostat learns those behaviors and can make those adjustments on its own. It does this through algorithms that process the data it receives. The more information it learns, the more adaptable it gets. 

Soon, it will know the most cost-efficient settings for when outside temperatures are severe. It will know when to turn the AC on in the summer, and when to crank up the heat in winter. 

Why Traditional Systems Are Costing You

Unlike smart thermostats, traditional thermostats give you less control. You have to make manual adjustments at home every time the temperature changes or the weather shifts. If you forget to turn it off when you leave for work, it runs all day and doesn’t stop. 

They Need to Be Micro-Managed

Unless you’re 100% on top of things, there are going to be times when you forget to adjust the thermostat. This means you lose money because it’s running all day when it doesn’t need to be. 

You might also make the mistake of cranking the heat up to warm your house as fast as possible. This technique sounds good in theory, but it’s actually costing you extra money. 

They Aren’t Accurate

Most traditional thermostats aren’t precise in their readings. This means you often have to fiddle with it to get the temperature right. Every time it turns off or starts back up, it uses an extra boost of energy which takes money right out of your pocket. 

They Don’t Care about Your Energy Bill

When your outrageous energy bill is on your mind, it can sometimes feel like your standard thermostat is working against you. It won’t tell you how long it takes to warm up or cool down the house. It keeps running even when no one is home. When you don’t know the most cost-efficient setting for your thermostat, it means you pay extra money every month. 

How a Smart Thermostat Can Save You Money

You can expect to save 10%-20% on your energy bill when you install a smart thermostat instead of a traditional system. This is because smart thermostats give you the capability to control your home’s HVAC system in a cost-efficient way. 

Types of Smart Thermostats

As we enter the age of “smart homes,” the market for smart home devices explodes with options. Today, there are various types of smart thermostats available for you to choose from. 

The Learning Type

You have plenty of choices if you’re looking for a smart thermostat that can learn from your behavior and the environment. These types of thermostats will sense when someone’s home, if they’ve turned on the oven, or if the air is humid that day. Once it picks up on this data it can adjust itself accordingly. 

The Connected Type

A bonus to some smart thermostat models is that they offer remote access from your phone or connected device. This means you can make adjustments from literally anywhere. Connected thermostats also let you access data right from your phone so you always know what’s happening. 

The Type That Does Both

Of course, many popular brands will offer both learning abilities and connectivity. These types of smart thermostats will cost the most but give you all the capabilities. 

What to Consider When Shopping

Before you decide to move ahead with a new smart thermostat, there are some things you need to consider. These are important checkpoints you should run through to make sure a smart thermostat is the best for your home. 

Do You Use a Smartphone?

Smart thermostat features are enjoyed through a connected smartphone or device. If you still go old-school with a flip phone, then you might consider a standard programmable thermostat (or upgrading your phone). 

Are You Willing to Invest?

Upgrading to a smart thermostat will take a small investment. You’ll need to pay both for the device itself and for professional installation. The investment is worth it in the long run, but it’s a price you’ll need to consider before moving ahead. 

Are You Smart-Home Savvy?

A smart thermostat is more complicated than a standard thermostat. According to one study, 89% of homeowners struggle with programming their thermostat.

You’ll need to learn the program settings, buttons, and connectivity to be able to fully use a smart thermostat. You’ll also need to be comfortable with Wi-Fi. 

Do you already have a programmable thermostat that you hate? When programmable thermostats came out twenty years ago, their clunky design became frustrating.

The good news is that smart thermostats are designed to be more user-friendly than programmable thermostats. Today’s new models feature large screens that only require a few simple taps to make changes. 

Will It Work with Your Home’s HVAC System?

Before you purchase a smart thermostat, you need to make sure it’s compatible with your current HVAC system. Many of today’s gas furnaces and heat pumps have compatibility checkers that you can use online. You can also speak with an HVAC technician about how a smart thermostat will work with your system. 

Cool Down, Save Up

Is it time to get smart with your thermostat? Upgrading to a smart thermostat can save you money and add comfort to your home. With smart capabilities like Wi-Fi connectivity, it’s easier than ever to adjust your home’s temperature from your phone. 

Do you need to update your HVAC system before ordering a smart thermostat?  We made a Homeowners HVAC Guide, which can help answer any questions you may encounter along your journey. 

There is little worse than having your furnace die in the midst of winter. To make matters worse, it always seems to happen during an unusual cold snap. Plus, HVAC professionals are in the midst of their busy season, making it difficult to schedule a service call quickly.

In addition, if your furnace is beyond repair, you have to make a decision about buying a new one faster than you’d like. Every hour you spend deliberating over which furnace to buy and waiting to have it installed is an hour that your house is cold and uncomfortable.

You might end up spending more than you planned, or maybe you don’t even have enough in your emergency savings to cover the cost. After all, the average cost to buy and install a new furnace hovers around $4,000!

However, there are a few things you can watch out for to avoid this scenario altogether. Keep your eyes and ears open for these 10 telltale signs you need a new furnace.

1. The Age of Your Furnace

Unfortunately, as with most things, furnaces don’t last forever. The average life of a furnace is between 15-20 years. 

With proper maintenance, you may be able to stretch that out a bit. But the opposite is also true. If you don’t keep up on things the way you should your furnace could go out even sooner. 

If your furnace is getting old, at the very least you should have a professional inspect and maintain it before winter starts. Otherwise, you could end up being pretty chilly while you’re waiting to get a new furnace installed. 

2. Frequent Repairs

Your furnace needs a repair…again. You might figure that a minor repair isn’t a reason to get a new furnace. After all, for a quick and simple fix, why bother buying a whole new furnace?

But when was the last time you had to call for repairs? In general, furnaces hold up pretty well until their last couple of years of life.

If you’re having to call for two or three repairs in a year, even if they’re minor, this is a warning sign that your furnace is about to go out for good. It may be better to not waste money on repairs that will only keep your furnace limping along for another year or two.

3. Expensive Repair

Alternatively, even if you have only one repair, consider the cost and the age of your furnace. What if your furnace is already reaching the end of its normal lifespan and a repair will cost approximately 50% or more than the cost of a new one?

It doesn’t make sense to invest in repairing a furnace that won’t last much longer anyway. You might as well put that money towards a new furnace and have a better chance of getting your money’s worth out of it.

4. Changes in Your Heating Bill

Several factors can affect changes in your heating bill. Your system will run more and use more energy during a winter that’s colder than usual. Also, fluctuations in the price of gas or electricity (depending on the type of furnace you have) can affect your bill.

But what if you’re noticing changes in your bill that you can’t explain by external factors like these?

It could very well be that your furnace is going out. Maybe there aren’t other obvious signs yet, but your furnace is working harder and using up more fuel for the same amount of heating. 

5. The Thermostat Doesn’t Seem to Work

Do you have trouble finding the sweet spot for heating your home? You should be able to set and forget about your thermostat. This is especially true if you have a smart thermostat. 

But do you find that one day 72 degrees feels nice and the next it feels too cold? There could be a simple problem with your thermostat…or your furnace could be going out. To find out, have a professional examine your thermostat and furnace. 

6. Your Home Heats Unevenly

In addition, you may find that when you set your thermostat, some rooms get hotter than others. If your thermostat, sensors, and furnace are working, the whole house should warm to the same temperature. 

If that’s not the case, something could be wrong with either the thermostat or your furnace. Again, calling a professional is the best way to figure out what’s wrong and make the right choice about repairs or replacement.

7. More Dust Than Normal

Dusting isn’t high on anyone’s list of favorite chores. But even if you hate it enough to scour the internet for dusting hacks to speed up the process, dusting is a necessary part of life.

It could also be a sign that your furnace is going out. 

The first thing to check, however, is the filter. Furnaces pull air from outside, heat it, and then distribute it throughout your home. Thus, they use a filter to keep dust from ending up also distributed throughout your home. 

The outside air isn’t the only place your system can get dust from. Dust can also accumulate in your ductwork to the point that when you turn the system on a puff of dust comes out of the heat registers.

These are all signs that your system is not performing to the capacity that it should be. Time to get a professional’s opinion!  

8. Hearing Random Noises

No heating system will ever be completely silent. It’s a mechanical system so you’ll hear the machinery working and fans blowing, etc. 

However, what if you start to notice strange rattling, banging, buzzing, humming or popping noises? If your furnace starts making noises that it didn’t make before, that’s a sure sign that something is amiss.

These noises can be an indication of leaks, cracks or other structural issues with your furnace. Of course, calling a professional is the best way to figure out how serious the problem is.

9. Yellow Flames on a Gas Furnace

The pilot light in your gas furnace should be blue, but you may notice that it turns yellow. This could be something as minor as a problem with the fuel not burning efficiently.

A yellow flame could also be a sign of a far more serious problem. Your furnace may be producing carbon monoxide gas that is getting into your home’s air supply. 

Every year around 20,000 Americans go to the emergency room with carbon monoxide gas poisoning. Around 400 people die. 

Carbon monoxide is an odorless, tasteless, colorless gas produced in the fumes when you burn gas fuels. However, this dangerous gas can kill an individual who breathes too much of it.

The fact that it is virtually undetectable makes carbon dioxide even more dangerous. In fact, a good way to notice carbon monoxide gas is by paying attention to how you feel.

If you start to notice flu-like symptoms like nausea, headache, and dizziness, watch out. Carbon monoxide fumes can make you pass out and kill you as you continue to breathe them in.

Other signs to watch for are

• soot around the furnace
• water leaking from the chimney base, vent pipe, or flue
• excess condensation on the walls or windows
• rust on the pipes or pipe connections 

If you notice any of these symptoms or problems, don’t mess around. Open some windows, shut down your furnace and call a technician. 

10. Your Furnace Goes Kaput

Last, but not least, the most obvious sign that you need a new furnace is that your current one goes kaput. If your furnace stops working and the technician says there isn’t a viable option for fixing it, it’s time to start shopping. 

If it’s the middle of winter, you’d better start shopping right away.

Buying a New Furnace

Buying a new furnace sounds like an overwhelming task. That’s why some people might put it off even if they notice any of the signs that we’ve talked about. But that’s a terrible strategy.

Rather than wait until you have to buy a new furnace under a time crunch, take the chance to pick out the perfect furnace for your home–and your budget.

The process doesn’t have to be as scary as you think. In fact, we take all the work out of it for you. MyHVACPrice has extensive furnace reviews and heat pump reviews to help you find the perfect  HVAC system for your home. 

You rely on your home’s HVAC system to keep your space comfortable, no matter what season it is. But the more you use it, the more often you’ll need to schedule maintenance and repairs.

Some repairs you can handle on your own. But others are best left to the professionals. Otherwise, you risk damaging the system and increasing repair costs in the future.

There’s more to hiring a trustworthy HVAC contractor than simply calling the first company you find. You need to find someone you can trust. But where do you start?

In this guide, we’ll go over the most important qualities to look for when hiring a trustworthy HVAC specialist.

Experience

No two HVAC systems are alike. That means that a few qualities are as important as experience.

Look for a contractor that’s worked in the industry for at least a few years. This doesn’t mean you need to hire a company that’s been around for the last decade.

Younger technicians are a great choice as long as they’ve apprenticed an experienced contractor.

When calling to schedule an appointment, don’t be afraid to ask about the technician’s experience. If the person on the phone can’t or won’t answer you, keep searching.

Most contractor will happily discuss their experience with you. Keep in mind that an inexperienced technician working for an established company is worth considering. Everyone has to start somewhere and they’ll have the knowledge and experience of older technicians to draw from.

License and Insurance

Every contractor should have a valid business license and insurance in place before ever working on your home.

The license is issued by the state and ensures that they have a minimum amount of experience in the industry. The state tests candidates before they receive their license.

This helps create a standard of service across all providers and keeps your home safer from damage. Without a license, there’s no guarantee that the contractor is trustworthy.

Besides the business license, the technician should have current liability insurance in place. Think of it this way: you’re hiring someone to fix your HVAC system. If they damage it, they should be responsible for the cost of repairs.

Without insurance, this may not be the case. Worse, you’ll also be responsible for their injuries if they get hurt on the job!

Take the time to ask for proof of license and insurance before you accept a contractor’s estimate.

A Great Reputation

An experienced HVAC contractor will have tons of previous clients. When they’re reliable and trustworthy, those clients will not have reason to file complaints against the company.

Take a few moments to research each company you’re considering working with. The Better Business Bureau is a great place to start.

If the online reviews and Better Business Bureau ratings are all good, you’re safe working with them. If they’re bad or you see a lot of inconsistency in ratings, keep looking.

Great References

Online reviews are a great place to start, but they won’t tell you what you can expect in the long-run after hiring the contractor. Most reviews are given immediately after service, not several months after the work is done.

The best way to find out if a contractor is worth hiring is to speak with their previous customers. Ask each company for references and follow up on those references.

This will give you an honest look at what you can expect from the contractor. If the majority of clients are still happy with the work they did, you can expect the same quality service.

If they’re not or they had to fight to get mistakes repaired, keep looking.

Versatile Background

The HVAC industry is constantly changing and evolving. This means that not all systems are the same. And some, especially older models require different types of service.

Make sure your HVAC contractor can handle the types of units you have at home. If you don’t know what you have off the top of your head, go inspect your unit. Most air conditioners and furnaces have the brand printed on the outside of the unit.

When scheduling an appointment, ask if the technician is familiar with that particular brand. If not, don’t panic. Schedule the estimate and let them inspect the system.

Great technicians will be able to service older or obscure brands just as effectively as newer models. They take the time to learn new technology and aren’t stuck doing things the way it was done 20 years ago.  

As an added bonus, if they’re not comfortable working on your unit for any reason, they’ll probably know someone who is.

Free Estimates for Service and Installation

No good contractor will charge you for service or installation estimates. It’s just part of the process. After all, they want you to make the best decision for your budget.

Before you schedule the appointment, ask what they charge for estimates. If they quote you a price, walk away. These contractors are out to nickel-and-dime you.

Detailed Copies of All Estimates

Once you schedule your free estimate, you’ll need to make sure the contractor gives it to you in writing.

The written estimate will ideally include an outline of the work that’s needed, the cost of labor and materials, and any additional service charges. You’ll want this in writing to compare their offer with other estimates.

If a contractor doesn’t give you the estimate in writing, you have no way to prove if you’re overcharged.

It’s also important to review the estimate and ask for clarification on any fees that seem out of the ordinary. Make note of any answers and don’t leave your questions on the back-burner.

If the contractor doesn’t have time to review the estimate with you or to prepare a detailed explanation of the costs, keep looking. Unscrupulous contractors often sneak hidden charges into the agreement.

A Dedicated Office/Headquarters

Every established business will have a physical location or headquarters. When hiring a contractor, make sure they list their location. If they’re a mobile business that operates out of their house, that’s fine.

Trustworthy HVAC specialists stand by their repairs. If you notice something wrong after they work on your system, you need to be able to schedule an appointment with your tech. A physical location makes it easy to track them down as needed.

Technicians without a physical location or ones that travel to pick up business should be used with extreme caution.

Traveling contractors may fix a small problem, but once they’re gone, you have no way to get a hold of them in the future. This means you could end up paying twice for the same repair at best. At worst, you could fall victim to an HVAC service scam.

Emergency Service Appointments

You never know when your HVAC system will break down. And for many homeowners, it happens in the middle of the night when it’s least convenient.

Look for contractors that offer emergency service. It may cost more to have the problem fixed in the middle of a cold winter night, but going without heat or air conditioning can be hazardous to your health.

Fast Response Times

Before hiring a contractor, you’ll want to get estimates from different providers. That means you’ve had to schedule multiple appointments. Use this as part of your screening routine.

Look at the companies you contacted. Which ones got back to you the fastest? Which ones didn’t return your calls?

And how soon were technicians able to work you in for an estimate?

The ideal repair specialist will have fast response times, returning calls promptly and scheduling appointments in a matter of days, not weeks.

On-Going Maintenance Plans

Most high-quality HVAC contractors know that HVAC service is an annual thing. They want to keep your system running for years to come.

The key to any great HVAC system is frequent maintenance. Look for a company that offers HVAC maintenance plans.

These plans offer service discounts and priority appointments to help you get your broken system back up and running quickly. Most maintenance plans are available for a low monthly fee. And if you’ve had multiple repairs in the past, they can take the stress out of worrying about your system’s next breakdown.

Find the Right HVAC Contractor

Finding the right HVAC contractor doesn’t have to be a challenge. Look for professional, friendly, and experienced service every time.

When you find the right contractor, you’ll never have to worry about your system breaking down when you least expect it. They’ll be able to fix the damage quickly so you can stay comfortable year-round.

It’s starting to get cold outside, so you turn on your heater only to be screamed back at by a torrent of angry furnace sounds. 

Is something wrong with your furnace? Should you turn it off? 

Well, it depends on the type of noise you’re hearing. Furnaces make a lot of different sounds, and while some are a sign of serious damage, others are harmless. 

Take a look at this guide to learn why your heater is making noises and what to do about them. 

Understanding the Different Types of Furious Furnace Sounds

Furnaces can make a variety of terrifying noises. Each one indicates a different type of problem. 

When you hear any of these sounds coming from your furnace, don’t ignore it. These sounds are telling you something isn’t quite right inside your furnace. Leaving them alone will cause the problem to get worse, which means you’ll have to spend more money on repairs in the long run. 

Some of these sounds are warnings. If you hear them, you need to turn your furnace off right away and call a professional furnace repair technician as soon as possible. 

Wondering how you’re supposed to recognize all these different noises? That’s where we come in. 

We’ve put together a quick list of common furnace sounds and what they mean. 

Rattling, Buzzing or Vibrating 

Rattling, buzzing or vibrating sounds are usually cause for concern. Most of the time, you can make a few quick fixes on your own and the noises will go away. 

These types of sounds mean a few ducts inside your furnace are coming loose. There are a couple of different ways you can take care of this problem. 

If you have the right size screws, use them to tighten the loose ducts back into place. If you don’t have screws, you can also secure the ducts with a few pieces of duct tape. 

In some cases, the furnace itself might be rattling against the floor. Use a prybar to lift the unit off the floor enough to slip a rubber pad underneath. This should make the noise stop. 

Whistling 

Whistling could mean there are tiny holes or gaps in your ductwork. If you aren’t sure where the gaps are, you can turn on your furnace and try to find them by listening. There’s a good chance they’ll be close to where the duct connects to the furnace. 

Whistling could also mean your filter is clogged. A clogged filter forces the fan to suck air from wherever it can. As air is sucked through small spaces, it makes a whistling noise. 

Pull out the filter and see if the furnace is still making the whistling sounds. If not, it’s definitely a filter problem. 

If your filter is so clogged it’s preventing any air from getting through, you should throw it away and buy a new one. 

Squealing

This type of noise is a sign there’s something wrong with the furnace’s motor, belt, or bearing. While annoying, malfunctions that cause squealing aren’t dangerous. 

But again, that doesn’t mean you should leave them alone. 

These problems will get worse over time. They can create other, bigger issues in your furnace if you don’t take care of them. Make sure you call a professional technician to repair them as soon as you can. 

Chirping

Most of the time, chirping happens when you haven’t used your furnace in a while. As the furnace gets warmed up, it will start chirping. But the chirping should stop after a few minutes. 

If the chirping doesn’t stop or gets worse over time, you may need to replace the belt. 

Humming 

Humming sounds are most often the result of a poorly lubricated blower motor. If your furnace starts making this noise, you should turn it off and check the blower motor yourself. 

Make sure you give the motor plenty of time to cool before touching it! 

If the blower motor doesn’t seem to be the issue, there could be something more serious happening inside your furnace. Give your repair technician a call before you use it again. 

Banging

Hearing bangs coming from your furnace could mean a couple of different things. It depends on where the sound is coming from. 

Here are the two most common banging sounds you should be aware of. 

1. Banging When You Turn on the Furnace 

Sometimes furnaces will start banging when you first turn them on. Take a listen and find out if the banging is coming from the ductwork. If it is, you’re dealing with an oil-canning ductwork problem. 

The noise comes from a weak spot in the ductwork. To give it more support, take a thicker piece of metal and screw it around the duct. 

2. Banging When You Walk on the Floor Above the Furnace 

If the furnace bangs when you walk on the floor above it, the ducts are probably too tight. You can either loosen or rehang the duct. Those adjustments should take care of the problem for you. 

Loud Booming

This is a dangerous sound. 

A loud boom means your furnace has a delayed gas ignition. When this happens, the gas in your furnace builds up instead of igniting right away. When the gas does ignite, it creates a small explosion. 

Delayed gas ignition can cause serious harm to your furnace. But, more importantly, this can also be dangerous for your home and your family. 

If you notice a delayed gas ignition in your furnace, turn it off right away. Then call a professional furnace repair technician. You should always leave any repairs relating to gas to the professionals.  

Understanding Different Types of Water Heater Sounds

Like a furnace, your water heater can make its own array of strange noises. While these may sound the same as your furnace sounds, they mean different things. 

Here’s a list of common sounds and what they mean for your water heater. 

Cracking or Popping

As you use your water heater, sediments from the water build up inside the tubes. When you turn the water heater off, some of the water gets trapped underneath this buildup. 

It will force it’s way back through the buildup when you turn the water heater back on. As it does this, it makes cracking or popping sounds. 

This is more common in older units because they’ve had more time for sediment to build up. 

Knocking 

Your water heater pipes can heat internally and this causes them to knock against the inside of your walls. This can happen when you turn on the shower, run the dishwasher, or even flush a toilet. 

It’s not something you have to worry about. 

However, if you don’t fix the problem, your walls could sustain some damage. To prevent this, you can install a water hammer arrestor between the water heater and the appliance that causes the pipes to knock on the walls. 

Humming 

Your water heater element is probably vertical to your water heater tank. As the water flows around the element, it can create vibrations. This will make it sound like the water heater is humming. 

All you have to do to fix this problem is tighten the element. 

Tapping 

Hearing tapping sounds coming from your water heating is normal. The heat traps or check valves (whichever one you have installed) are what cause the noise. 

A heat trap or check valve sits at the top of your water heater pipes. They prevent water from flowing down the pipes backward. They also happen to make small tapping sounds. 

Screeching

You’ll hear your water heater screech when water gets forced through a small opening. This is usually the result of a valve that isn’t opened all the way. 

If you hear this sound, check the valves on your water heater. Opening them all can make the sound go away. 

When to Buy a New Furnace

Hearing a lot of strange sounds coming from your furnace or water heater may be a sign it’s time to get a new unit. As your furnace gets older, it will start wearing out. This can cause it to malfunction or develop other problems. 

Most furnaces last between 15 to 20 years. If your furnace is older than this, it’s time to buy a new one. 

Water heaters have a similar lifespan. However, if you have a tankless water heater, it can last for more than 20 years. 

Know Why Your Heater Is Making Noises Then Take Action

If you’re furnace or water heater are making weird sounds, there’s probably something that’s gone wrong inside the unit. Understanding why your heater is making noises can help you find the problem and take care of it. 

Some of the problems are minor, and you can fix them on your own with the right tools. However, some of the problems should be left to the professionals. If you notice anything that concerns you, make sure you call a repair technician right away.
