Why does my air conditioner keep freezing?

Why does my air conditioner keep freezing?

Cold air from the home is needed for the coil to stay cold and keep the temperature above freezing. A freeze up can also be caused by low refrigerant and improper fan operation. Faulty thermostats and drainage problems are often the causes of a freeze up. If you have a window AC unit, you can use a hairdryer to unfreeze the coil. It’s also a good idea to check the drainpipe for any blockages, such as debris and twigs.
