HVAC stands for Heating, Ventilation, and Air Conditioning. It refers to the technology and systems used to control the indoor environment, providing comfortable living conditions by regulating temperature, humidity, and air quality in residential, commercial, and industrial spaces.

The concept of HVAC dates back to ancient civilizations. The ancient Romans used hypocaust systems to circulate hot air beneath floors, while the Greeks used intricate channels to supply cool air to buildings. However, modern HVAC systems as we know them today began to evolve during the Industrial Revolution when advancements in steam technology led to more efficient heating systems.

In the late 19th and early 20th centuries, the development of electricity and refrigeration revolutionized HVAC. The invention of air conditioning by Willis Haviland Carrier in 1902 marked a significant milestone, enabling not only temperature control but also humidity control. This innovation transformed industries like healthcare, manufacturing, and entertainment, making it possible to create controlled environments that were previously unattainable.

Today, HVAC systems encompass a wide range of technologies, from central heating and cooling systems to ductless mini-split units and smart thermostats. With a growing emphasis on energy efficiency and environmental impact, modern HVAC systems are designed to provide optimal comfort while minimizing energy consumption and carbon footprint.
