What does the acronym "HVAC" stand for?

The acronym "HVAC" stands for Heating, Ventilation, and Air Conditioning. This term encapsulates the three critical components of climate control systems commonly found in residential and commercial buildings. Heating refers to the system used to warm indoor spaces to a comfortable temperature during cold weather. Ventilation involves the process of exchanging or replacing air in a space to improve air quality by reducing moisture, odors, and contaminants. Air conditioning is the process of cooling indoor air, removing heat and humidity, and maintaining comfort levels during warmer months.

Understanding this acronym is crucial for those working in the heating and air conditioning field since it encompasses the primary functions necessary for creating and maintaining a comfortable indoor environment. This knowledge is fundamental for technicians who must install, maintain, and repair HVAC systems efficiently.
