What does HVAC stand for?

HVAC stands for Heating, Ventilation, and Air Conditioning. This term encompasses the essential components of a climate control system used in residential, commercial, and industrial buildings. The "Heating" part pertains to the systems that provide warmth, typically through furnaces, boilers, or heat pumps. "Ventilation" refers to the process of exchanging or replacing air in a space to provide fresh air and remove indoor air pollutants, odors, and moisture. Finally, "Air Conditioning" involves cooling and dehumidifying the air for comfort in warmer conditions.

This terminology is critical in the field of engineering, especially in designing and maintaining comfortable and safe indoor environments. Understanding HVAC is fundamental for professionals involved in building design, construction, and operation, as it directly impacts energy efficiency, air quality, and overall occupant comfort.
