What does the acronym "HVAC" stand for?

The acronym "HVAC" stands for Heating, Ventilation, and Air Conditioning. This terminology is widely used in the building and construction industry to describe the systems, technology, and processes that regulate indoor environmental comfort.

Heating refers to the systems and methods that provide warmth during colder months, ensuring that spaces remain comfortable and livable. Ventilation is the process of exchanging or replacing air in a space to improve indoor air quality by removing excess moisture, odors, smoke, heat, dust, and airborne bacteria, thereby enhancing comfort and health. Air Conditioning pertains to the systems designed to cool and dehumidify indoor air, maintaining a comfortable temperature.

Understanding the components of HVAC is essential for anyone involved in building management, engineering, or environmental control, as these systems play a critical role in energy efficiency, air quality, and overall occupant comfort.
