HVAC (pronounced as an acronym or as “aitch-vac,” depending on individual preference) stands for heating, ventilation, and air conditioning. HVAC systems are designed to regulate all of those functions within an indoor environment – whether residential or commerical. While technically many appliances have HVAC properties, the term usually refers to a large system of vents and ducts used to service a house or workplace.
