HVAC is an acronym that refers to the Heating, Ventilation, and Air Conditioning systems in a home or building. In common terms, HVAC refers to the home's furnace (or other heating system), air conditioning, or other mechanical ventilation systems (such as exhaust fans).

These systems are important components of the home and should be thoroughly considered when remodeling and when making energy efficient improvements.
