Heating, Ventilation and Air Conditioning (HVAC)

Heating, Ventilation and Air Conditioning (HVAC) refers to the systems used to manage temperature, humidity and air quality inside buildings. Heating equipment provides warmth, ventilation introduces outdoor air and removes stale air, and air conditioning cools spaces and can remove excess moisture. HVAC systems may include boilers, heat pumps, chillers, fans, ducts, filters and controls. Their energy use and environmental impact depend on equipment efficiency, refrigerants, energy sources, building design, maintenance and operating practices. Efficient HVAC systems can help reduce energy consumption and operational greenhouse gas emissions while maintaining occupant comfort and indoor air quality.
