HVAC stands for Heating, Ventilation, and Air Conditioning. This term is widely used in facilities management to describe the comprehensive system that manages indoor environmental conditions. It encompasses the processes involved in heating spaces to maintain comfort during cold weather, ensuring proper ventilation for air quality by circulating air, and conditioning the air to control humidity and temperature levels. Understanding HVAC is essential because it plays a crucial role in energy efficiency, occupant comfort, and air quality in buildings. Proper management of HVAC systems is vital for maintaining a safe and healthy indoor environment.
