What is the primary purpose of an HVAC system?

The primary purpose of an HVAC system is to maintain indoor air quality and comfort. This encompasses a variety of functions, including heating, ventilation, and air conditioning, which together help create a stable and pleasant indoor environment. By regulating temperature and humidity levels, and ensuring proper ventilation, an HVAC system effectively contributes to occupants' comfort and health.

While regulating indoor pollution and maximizing energy efficiency are important considerations for HVAC systems, they are secondary to the overarching goal of providing a comfortable and safe indoor atmosphere. Additionally, focusing solely on heating does not encompass the full range of services that HVAC systems offer, as they also include cooling and air quality management. Thus, the emphasis on maintaining indoor air quality and comfort accurately captures the main objective of HVAC systems.
