What is the main function of the heating, ventilation, and air conditioning (HVAC) system?

The main function of a heating, ventilation, and air conditioning (HVAC) system is to regulate indoor temperature and air quality. This includes heating or cooling the air to maintain a comfortable temperature, as well as managing the flow and quality of air within a building. By doing so, the HVAC system ensures that occupants experience a conducive environment that promotes comfort and health.

In addition to temperature control, an effective HVAC system also plays a significant role in providing adequate ventilation, which removes stale air and introduces fresh air. This process helps to mitigate the buildup of indoor pollutants, allergens, and moisture, thus improving the overall air quality. Therefore, the primary purpose of an HVAC system encompasses both temperature regulation and air quality management, making it essential for creating a comfortable living or working environment.
