What is the primary function of an HVAC system?

The primary function of an HVAC system is to maintain indoor comfort through the processes of heating, ventilation, and air conditioning. This system is designed to create a comfortable living or working environment by regulating temperature, air quality, and humidity levels.

Heating is essential for keeping spaces warm during colder months, while air conditioning provides cooling during hot weather, ensuring that indoor temperatures remain comfortable year-round. Ventilation plays a crucial role in improving indoor air quality by allowing fresh outside air to circulate and helping to remove stale air or pollutants.

Each component—heating, ventilation, and air conditioning—works together to achieve this overall goal of comfort. While other options mention aspects relevant to HVAC systems, they do not encompass the full range of functions provided by HVAC systems, which collectively contribute to indoor climate control.
