Is HVAC just cooling?

No, HVAC is not just cooling. HVAC stands for Heating, Ventilation, and Air Conditioning, and it is a system that is used to control the temperature, humidity, and air quality of a space. HVAC systems provide heating, cooling, ventilation, and air filtration to maintain a comfortable environment. Heating is used to warm a space during cold weather, while cooling is used to reduce the temperature during hot weather. Ventilation is used to bring in fresh air and remove stale air, while air filtration is used to remove pollutants and allergens from the air. HVAC systems are essential for providing a comfortable and healthy environment.
