What HVAC means?

HVAC stands for Heating, Ventilation, and Air Conditioning. It is a system of components that work together to provide a comfortable indoor environment. HVAC systems are used to regulate temperature, humidity, air quality, and air circulation in a space. They are typically composed of a furnace, air conditioner, air handler, and ductwork. The furnace is responsible for heating the air, while the air conditioner cools it. The air handler circulates the air throughout the space, and the ductwork distributes the air to the various rooms. HVAC systems are essential for providing a comfortable and healthy indoor environment.
