The answer to 'how does HVAC system work' is that an HVAC (Heating, Ventilation, and Air Conditioning) system is designed to regulate the temperature, humidity, and air quality in a home or building. The main components of an HVAC system include the furnace, air conditioner, and ductwork. The furnace generates heated air that is distributed through the ductwork, while the air conditioner removes heat and humidity from the air. These components work together to maintain a comfortable indoor environment year-round.
HVAC systems use a refrigerant, such as Freon, to absorb heat from the indoor air and transfer it outside. The compressor, condenser, and evaporator coil work together to facilitate this heat exchange process. The ductwork in the home or building then distributes the conditioned air throughout the space. HVAC systems also include thermostats, filters, and other controls to regulate the temperature, humidity, and airflow.
