What is the HVAC system in a building?

The HVAC system in a building is a complex system that is responsible for providing heating, ventilation, and air conditioning. It is made up of several components, including an air handler, furnace, evaporator coil, condenser coil, and ductwork. The air handler is responsible for circulating air throughout the building, while the furnace heats the air. The evaporator coil cools the air, and the condenser coil removes the heat from the air. The ductwork is responsible for distributing the air throughout the building. The HVAC system is designed to provide a comfortable environment for occupants and to maintain the building’s temperature and humidity levels.
