The HVAC (Heating, Ventilation, and Air Conditioning) system is a vital part of any home or business. It is responsible for providing the necessary heating, cooling, and ventilation to keep a space comfortable and safe. HVAC systems are designed to regulate the temperature, humidity, and air quality of a space, and they can be used to reduce energy costs. HVAC systems are composed of several components, including a furnace, air conditioner, air handler, evaporator coil, condenser coil, 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 evaporator and condenser coils regulate the temperature. The ductwork carries the air from the furnace and air conditioner to the various rooms in the space. HVAC systems are essential for providing a comfortable and safe environment in any home or business.
