The HVAC exterior unit is an important component of any home or commercial building’s heating, ventilation, and air conditioning (HVAC) system. It is the part of the system that is located outside the building and is responsible for the transfer of heat and air between the inside and outside of the building. The exterior unit typically consists of a compressor, condenser, and fan, which are all necessary for the system to work properly. The compressor is responsible for compressing the refrigerant, which is then passed through the condenser to release the heat and cool the air. The fan then pushes the cooled air into the building. The exterior unit is important because it helps regulate the temperature inside the building, ensuring that it is comfortable and energy efficient. Additionally, it helps reduce noise levels and can help improve air quality by removing pollutants from the air.
