Central air equipment is a type of HVAC (heating, ventilation, and air conditioning) system that is designed to provide a comfortable indoor environment in both residential and commercial buildings. It consists of two main components: an outdoor unit, which houses the compressor, condenser, and other components; and an indoor unit, which houses the evaporator and other components. The outdoor unit is responsible for transferring heat from the outside air to the indoor air, while the indoor unit is responsible for cooling the air and distributing it throughout the building. Central air equipment is typically more efficient than window units and is often used in larger buildings where multiple rooms need to be cooled. It is also more cost-effective than individual window units, as it can be installed in one central location and used to cool multiple rooms. Central air equipment is an important part of any HVAC system and is essential for providing a comfortable and healthy indoor environment.
