The air conditioning condensing unit is an essential component of any air conditioning system. It is responsible for the cooling of the air that is circulated throughout the home or building. The condensing unit is typically located outside the home or building and is connected to the air handler or furnace inside. The condensing unit works by taking the hot air from the inside of the home or building and passing it through a coil. The coil is filled with a refrigerant, such as Freon, which absorbs the heat from the air. The refrigerant then passes through a compressor, which increases the pressure and temperature of the refrigerant. The hot refrigerant then passes through a condenser coil, which releases the heat into the outside air. The cooled refrigerant is then returned to the air handler or furnace, where it is used to cool the air inside the home or building. The air conditioning condensing unit is an important part of any air conditioning system, as it is responsible for cooling the air that is circulated throughout the home or building.
