61. The Anatomy of the Central Home Air Conditioner
62. Central residence air conditioner support systems consist associated with two major pieces: a condenser of which sits outside the house along with the evaporator coil (often referred to as the A-coil) that sits inside the plenum regarding your furnace or perhaps air handler. The particular refrigerant within the A-coil picks up heat from your home and moves it to the backyard condensing unit. Typically the condensing unit supporter blows outside surroundings through the condensing coil to get rid of the heat. The particular condensing unit residences the three components replaceable by some sort of DIYer: the AIR CONDITIONING contactor, the start/run capacitor(s) and the condenser fan motor. Typically the condensing unit likewise houses the air compressor, but merely an expert can replace that will. The A-coil has got no parts that could be serviced by a DIYer.
