Essentially, the air conditioner works on the successive heating and cooling of a super-volatile fluid called Freon. The latter first goes into the compressor and is compressed into gas form, therefore giving off heat and cooling the fluid consequently. The dispelled heat is then fanned out with the help of a rotating fan. Next, the liquid gets into the condenser and soaks up the surrounding heat to transform into vapor once again. So evidently, the surroundings cool off. This whole process goes on in a cyclical pattern, therefore bringing down the temperature in the room.
Apart from the 3 above major parts of an ac unit, the device also has a hot coil, a cool coil, one outside fan, one interior fan, and a control circuit in it Air Conditioning Repair Phoenix . The hot coil is put outside to dispel the heat out, and the cool coil is put inside to absorb heat. The control circuit modifies the temperature by regulating the rotation speed of the fans with the help of a potentiometer.
Of all its parts, the compressor remains the most valuable and expensive part of an ac unit. So, the air conditioner manufacturers always provide a warranty on the compressor. A compressor of exceptional make and quality has a long life and functions fine over years. And, if the original compressor gives you trouble, it can be replaced with a brand-new one. Its easy to buy a new compressor and fit in your old air conditioner. However, here it is always advisable to opt for the compressor of the same brand as that of the rest of the machine. However, the issue is that only a handful of companies make their own compressors. All the others simply buy them and install it in their air conditioning units.
The evaporator and condenser in an ac unit can be replaced too. So can the coils, in case they wear out. Any problematic coil can result in defective heat-dissipation, and lead to a major malfunctioning after that. The two fans are the most basic of air conditioner parts that can be easily replaced, precisely because they are fixed with screws on the outside, and with wires inside the air conditioner circuit board.
