There are so many different parts that work together to make your air conditioner cool your home. Your air conditioners compressor is one of the most important parts of your cooling system. Without a working compressor you wont have cool air. Your compressor is located on the outside of your home. The compressors purpose is to circulate the refrigerant that is needed for heat removal. Electricity is sent to the compressor to make it and various other parts run to cool your home. The compressor is powered by a motor that consists of a piston and a cylinder. Refrigerant is in gas form when it enters the compressor. The compressor compresses that gas and raises its temperature to make it more high pressured. This high pressured gas is forced through lines that lead to the outdoor compressor where the refrigerant expels the heat and is turned back into liquid. The liquid goes back into the indoor unit where it evaporates and removes heat from your home and then starts the same cycle over again. This is the process that cools your home. The air conditioner removes heat from your home, not add cold air. The compressor needs to be cared for each year to make sure that your home will be cooled sufficiently. Any dirt and grime can get into the motor and damage it. This can cause leaks of refrigerant through various connections and a big enough loss of refrigerant can damage the compressor.
