Product Pick of the Week: Air Conditioner Compressors


Summer is in full swing, which means that you’ve probably been using your air conditioner for the past few weeks.  But have you ever wondered how your air conditioner works?  Well, you’re in luck because in this week’s Product Pick we’re going to talk about just that.  Our pick this week goes to Air Conditioner Compressors, the in-between step in the cooling process.

How it works

23869261 - air conditioning in the house, the design of business

Your air conditioner works a lot like your refrigerator does, but instead of a compartment and door keeping the cold air in and the hot air out, the walls of your home do.  Essentially, an air conditioner removes the heat from the air inside and transfers it outside using the cooling agent refrigerant.

There are 3 main components involved in the air cooling process and it’s a bit hard to talk about one without the other: the Condenser, the Compressor, and the Evaporator.

Your air conditioner uses a fan to draw hot air from your home into the unit.  The refrigerant begins as a liquid and as it reaches the evaporator, the refrigerant extracts the heat from the air in your home.  Because refrigerant has a very low boiling point, it quickly becomes a gas.

The Compressor is the step between the inside of your home and the outside.  When the refrigerant reaches the compressor it’s a low pressure gas.  Like its name suggests, the Compressor compresses the gas with a motor and/or pump.  This pressure packs the molecules in the refrigerant together to concentrate the heat present and increase the temperature.

The now hot and high pressure gas is hotter than the air outside as it flows to the condenser. Because heat travels from warmer to cooler areas, the heat from the home present in the refrigerant transfers outside over the condenser coils while the cooled air is blown back into your home.

As you can see, the Compressor plays a very important role in the cooling process. There’s a bit more that goes on when it comes to cooling your home, but we hope this gave you a better idea of how your air conditioner works.

Need a replacement for part of your air conditioner?  You can find the OEM parts you need for your Air Conditioner or Room Air Conditioner model on our website at  Many Air Conditioner repairs should not be completed without technical training, so don’t hesitate to contact a service technician if you’re ever unsure.
