Air Conditioner Compressor – How Does It Work?

Your Central Air Conditioner is like a refrigerator in your home. It will take air from the inside of your home and release it outside. So the compressor is a very important part of this system. So, how does a central air conditioning compressor work, and how does it cool your home? No Problem can tell you!

What is an Air Conditioner Compressor?

So what makes your compressor the heart of your system? Your compressor works the same way your heart does. The central air conditioning compressor pumps refrigerant through your AC system. The refrigerant is a fluid that sucks heat from inside your home and carries it outside. Keeping your system in shape is going to help prevent any issues that you will have. Always remember your filter is going to be your first line of defense.

How Does Your Central Air Conditioner Work?

  • The compressor will pump refrigerant from your outside unit to the indoor unit. At this point, the refrigerant is will start collecting heat and as it gets hot it turns into a vapor. At some point, it will not be able to grab any more heat. It will not travel back toward your compressor. Remember it is pulling that heat back with it.
  • The refrigerant comes back to the outdoor unit. The Compressor brings in the refrigerant and heats it until its a superheated gas.
  • At this point, the refrigerant has lost most of its heat. So it goes right back outside to start this process over again until it reaches the temperature set on your Nest Thermostat.

The Air conditioner is made up of three important parts. Your evaporator, condenser, and compressor.

How To Keep Your Central Air Conditioning Compress In Good Shape.

Keeping your outdoor unit clean will be a big help. We see a lot of trees and shrubs that cover your unit can cause major problems with the system. Do not ever buy a decorative cover for your ac. The unit is designed in a certain way. Every piece of the system is an intricate part to run a certain way. If you do something that covers too much. It will suffocate your system. This will help you look for air conditioner compressor problems.

Watch for low refrigerant. If your system is low on refrigerant the compressor will work harder to push enough refrigerant through the system to cool down your house.

Can I replace the air conditioning compressor or do I need a new one?
