So I’ve had some people ask how does the ac compressor system breaks down. Below are a couple of useful charts and diagrams that will probably explain it better than I can.

The air conditioning compressor turns liquid freon into gas freon. The condenser cools the gas down into a liquid, sending it to the evaporator. The evaporator turns cool liquid into cool air, removing the heat from the cabin. The warm liquid goes back to the compressor. Then it starts all over again

Some keys to the system are that the size of the fins on the ac condenser directly affect how well it performs. If those fins are not working very well then the gas will never get very cold and performance will suffer. We have done lots of articles about condensers, so feel free to do a search and find those.

Check out the diagrams for more info.
