Auto A/C Components explained
As confusing as auto A/C systems may be to some, it's nice to know that every A/C system uses pretty much the same components. That's true no matter if the A/C system is on a Jaguar, Mercedes Benz, GM, Ford, Toyota, Mazda or any other type of vehicle. Every system starts with a compressor and clutch assembly. That's used to pump the refrigerant. Of course there are always two heat exchangers; the A/C condenser and the evaporator. The evaporator absorbs heat from the air entering the vehicle while the A/C condenser gets rid of that heat. Expansion valves (TXV's) or orifice tubes are used to regulate or control the flow or refrigerant through the system. Then of course, all the components are connected with hose or line assemblies. Review the informative articles below for more details on the different components of the A/C system.

Auto A/C Service? Need help understanding what should be done?
Shopping for the right auto A/C service can be frustrating. One shop wants to charge what seems like and 'arm and a leg' while the other shop says it just needs some refrigerant or freon. Who do you believe? Maybe you've just been told that your A/C compressor is seized? What's next? What's the proper A/C service procedures you should be getting when your auto A/C system quits blowing cold air? These articles will help you better understand the proper A/C service that should be performed.
