Air Conditioning Service

Arizona is perhaps the harshest state on automotive air conditioning systems. With extreme heats and freezing temperatures components are pushed to their limits daily. Let our team of ASE certified expert technicians inspect your AC system. As summer approaches, Interstate Auto Repair will be offering  special deals on AC services to inspect and service your system and make any necessary repairs it may need. Stay ahead of the heat and stay tuned to schedule your appointment with us and make sure your summer is a cool one!



  • The compressor is a belt-driven device that derives its name from compressing refrigerant gas and transferring it into the condenser. While basically acting as a simple pump, the compressor is the core of your vehicle's air conditioning system.
  • The condenser's primary function is to cool the refrigerant. It is a heat dissipating apparatus that radiates heat released by compressed gases and condenses them into high pressure liquids. The location of your condenser depends on how new your car is, but typically it's found at the front of the vehicle, directly in front of the engine cooling radiator.
Receiver (drier):
  • The receiver is a metal container that serves as a storage receptacle for the refrigerant. It's also referred to as a drier because it absorbs moisture from the refrigerant and filters out particles of debris and harmful acids that would otherwise harm your AC system. Commonly located on the liquid line of the AC system, you should change your drier every 3-4 years to insure quality filtration and prevent any damage caused by these detrimental chemicals.
Orifice tube/expansion valve:
  • The orifice tube or expansion valve are  mechanisms that regulate the flow of refrigerant throughout the system. In addition to this, it also converts high pressure liquid refrigerant (from the condenser) into a low pressure liquid, so that it can enter the evaporator. Generally located at the evaporator inlet, the orifice tube or expansion valve could also be found between the condenser and the evaporator, or in the outlet of the condenser.
  • The evaporator is designed to remove heat from the inside of your vehicle; therefore it's a heat exchanger that's vital to your vehicle's AC system (not to mention your comfort). The evaporator allows the refrigerant to absorb heat, causing it to boil and change into a vapor. When this occurs, the vapor is removed from the evaporator by the compressor, cooling your car and reducing humidity.
