Replace Your Car's AC Thermal Expansion Valve or Orifice Tube

Your car or truck's AC system is under extreme pressure and the thermal expansion valve or orifice tube monitors the amount of pressure and the temperature of your A/C system. It calculates the precise amount of refrigerant that can safely go into the evaporator. A failing expansion valve or orifice tube often causes a vehicle's air conditioner to blow hot air.

Replace or Repair

  • Expansion Valves: Too much refrigerant causes your evaporator to get too cold whereas too little refrigerant would result in inadequate cooling. The expansion valve is a complex valve that regulates refrigerant flow. This process of metering the refrigerant adjusts the flow according to the temperature of the refrigerant in the evaporator coil. Talk to one of the pro mechanics at Mickey's Car E.R., as this part can be replaced on its own and does not require the entire replacement of the AC assembly.
  • Orifice Tubes: Unlike the expansion valve, the orifice tube is a simple fixed device with no moving parts. It therefore cannot vary the flow of refrigerant into the evaporator, but rather causes a permanent restriction in the system. However, like the expansion valve the orifice tube regulates refrigerant flow through the system and filters debris which may come through in its screen. Often fixing a "bad orifice tube" requires replacing the entire evaporator assembly.

    What a great experience! Knowledgeable and professional! The turbo went up on my Acura RDX. The dealer pronounced my car DOA. They gave me an inflated estimate and insisted I was better off getting a new car. A close friend of mine recommended that I take my car to Mickey. I did just that and Mickey and his top notch team of Car Docs went to work on the patient. They were able to resuscitate her and save her life for a fraction of what the dealer wanted. Mickey kept me informed throughout the process. Even sending me video of the surgery! The turnaround was quick and I was back on the road in no time. Seriously, whether it's an oil change, or a major repair, Mickey and his team are equipped to do the job. You can expect an honest diagnosis, fair price, and outstanding workmanship. Mickey stands behind his work. I highly recommend Mickey's Car E.R. I was completely satisfied with my experience.

    Great job all around, was a pleasure to do business with James and Mickey. Very professional and a clean waiting room. We felt very comfortable with our young 1 1/2 year old there inside waiting on an inspection. Thanks Mickeys!

    It is so hard to find a mechanic you can trust these days! I highly recommend Mickeys Car repair shop. I was treated with respect, quoted a fair price on getting my tire repaired and it was fixed really fast. Mickey owns the place and you can tell he's a man of integrity who runs a business committed to providing excellent service.
