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 Auto Surgeon, 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.

    Just a word of thanks for the top notch done to Wema's Carolla and for the thoughtful communication with our Tanzanian exchange student. Not only did you fix her car, but also handled arranging towing, all in a narrow window of time. Wema is delighted to have her car back, running better than ever. Couldn't be more happy with your service!

    My son limped his vehicle into Auto Surgeon's parking lot . The vehicle is on its last leg and we just needed to get it up and running for a few more weeks til my son graduates. The proper repairs were out of the budget so Bill came up with a solution that made sense for this vehicle, Bill didn't have to adapt for us but he did, and the price was more than fair. Don't hesitate to call Auto Surgeon for any repair.

  • I have passed this place on the bus every day for 6 years and have always gotten a smile out of their sign out front having such nice little positive messages. So when I finally got a car and needed my brakes done, they were my first choice. Not only were they incredibly friendly and professional, they identified what I thought was a minor inconvenience and explained how it could be a problem down the road (pun very much intended) while fixing it for me. I will absolutely be coming back for anything I need done in the future!

    My daughter brought her GMC in for a noise in the suspension and a air bag issue- Bill and his staff did a great job in diagnosing and repairing the vehicle with keeping us updated on the process. Thank You

    My husband has taken his car to Auto Surgeon for many years and has nothing but praise for their expertise and customer service. We both trust that whatever the problem, we're in good hands with Bill and his team. Today it was my car's turn to need repairs. Within 90 minutes of dropping it off, they contacted me with a diagnosis and an estimate. By early afternoon, my car was ready. First-rate experience, start to finish. No one wants car problems, but if you have them, this is the place to go.
