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 Trans International Transmissions, 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.

    By far the most genuine and best in the business. Jorge is probably the best mechanic in the Houston area. I had him fix a timing chain gear for me about a year ago. First and foremost he's a trans specialist and was very happy to get my car running for me. I would recommend him HIGHLY over anyone else. He's a very caring and knowledgeable man, and I won't let anyone else touch my car. Thanks Jorge sincerely!

    I took my Lexus to George based on a recommendation from a friend. From the moment I met George, I could tell he is an honest person. He rebuilt my engine, gave me a fair price and always kept me informed of the status of my repair. I would highly recommend him.

    I took my car to Trans International Transmission for a transmission problem last December. I always call them if I have a problem in my car, and they always tell me what is the best to do and if they can do it. They repaired a transmission leak in 3 hours without an appointment!

    I send all my transmission work to Jorge. He's one of the few mechanics I trust and can rely on. Super knowledgeable and gives honest recommendations.

    Recently took my truck (2002 F150) to a dealer for a new transmission. Called Jorge at Trans International instead, and was able to have the work done for a fraction of the cost. I called a few transmission shops in the area and Jorge offered the best deal, not to mention was very helpful. They do a complete rebuild including the torque converter rather than replacing only what needs to be done. Jorge called me to let me know when their tow driver got the vehicle, when it was in the shop, and when it was going to be ready. Only took two days. Give them a call.
