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 SOUTHWEST AUTOMOTIVE, 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.

    Wow, what a great place. Super nice and helpful guys. They're funny and easy to talk to, and explain things to you really well without talking down to you AT ALL. The shop is tidy and clean. I came in with what I thought was a simple fix, but it turned out to be catastrophic engine failure. :( SW Automotive could have made up anything in an attempt to get more work out of me, but instead, they gave me a bunch of tips about car shopping and how to get into a more reliable car. They even took a quick look at a used car I was test-driving and offered advice on that. Many thumbs up for this place.

    The owner, Rick and his staff are men of integrity, ethics, honest and solid value standards. You will not go wrong with them. I most definitely recommend this automotive repair business! It is top-of-the-mark! I find it outstanding these men actually listen to a woman talk of what seems to be wrong and they take the time to check out every detail.

    Have a 2009 Hyundai and engine light came on. Ran my own test and 5 different codes came up, all of which I did not have the ability to repair. Took it to SW Automotive and was prepared for the worst but also heard great things about SWA so prayed for the best. Turns out carbon build up in the fuel lines caused the error codes, $89 and I was out of there!! I am always pessimistic about repair shops as they think they can easily trick me into thinking repairs are needed when they are not. Well SW Automotive now allows me to be optimistic about my future auto repairs.
