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 Affordable Kar Kare, 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.

    Russell is the man. I spent a lot of money. But he told me every problem, even describing the sound so I knew what was fixed and his only concern was my safety. Even when he knew I didn't get paid till Friday he fixed it and said pay it Friday. His concern was my safety. That's not just a good mechanic but an awesome human.

    I have seen the reviews but my experience with this shop was great , maybe they had different mechanics then but I brought my Trans Am to them for a problem that 2 other shops in mesquite could not diagnose or fix ! Friend referred me and we'll all I can say is this is the only shop who could diagnose and fix my car . They are very honest and up front on what your car needs and doesn't need and they checked everything even let me know that certain belts would need to be changed soon and showed me so I will never take my car anywhere else.
