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 Doucette Mobil Service Station, 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.

    Nothing beats the neighborhood gas station with mechanical repairs! Melvyn always provides me with excellent service! I can't believe how many nails I have had removed from my tires here. Louis, the head mechanic, is awesome too! They open at 8 am on Saturdays. They have the best prices for tires. Call around, you'll see. Ask for Melvyn, he'll help you out!

    It's really refreshing to have an honest auto mechanic in this area. Don't go to the dealerships, take your car here first. I had a rattle noise coming from the undercarriage and they fixed it while I waited and charged me very little. Another mechanic would have kept the car all day and probably charged much more. Highly recommend them!
