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 Maxi Auto Service, 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.

    I've used Maxi for quite a long time and have always been happy with their service and prices. Allen runs an efficient operation, and usually gets you in and out quicker than expected, with the problem fully resolved. I've recommended this shop to friends and will do so in the future.

    After a sudden incident with my sons tire. He needed air. This place was open and let him have air. Very nice and friendly people. Helped my son get his tire off so he could go get it fixed. Then helped him put it back on and charged him nothing.

    Excellent mechanics and a no BS attitude. If I need brakes or just about any other Auto service this is my first choice. Also they are an ASE Blue Seal certified shop.

    When my car broke down, my roadside assistance insurance paid for a tow, and I had my car taken to Maxi. I didn't have the money to pay for the repairs, and Maxi kept my parked there at no charge for several weeks until I was able to afford having it towed to my home. They are super nice and very professional. It's where I will always go in the future for car repairs and maintenance.
