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 AGT Imports D/B/A J&M Auto Doctors, 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.

Testimonials

    I brought my 2003 BMW 530i into AGT because I was deciding whether or not to sell it. It had some problems that I thought would cost thousands to fix even though it has low miles and is very clean. Gus and his team fixed all outstanding issues for far less than I expected to pay, and when I (dumbly) rode into curb the next day and half pulled the bumper off, they fixed that free of charge. My friend had a similar experience with her Mercedes. Clean shop, efficient service and great people. A strong recommend.

    I had four tires put on. The mechanic performed the service quickly but accurately. The owner came over to introduce himself and to make sure everything was fine. I would recommend this place of business. They are very professional and friendly.

    This is the only place that I'll bring my wife's Mercedes. The owners are kind and mindful of other people, they do not overcharge and will keep your Benz in tip top shape.
