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 Andersen's Foreign Car Service, LTD, 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.

The team at Andersen's has been terrific with my complex Volvo V60 issues. I had been taking it to the dealership but never again. Andersen's was diligent, conscientious and kind. They even provided a loaner. Thanks So much!!

They replaced an engine in our 1995 850 Volvo. Finding the engine was a chore and installing it took a lot of effort. Their charge for this was very reasonable and the service is always great. They are our go to people after our mechanic of 30 years retired a number of years ago.

Very thorough with trying to find the issue on my Audi. Very nice when needing to speak to them as well.
