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.

Reviews

I have been using Andersen's for a very long time. They are the most honest, capable, knowledgeable, and friendly family of people that I have ever met in or out of the auto repair industry. I trust them implicitly. I know they will always tell me the truth and give me a reasonable estimate with no surprise charges. If you have a foreign car, I have a Volvo, I would recommend Andersen's over anyone else. I would give them more stars if I could. And Willow the dog will gladly greet you and let you pet her and scratch her ears!

I've used Andersen's for years on several makes of cars that they service. They are an honest family owned business that I highly recommend to my friends and family.

I?ve driven past this building for over 20 years and if I had started taking my Volvo here back then, I could probably buy a new car with the money I would have saved. Not sure I?ve ever had a repair cost me less than $500.
