Replace Your Car's AC Thermal Expansion Valve or Orifice Tube
Andersen's Foreign Car Service, LTD
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.

I was visiting family in Conifer and the antifreeze reservoir to my Volvo cracked and was leaking. There was no garage in Conifer that would service my C-70. After researching garages I came across Anderson's web page and saw that they service Volvo. When I called them they indicated to me that the first available appointment was over a week out. I initially spoke with Ryan and explained that I was visiting family and was to drive back to Chicago in a few days. He said he would talk to a manager and get back with me. When he called back he said that they would work on my car but it may take a couple of days. I said that would be fine as I just needed the car by Friday. I was impressed by the service because the car was done one day after it was towed to the shop. When I came in I talked to Kurt, like everything else this was also a pleasant experience. He said they they looked over the car and other then the repair everything else was fine. They also replaced the battery in the key fob which was also low. I want to say thank you to everyone at the shop. It’s a stressful experience then your car needs a repair after driving and you are a 1000 miles from home. I will definitely use them again if needed when in the Denver area. This is a shop I would recommend to anyone for their foreign car service. They were professional, courteous, skilled and trustworthy. I wish them continues success because they deserve it!
