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 Foreign Affair Import Car Repair, 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.

Bob repaired my car when I could find no one else in the area who'd even touch it, did it with a smile, and did a great job. I would definitely recommend anyone, with any kind of car, to this honest, hard-working, uber-good place, but especially those of you who've been looking for a really good, honest mechanic for your Volvo!
None better. My vintage MG had a slight surge that I put up with for years, and several MG 'gurus' had been unable to fix. Mac fixed it by polishing an internal part to make it smooth - car hasn't run better in decades. And like others have said in their reviews, I was amazed when he called me on a Sunday night to tell me what he had found. I'm a fan!
Foreign affair is run by a wife and husband. I came across this place accidently when I was having problems with my Infiniti FX35 near RAFB. They are extremely honest, I check their prices on parts and they were not ripping me off. I was very impressed with the communication and the ease of the process.
Best Repair Shop I have ever been! I normally called them to repair my 2002 Volkswagen Passat. They always call me after they check out the car to let me know what issue (s) my car has and to let me know how much parts and labor would cost before they begin the repair. My wife and I are very satisfied with this shop and would not trust our cars to no one else in town.
