Replace Your Car's AC Thermal Expansion Valve or Orifice Tube

Biltmore Body & Paint

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 Biltmore Body & Paint, 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.

What Our Customers Are Saying

I was blown away with the service I got here. I have never reviewed a company before but I had to get on here and rave about Biltmore Body & Paint Shop. They bent over backwards to help me out. I was in a really bad situation with my car and they could have easily charged me way more then what they did. They helped me out big time and I will forever be grateful.

Got the run around from 2 different body shops in Asheville. Called Biltmore body and explained what was going on. They told me they could get it in the following day so I dropped off my wife's car the day before Christmas Eve and picked it up on New Year's Day. Fitment looks top notch, no trash in the paint, no cracks or swirls, and no orange peel. Will definitely be visiting them again if there's another accident.

Cannot say enough good things about my experience. Our 2004 Volvo was t-boned in a parking deck and 2 other body shops quoted the repairs over the threshold for totaling it. The car is in pristine, excellent condition and I told everyone we wanted to keep it. Biltmore P&B understood and did more than just shoot out a quick, over-inflated estimate. They actually called regional junkyards, found a replacement door, and made only the changes necessary?the others estimated costly new (factory!) bumpers and side lights that weren't absolutely necessary. Biltmore is a small, friendly business?not a "franchised estimate factory" like other body shops in town. I recommend them highly!
