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

Classic Auto Service

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 Classic Auto Service, 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

Trustworthy, honest, reliable work! (YES, at a shop! lol) I've been bringing my car to Classic Auto for (about 10?) years now. The first time was after I received a quote from another shop, someone told me to "go see Pete", and I'm glad I did. My car was fixed for about 25% of the price I was quoted elsewhere (a lot of the stuff they told me I needed, I didn't). Over the years I've had a lot of work done on not only my car, but my kids and parents cars too. I'm planning on keeping my car that already has over 240k miles on the road for a long time, and I trust them to help me do that.

Great Mechanic!

Pete has taken care of my cars since he opened the shop. He and his staff always do excellent work for a good price - and I'm very satisfied with the quality of his service. I am struck that he delivers on his promises; he doesn't promise what he can't deliver. And I have received honest auto advice, even if Classic does not end up doing the work. I can't speak highly enough of Pete and his crew. If you're unhappy with your mechanic or national chain shop, give Classic Auto Services a try. I think you'll be glad.
