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

AutoChoice Service Center


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 AutoChoice Service Center, 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 a custom built car that has mostly Subaru parts. Repair shops all over Bloomington IN refused to work on it because they lacked the interest in doing anything out of the ordinary repair. Even specialty foreign auto repair stores wouldn't even look at it. Someone told me about AutoChoice and the work they did on their custom built car. I called and they agreed to look at it right away. After having it for two days they had diagnosed the problem and repaired the simple thing that was keeping it from starting(faulty battery cable). Replaced the part and charged a very reasonable fee for repair. I can not say enough good things about Adam and his staff at AutoChoice. "Your car is really easy to work on" was the quote of the day. They have a new and loyal customer in me.

I got a pre-purchase inspection last minute from these guys. They answered every question I had, and we even cracked a few jokes while I was waiting. If I lived in this area I would definitely be a repeat customer.
