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

Mike's Motor Zone

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 Mike's Motor Zone, 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.

10 Stars!!! My radiator started leaking and smoke was coming out from under the hood right near Mike's place (which happens to be across from my daughter's preschool)! Mike and his wife took time out of their schedule to help me out, give me a quick diagnostic, give me a free loaner car, and get my kids home ASAP. They were such a blessing and we're so willing and humble!!! Amazing place, amazing service!!! Repairs to my radiator were done on time and on budget. Great experience!
