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

Ryan's Auto Care


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 Ryan's Auto Care, 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.

Exceptional! My son was in Lansing, MI on June 22, 2015 for a concert at the Loft with friends. Having auto issues so far away from home, Traverse City, MI. I was very concerned and lost trying to help my son get his car cared for and running again. I had hopped onto the maps of Lansing, MI and verified where my son was with his broken down car, and noticed Ryan's Car and Auto Care on the map close to my son's location. So I called Ryan's Auto service station and explained the situation, Ryan was very helpful referring me to 2 other service stations who may be able to help me in this situation. This first place I called was able to refer me to their towing service and get my son's car in, and serviced within the day,and the charges $$$ were very acceptable, considering the distance from Traverse City, MI and Lansing, Michigan. THANK YOU SO MUCH Ryan for your awesome help with this issue.

Ryans took care of my 2004 dodge stratus SXT coupe named Emma Frost at a very reasonable price and I always got her back quickly. I just had my newer (2000 jeep grand Cherokee named Crimson Dynamo) checked out there too and again, quick and reasonably priced. These dudes do some good work and deserved the praise they receive.

I've been blown away by how great the service is at Ryan's. Everyone has always been super accommodating to how car-illiterate I am, and unlike so many other shops, never take advantage of this. The online car evaluation that they provide you is a huge perk as well
