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

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 RG Motorworks, 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.

    This place is awesome!!! So glad I finally found a reputable, honest, and fair mechanic in Las Vegas!!! I highly recommend this place if you have any work needed on your car. After months of bringing my car back and forth from the dealership, because they "couldn't figure out" what the problem was, this guy figured out the problem within an hour...thanks RG Motorworks!!! Just went back for some more work on both our cars and again, very satisfied.

    Still drove out from the west side to come here for my maintenance needs. Honesty, efficiency and reasonable prices are what have kept me coming. Plus Tita's fresh gourmet coffee.

    I was referred here by Hector who now works here. My window regulator went out. Price of $443 including tax and labor was fair but you always pay more for Mercedes Benz. I dropped it off day before and they had it ready by noon. I'll be going back.

I can assure you that you will get great deal and an honest evaluation on your car. Give these guys a try. Thanks RG Motorworks.

    RG Motorworks is the only place I trust with my Beamer and SUV, never did I have to come back for a back job. Not like dealerships or other shops that will squeeze you for every penny that you've got. Friendly people and great mechanics. I will never go to another shop again. Keep up the great work and more power to the business. I highly recommend this place to all car owners out there!

    Feel very fortunate to have found RG Motorworks to do the regular annual required services to our 12 years old Mercedes Benz . Having moved from the east coast where there are plenty of authorized and reliable Benz service shops we were worried what to expect from our few choices in town. Everyone in RG MotorWorks was very professional and helpful, services on my car were performed as those I would expect from Benz dealership mechanics, and as someone else mentioned, without any surprises on your bill . That sweet lady in the office even arranged for our car service when she found out we would need a vehicle while they are working on our car. The best part was that she extended a special shop discount to us with the car rental place. Thank you RG Motorworks and we will definitely see you again on our next service !
