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

Rick's Auto Care & Tire 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 Rick's Auto Care & Tire 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.

What Our Customers Are Saying

reviewiconFront Royal, VA

I stopped by Rick's during the snow last week because my oil pan shield was dragging on the ground. Even though the sign said they were closed, they helped me. I went back yesterday to have a new shield installed. I think I've found my new home to work on my car. The customer service and the work are the best! They are definitely a great example of people helping each other, especially this time of year. Thanks Rick Jasper, and all the other employees.

Just moved in the area. Called Rick's Auto for Safety Inspection. Spoke to Jasper and he advised me to be there at 7:50am to fill out the paperwork and he could do the inspection at 8am, when they opened. Outstanding service, they did the Safety Inspection and I was out of there at 8:30. Very friendly and knowledgeable staff, specially Jasper. Will take all my autos there for maintenance and service.

Rick, Jasper, Mark, & staff, Just wanted to let you all know about the fantastic job you all did on my '92 Ford E-150 Mark III van. It literally runs and sounds brand new. The engine is so quiet I can barely hear it. The hesitation when you give it throttle is gone and everything is performing as it should now. Thanks again for keeping all my vehicles running great. Take care and we'll see you all down the road when I need service again.

My family just purchased our 2nd vehicle from Rick's. The 1st one is still running strong . We noticed a Explorer on the lot that was clean and runs smooth. And the price was more than reasonable we could not pass it up. Perfect vehicle for our daughter who will be commuting to school.
