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 Circle Automotive, 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.

    Blessed to have come upon this shop. My family and I were on a road trip from New York and our car broke down near Clovis at 8pm on Friday. Our Honda Odyssey couldn't take the hilly up and downs of the Cali hills. AAA towed us to this shop but since it was late we would have to wait till the morning to talk to anyone about the work. The shop says it's only open weekdays and Saturday by appt. So we decided we would come in the morning and possibly someone would be there working. We came back the next morning and John was there. He is a very generous and caring man. He decided to look at our car to see what's wrong and ended up helping us out. The day before, we already were thinking the road trip is down and out, and the super old car is dead. Everything was amazing, from the service to the conversations. Huge thank you to John!!

    First time to use Circle Auto service, read reviews and chose to go there. I wasn't disappointed. Very good job, took care of my AC. Done in one day. Very happy. Will go there again if needed.

    Very trustworthy and dedicated owners and mechanics. They are very fair in their pricing. They are also thoughtful about diagnostics and figuring out exactly what your car needs. They never offer things that you don't need. In fact, many times I have had other dealers and mechanics recommend services and then bring it to Circle Automotive for a 2nd opinion and have them tell me that they didn't think it was necessary. They have definitely earned my trust.
