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 Everything Automotive of Jacksonville, Inc., 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.

I cannot recommend this shop enough! I took my mom's car in yesterday and had the best experience. The owner, Tony, is a truly wonderful man. He is incredibly kind and you can tell immediately that he actually cares about his customers and their safety, not just the bottom line. It is rare to find a shop that is this honest, Tony charges a very fair price and doesn't try to upsell you on things you don't need. His employees clearly take pride in their work and treat customers with the same respect Tony does. If you are in Jacksonville, or even just passing through and find yourself in need of a mechanic, go see Tony. It's hard to find a business with this much integrity these days!

I took my son's car to the Honda dealership and was quoted a long list of repairs, so I called Everything Automotive for a second opinion. Chris answered the phone and was incredibly helpful; he took the time to go over pricing with me before I even brought the car in. Once at the shop, communication was great and everything was very transparent. I also met the owner, Tony, who was very kind and easy to talk to. This is a family-owned business, and it shows. There was no upselling, and as a woman, I felt completely comfortable and trusted them. Highly recommend!
