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 Evans Automotive & 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.

    I was given a wait time of 2 hours and they had my window motor replaced in about 45 minutes! The gentleman I spoke with was very respectful. The price is better than any other shop around me. I Would not hesitate to go back to Evan's for any of my vehicle service needs.

    Best car repair experience! We had car trouble on I95 heading home from vacation. Being out of town, I called the first auto repair place that came up in the area. They recommended a towing service and rental car place. It was close to closing time but they went above and beyond to diagnose, repair and get us back on the road home. The entire shop went above and beyond to help us. Would highly recommend this company.

    My mother-in-law's Camry starting running rough while on vacation. We looked up AAA mechanics and found Evan's Automotive. Even though they were very busy they worked the Camry in and managed to fix it by the end of the day so that my MIL could have a safe drive home. Excellent service, and very accommodating!
