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 Good Neighbor 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.

    I cannot thank them enough. We were in town for an event when the alternator went out. It was by pure chance that we found Good Neighbor Automotive. Even though they had a full day of appointments, without even skipping a beat Jared said he would take care of us! They fixed the car faster than we could have imagined and we were able to hit the road for our 7 hr trip home! Thank you so much!!

    I've always been afraid to bring my car to a garage for repairs, because I've had tons of experiences where I felt I was severely overcharged. A few years ago I found a mechanic that I really liked. Unfortunately they ended up selling the business, and I was heartbroken. However! I recently needed a car repair, and I brought my car here. They took great care of me. They fixed my car, and they did not overcharge me! I could not be happier. I would highly recommend this place if you're looking for a decent repair shop.
