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 Discount Auto Clinic, 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.

Testimonials

    Discount Auto Clinic was recommended by a friend and their reviews were solid so I took a chance. Mike is the owner and he's genuine, straight up and explained the entire process...Car runs great and it was money well spent. Got an excellent warranty as well which is unusual for a transmission rebuild. Ask for Mike or Shelby!

    Excellent service. My daughter was next door in line to take her driving test. They told her the brake light was out, so she could not take the test unless I had the light repaired and she returned to the line by 3:20 pm. It was 2:55 pm. We drove to this place and explained what happened. There were several cars in the bay, but the mechanic stopped, ordered the part, and had us up and running by 3:06 pm.

    The service and staff, especially Mike, Shelby and Travis were friendly, helpful, proficient and genuine. Mike even helped by suggesting several ways for me to save money on my car! I really believe they had my best interest at heart and were not just out to make a buck... Fast service at a fair price is hard to find. This is definitely my go to place from now on!
