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 Mission Village Auto Care, 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.

    Brought my car in for a standard service. Was able to get in very quickly and waited while they completed the oil change and related service. I was out of there in under an hour. Good coffee, too.

    I was referred to come here by discount tires to get my tire pressure monitor fixed as It broke. Unfortunately, I had a frozen lug nut. Discount tires was not able to fix it. So, they referred me to Mission Village. I ended up going there about two weeks later and they were able to fix my lug nut. Give my vehicle a check up for 100,000 miles and take my car to discount tire to get my tire pressure monitor replaced. they also took my car to discount tire to get the lug nut replaced so as a drop off and pick up that was made significantly easier. Great customer service would highly recommend them
