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.

    Fair and honest. Great service. I've been going here for years with several cars, Toyota, Ford, Acura, BMW they do it all. They recently took care of my son's brakes and with him being a new driver I feel so secure knowing they did the work. I highly recommend!

    Finding a mechanic is stressful. Visiting Mission Village Auto renewed my faith in the industry. They were compassionate and patient while going above and beyond to diagnosis the issue with my car. If you are looking for a reliable and respectful garage, look no further.

    Best shop in San Diego, fast and reliable service. They've completed a variety of large and small repairs on my vehicle, and I wouldn't trust anyone else. Really a fantastic place. Highly recommend.

    This place is hands down the best automotive care center in San Diego. I've had a couple vehicles in and out, for big jobs to simple repairs and I each time, was comfortable in the abilities of the techs they have on staff. I would 100% recommend this establishment to anyone needing their vehicle serviced. I will be using this place until the combustion engine is outlawed haha. Plus the muffler shop across the way is very good as well.

    They were so nice to work with and super friendly, they were able to identify the issue quickly whereas another shop was not, they fixed damage the other shop did, and they did it all quickly! I'll definitely be returning for my next auto repair needs.
