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.

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

    I was in town for the week moving my son into his condo for school. On the way down my car temp started to go up to 3/4! Pulled over and I had a leaky heater hose. I googled auto repair in my area and MVAC popped up at the top and I noticed they had great reviews and in business for a long time and they were only one mile away. I called and spoke to a young lady and told her my situation. I know most repair shops schedule you days or weeks out but I was leaving in 2 days. That's when she let me speak to Marvin (I think the owner) and he said bring it in and we'll take a look. Marvin was very accommodating and he called me back 30 min after dropping off the car. He was able to replace the parts the same within a few hours and I was back on the road by 5:pm, 3 hours later. He did what needed to be done and didn't charge me extra or try to upsell me a new engine...lol OMG that's what I call a lifesaver! I was able to stick to my schedule and get my son moved in! I HIGHLY recommend Marvin and his shop to anyone!!!
