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 Gallagher's Auto Service, 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.

What People Say About Us

  • reviewicon

    Dropped off my car here today for a variety of stuff. Forgot my emissions inspection was coming up when I dropped off, called later and not only they were more than accommodating, but they rotated my tires as well without me asking because they caught that there would otherwise be an issue with the tires. Promptly completed, great quality, and most important of all--the price was EXTREMELY fair. Bill is also extremely professional and has great customer service. Definitely coming here again. Highly recommended.

    Quality work, honest, and a fair price. If you don't want to be concerned about being raked over the coals or having unnecessary work done, look no further than Gallagher's.

    I took my Mercury Mountaineer in for service. There had been a rumbling noise while accelerating. For all I knew it could have needed a new transmission but Bill Gallagher did not try and sell me a new tranny when in fact all it needed was in fact an additive added to the fluid to help with the overdrive (a known Ford/Merc. problem.) Thank you Bill for your honesty. I trust his shop implicitly. I highly recommend his shop to anyone.

    Our experience with Gallagher's service was outstanding! Bill was very professional and treated us with the utmost respect. We have found their prices to be reasonable and we are very satisfied with their work. We will be going back to Gallagher's from now on and we will recommend their services to others.

    Lucked out and found Bill's shop and now bring everything to him. Excellent mechanics, MB experts (as well as other German models and many other foreign and domestic vehicles). They now service everything from my '96 Jeep Cherokee to the MB. They actually repair things instead of rip and replace. They are always upfront about pricing and will give you an honest estimate before starting the repair.
