Replace Your Car's AC Thermal Expansion Valve or Orifice Tube

McClure's Garage & Towing


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 McClure's Garage & Towing, 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.

Tires, near Gurnee, IL

The nicest guys! I've took my car due to a flat tire and was very pleased with promptness and very reasonable with pricing. Recently I took it in due to low pressure in one of my tires and they checked all of my tires and filled them up with air. Great customer service! I always refer people to McClures now! Thanks guys!

These guys are fabulous! Had a battery we purchased from them go bad within the warranty time and we walked in, they tested it and came right out with a new replacement. All this with smiles on their faces!

Haven't ever purchased tires before and really dreaded doing so. Told Matt, at McClure's, I needed help. He gave me 2 quotes, high and low end. I, then, did a lot of research locally, shopped Costco, also tried purchasing thru Amazon, and having someplace local install tires. McClure's was the best quote. I called Matt back on Friday, set appointment for 9am Monday. My son met me at McClure's at 9am. Matt said about an hour, son & I went out for breakfast, Matt called at 10:07, car was ready for pick up. Cost was below what was quoted. McClure's made what I expected to be a nightmare experience a very comfortable experience. They will be my go to garage for all car needs. Nice feeling to know I've found trustworthy people.
