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 LTM Quick Lube, 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.

    Thank you for fixing my truck, everything turned out perfect (replacing the oil switch on my Duramax). Excellent communication from the mechanic also. This is just a great place of business , I highly recommend these people.

    Quick in and out oil change. I love the vacuum out service they do, especially in the winter when it's all salt. I've never gotten hassled/up-sold on products I don't need (air filter etc). They even sometimes send out emails with coupons! Both my wife and I go here.

    They do a through check of all the fluids and components on maintenance. Anytime they find something that needs replaced, they physically show you the issue so you know they are telling you the truth. They also show you the color of the oil before and after they change it so you know it was done correctly. Service at this location is worth every penny.

    Ah ha! First oil change in my new car - the technician knew each step (which buttons to push) to reset the vehicle oil life. I was impressed.
