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

AutoChoice Service Center


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 AutoChoice Service Center, 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.

I am new to the area and got an oil change at the local dealership. I picked my car up from the dealership and was told it needed a brand new steering gear and much more that would cost me over $1800. I called my tech from back home since my car is only 2 years old and he told me to get a second opinion because it did not sound right. I called AutoChoice and explained my situation to Lloyd Nichols. He was very honest and upfront with me. They got my car in just two days later to just look it over for me to make sure it was safe. There was nothing wrong with my car that the dealership claimed. Lloyd was very honest, professional, and in the business to do good. I will be making this my Service Center for the rest of my time living in Bloomington. They looked at my car free of charge and then gave me a quote of about $1200 less than the dealership if I actually did need that work. I would trust them with my every car need. Great People!

I'm a repeat customer and don't plan on going to any other auto service center. I came in with a car that couldn't get started on its own and they assessed the problem and fixed it quickly and accurately. Adam, Lloyd & team are always on top of things and get it done right the first time. Each time I've been to the shop I've received nothing short of excellent service. Can't recommend enough!
