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

Three Points Automotive


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 Three Points Automotive, 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.

Great service! Friendly staff! They came highly recommended by several of my family members and they gave me a fair quote that was far better than others around the area.

Best car service I ever had. They went out of their way to fix my mirror and get mt SUV ready to pass over to my son. If there's a problem with something, they will work to resolve it. Honest and reasonable prices.

A rare find - a shop I trust!. I would highly recommend Three Points Automotive. They have always gone out of their way to take care of my personal vehicles, as well as, the fleet at work. Their customer Service is impeccable and while I can't say they are infallible, I can say that when they've made a mistake, they have gone above and beyond to make it right. This is the best relationship I've ever had with an automotive shop! Love these guys!
