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

Pro Tire & Automotive Services, Inc

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 Pro Tire & Automotive Services, Inc, 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 have always been impressed with their customer service, honesty, and loyalty. They have never steered me wrong and they always stand behind their work.

Wouldn't go anywhere else! Family owned, not corporate! Fair priced, friendly, excellent customer service! They take the time to explain what needs done! Not like other shops that use the "scare tactics" they will only sell you what absolutely needs done!

Steve at Pro Tire gives great customer satisfaction! He has always given me an honest opinion of what needs to be done to my vehicle, and has never recommended work I don't immediately need. When Pro Tire does a job, they do it right, but if there is a problem they will correct it. Routine maintenance rates are very reasonable.

They are not going to try to take advantage of you! I have been going here for over 2 years and they rock!
