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

Tallahassee Car Care

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 Tallahassee Car Care, 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.

reviewiconBetter Than A Dealership

Great place to get your car serviced! I went in for an estimate and they were able to have it fixed the next day! They told me ahead of time that there could be more problems when they got it on the lift so that there were no unexpected expenses which is great! Bottom line- if you need your car repaired, come here.

reviewiconFast and Courteous

Went in knowing what I wanted done and let them know the issues I'm trying to fix. They respected it, suggested possible other fixes if the requested didn't fix it, but didn't get pushy. Got me in and out pretty fast despite being a walk in. My only regret is I hadn't gone to them years ago. Could've saved so much money and headaches if I went with them
