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

Leo's Auto 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 Leo's Auto 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.

Was on a trip from FL to OH and heard some very concerning noises coming from my car with no way to diagnose on my own. They inspected my vehicle and recommended that I get new brakes. I told them I have a local mechanic in OH that I prefer to work with. They assured me that I was more than safe to get home and have the repair made there. They gave me peace of mind when they could have taken advantage of me and said they needed to be replaced on the spot. They also helped tuck a few wires as a courtesy that were exposed and hanging from my car from a bad trailer hitch installation. All around great experience. Juan was very helpful and honest and I would highly recommend Leo's!
