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

Beach 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 Beach 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.

The service was awesome. Dealing with the service manager and office folks was a real pleasure. They gave me a perfect diagnosis, and repaired my truck at a reasonable price. I've used them several times and have nothing but good things to say.

I recently got married and we went to PCB for our honeymoon. We were getting ready to leave when our gas petal went to the floor and would not accelerate. We were towed here where we had the best experience! We explained our situation and had to get back home in Georgia to make it to work the next day. The part we needed was not available until the next day or longer so they rigged it up for us good enough to get us home free of charge because he didn't want to make us pay for a job that "wasn't pretty" I'm glad we went there and I would highly recommend going there!
