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

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 X-Pert 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.

Shelley and Frankie are outstanding employees, friendly and efficient. All service is very thorough, but pricing is highly reasonable. Cannot say enough good things about their service and expertise. First time I have ever completely trusted this type of service.

    Had to drop off my car before they opened...that was easy, as they have the lock box, envelopes, pen, all ready in place. Felt very comfortable leaving the car in their lot that morning. Contacted by the shop to let me know the status of the repair, and estimated time to be completed. Quality of the work was exceptional. Test driven three times to make sure everything was completed...they noticed one sound that was not there before, and repaired it at no cost...tightening of something... but no charge to take care of that issue. Overall, I am very impressed and satisfied that I have found a mechanic so close to SaddleBrooke Ranch, that I can rely on for years to come. You won't be disappointed.
