Replace Your Car's AC Thermal Expansion Valve or Orifice Tube
Craig's Service Center
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 Craig's Service Center, 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 had such a good experience - this was my 'test' for future work since I'm determined to avoid the dealership (New West Valley Location) at all costs. I'm at the front of the pack for Fiat - bought mine first, so now that it is getting older it is going to start needing repairs. I am pleased to have found you and will spread the word within the Fiat community the best I can for all the owners who will be right behind me in needing repairs. SO HAPPY I FOUND YOU!! I will absolutely be back for future repairs, tires, anything else as needed. Thank you for being such a great little local shop!
