Replace Your Car's AC Thermal Expansion Valve or Orifice Tube
Advantage Auto Service
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 Advantage Auto Service, 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 people are very nice they do good work and I would recommend them to anyone who needs work on their vehicles.

I was pleased that Scott was able to mount and balance tires he did not provide. Advantage auto should add their name to tire rack installers. I like to pick the tires that best fit the car I am driving. Scott's team mounted and balanced perfectly. Also as a full service shop pointed out that I urgently needed a new battery cell died the day before and that rear brakes need attention. The biggest surprise is their beautiful location, a great place to walk your dog while waiting for your car to be fixed. Dog friendly shop! Highly recommend!
