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 Packard's Shell, 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.

Bill and the Team were incredible!!! My family and I were heading he Florida on Spring Break and had car trouble at midnight on Thursday. I called Friday at 7:30am, explained my predicament, and Bill took me right in...our van was fixed and we were back on the road before noon. The entire experience exceeded any and all expectations!!! The Team's professionalism and concern for getting my vacation back on track was exemplary! It was the best experience I have ever had with any car trouble...I wish Packard's was in Michigan!!! Fair, honest, and dedicated to service....a great recipe!
Awesome service! These guys are honest, straight forward and very competitively priced. I have used them for many years and will continue doing so as maintenance and repairs are needed.
