Replace Your Car's AC Thermal Expansion Valve or Orifice Tube
Quality Auto & Diesel Repair, Inc.
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 Quality Auto & Diesel Repair, Inc., 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.

These guys are awesome. Sent my 2013 pathfinder to them to replace the alternator( first time i have ever had someone else work on my vehicles) and they did it cheaper than anywhere around. They do high quality work and have high quality employees. They are very helpful and able to find parts quickly that are hard to get. This car rides my family of 5 to north florida and back and glad I know they will be safe. Thanks guys for taking care of it while I was underway.
We had to replace a tire due to a nail. Luanne was very helpful in getting us the exact tire we needed delivered in a day. After trying to get the tire from another shop and them ordering the wrong tire, and being rude to us, this was a nice change of pace. The guys were able to put the tire on right away. Great place to do business and we'll be back is we need any tire or auto repairs.
Good and friendly service, quick turnover. We are traveling (so out of our home territory) and our Ford F350 Diesel needed an oil and filter change. I called and was told to come on in. Jaime was knowledgable and gave me a good overview of what my diesel needed and why. We are very pleased. (There are also some places near to shop at or eat if you need to wait and kill some time).
