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 Hale's Diesel & Auto Repair, 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.

What Our Customers Are Saying
I know this this the best place we have had our truck in any shop. They have done everything that we have asked them to do. The work they have done for us was clean with no hanging loose wire. While servicing our rear differential in our F350 they seen the gears noticed that the differential gears had irregular pattern on them and sent me pictures so I knew for my own eyes. They answered all our questions and I know they had to get tired hearing our calls but they answered them.

I can’t say enough good things about this shop. They were honest with me from day one and treated me with respect throughout the entire repair process. They took the time to explain everything clearly, kept me informed, and never made me feel pressured or taken advantage of. What stood out the most was how understanding and genuinely helpful everyone was. They knew how stressful it was to be without my truck, and they went above and beyond to answer my questions and make sure I felt comfortable with every step. It’s rare to find people who care as much about their customers as they do.

I am certainly glad I found this Shop, Jason, Brandon, Dustin and Amanda are amazing people. I took my truck in for repairs, and I told Jason that I wanted it checked out from front to back and top to bottom and everything fixed and that's exactly what he did, I was always informed of what was going on with it over there! I had a choice whether or not to buy a new truck or invest in repairing mine and after talking with a couple of my friends that buy a new truck every two years the choice was simple to me. After asking Jason every question in the book, he delivered an answer that made me comfortable with moving forward.... To anyone else over there that put your hands on my truck all I can say is thanks to you too. TOP NOTCH FIRST CLASS THESE FOLKS KNOW THEIR STUFF!!!!!!!!!
