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 was in a bind on a cross country road trip and this place really turned the tides. Had two shops back to back leave me with a mess and frustration to fix on a 2005 Chevy 3500 Duramax turbo replacement til I found this place. Gave them as much info as possible to help gain a full picture of the status of the vehicle, and handed them the keys. First, they stunned me with volunteering to pay for a ride to the car rental lot. Next, sent a very thorough vehicle report and delivered a clear phone call with recommendations, further diagnosing some things I had not been able to and helping me understand the process. Got everything back in short order and hit the road. I am genuinely happy with the services rendered here and am reporting on a healthy truck that has handled considerable miles and grades across the country since. The Hale's are educated professionals at running their business, and their mechanic at his trade here. I also received a follow-up phone call checking to make sure things were going well. Thanks again.

Needed a 100k checkup on my Duramax. They got me in and out in reasonable time and at a fair price. Went over the entire truck and let me know what needed fixing. Gave me option to approve recommended repairs. Would definitely go back.
