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 Auto Logic, 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
Everything about my experience was fantastic. From the customer service to the speed in which they had my car finished, it was exceptional from start to finish. I would highly recommend them to anyone and everyone I know! Dealing with Auto Logic was a breath of fresh air after my experience with other auto shops in the area.

Used Auto Logic (AL) to examine a Toyota I was purchasing from Carvana. Easy to make an appointment, AL explained what they would do ahead of time, kept me updated during the process. Only complaint is I wish they had more space over on Main Street in Carrboro!

Highly recommended! I had an excellent experience at Auto Logic. I have visited seven shops in the area over the last few years. Auto Logic and one other shop stand apart compared to the rest. I cannot comment on the high costs that other customers mention. However, the service they provided was well worth the cost in my experience. I spoke with Daniel at the end of the service, and he was very helpful. The summary of the issues and his explanations of them made me feel confident in the shop. I felt comfortable asking for him to explain the issues more so that I could understand better and make the right choice for me.

I appreciated the way they were able to diagnose my truck's air conditioner issue. It has been running fine since I had it taken In and seen to. In this weather it is a blessing. The communication was very informative and helpful. And I especially appreciate that even though they had a very full list of people with appointments, I still was able to have the truck analyzed because of MaryAnne's courtesy in recognizing that the schedule changes during the day meant they would have time to look at it. That was also a blessing.
