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
Pricing is fair and the service is good here. I've been here now 2 times and pleased with the friendly and upfront staff. I don't feel they play games (like at the BMW dealership at Southpoint). I feel comfortable taking my diesel BMW here and did after my friends at work recommended this place.
Great communication! Quick repair at a fair price.
It's heard to find a car maintenance place you trust and auto logic is that for me. They are always really friendly and I can usually get an appointment fairly quickly. They are definitely the best in the area.
Wish I could give them 10 stars! Really friendly, knowledgeable & accommodating when scheduling services but more than anything I appreciated how upfront & honest they were about what services I ACTUALLY needed instead of trying to upsell or coerce me into things I didn't need like so many of the other auto shops in Carrboro/Chapel Hill tried to do. Their prices are also very reasonable and I had my car fixed & back home in less than 24 hours. So grateful there's still honest, local businesses around!
