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 Precision 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
Could not recommend Precision Auto Repair enough! John and the team are incredibly friendly, professional, and communicative. They thoroughly explain everything (which is huge for me because I know nothing) and always offer service options. So glad to have a garage I can wholeheartedly trust.
Professional 100% satisfaction with the work nice and clean owner respect and professionalism
If your car needs work call John at Precision. No nonsense quality work. I couldn't be happier with my repair.
I had a check engine light and I brought it into the dealership. The dealership quoted me 2x the standard price for parts and labor so I called around to get another quote (probably 5 auto shops). Precision was the 5th place I called since no one else was able to get back to me quickly. Precision sent me a reasonable quote within minutes. When I arrived John Rodriguez was extremely friendly and said they could turn it around in less than a day. I barely ever leave reviews but I felt like I needed to for Precision Auto Repair. They honestly made my day so much better after getting no help from other shops that were closer to where we are staying. We are from out of state so we don't have a regular auto shop in SF. But if we did live here, I'd definitely bring my business to these guys. Really appreciate it!
