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 Perez Tire Auto Care, 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
Let me start by saying I could not be more satisfied with the service that I received at Perez Auto (Formerly Exhaust Pro). I had them redo a brake job that had been previously done by another shop that was a complete failure and this other shop wouldn’t even recheck my brakes when I told him something was just not right. So much for using them again for anything. Anyway, when I explained what I needed at Perez., They were more than happy to look at my brakes and try correct any problems, which they did . It turned out that I needed my original calipers and piston assembly replaced that was not done at the previous shop. My truck had over 500,000 miles on it and these were probably the original calipers. Jason, at Perez, couldn’t have been more Professional, if he tried. After he completed the right job, he took it out for a test drive, and felt like something still wasn’t right and went back and rechecked his work again, and found that one of the new calipers was defective, ordered a new one and replaced it, test drove it again, and everything felt OK to him. It has felt completely OK since driven it by me. Jason‘s attention to detail and his expertise was exemplary. I’ll finish by saying that it was worth every penny and driving 30 extra minutes to get to Perez instead of using another shop closer to my home. I have already recommended Perez to some other people, including my son-in-law, who has already had two brake jobs done at Perez and also has been been completely satisfied. I wish I could’ve given them more than five stars, so I guess this testimonial will have to do. Again, thank you Perez for your excellent service. As Arnold Schwarzenegger used to say “ I’ll be back”.
