Replace Your Car's AC Thermal Expansion Valve or Orifice Tube

A.G. Automotive & Diagnosis

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 A.G. Automotive & Diagnosis, 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.

TESTIMONIALS

My regular mechanic has been really busy lately, and My daughter brings her Prius to A.G. Automotive, so I decided to try them out, and I was not disappointed. Chuck was very professional, and honest. He did fix the problem at hand, but did say he needed a few days to find the actual deep down cause of the problem so we will bring the car back very soon. He got the car back on the road, and I felt very at ease talking to him. He is very down to earth, and to the point. He is a mechanic you can send your kids or wife to and not worry about getting gouged or sold services that are not needed. Now granted they are a bit short handed right now, but they will get the job done. I feel like I have found a new mechanic, Also Thank you to Amber who answered the phone and got me in.

All around amazing shop!! Some of the nicest and most up front people I've ever met. Aside from excellent customer service, there's no one I would trust more with my car. They got me in quickly and not only fixed my electrical issues, but made sure everything else on the car looked good. They even gave me a heads up on what I will be having to replace next! This shop is a rarity and will forever be my go to.

Chuck was great and he's a wealth of knowledge. AG was highly recommended by my local shop for a transmission service on my Ram 3500. He walked me through the things he looks for and the steps that he takes to do the job right. Doesn't hurt that their price was very competitive too.
