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 Seasonall Automotive Center, 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.

I have been taking our cars for every type of service to Seasonall for the last 30 years. I have never had a single problem with the work done. Quality service at an excellent price. Mechanics you can trust. The best repair shop I have ever used.

My wife and I purchased a vintage 1969 Shelby GT500 in July, 2017. Having worked as a Ford technician over 40 years ago I now these particular vehicles inside and out. But, at my age and medical condition it is hard for me to do much more than tinker with it. I called a lot of shops in the Rochester area that were recommended to me. This the only repair facility that sounded eager to have the chance to work on this awesome vehicle. I was very pleased with the work they performed. Not only was the work excellent, but they were willing to listen to my special requests. Lucky us to have found them!

I've been going to Seasonall for years and I wouldn't go any where else. They took care of my 1998 Neon until I got a new car in 2012. I have recommended them to friends who are also pleased. Have them work on your car; you won't be sorry.
