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 Pry Automotive, 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.
Nothing but High Praise for this shop and all of their employees - Family business that provides exceptional service. Drove me home while they worked on my car the picked me up upon completion...

I had a pre-purchase inspection of a used car done at Pry Automotive in Butler. I was helped by Dominic and the service was amazing. My experience was one of honesty and straightforward communication. I live about an hour away and had scheduled this inspection to be done over the phone. Dominic had the vehicle come in as soon as he could, examined it, and called me afterward to give a comprehensive review of the issues and helped me figure out hypothetical costs for repair. This was my first time buying a used car and Dominic gave excellent advice beyond what was expected. I would highly recommend this location.
I heard about Pry from a new neighbor upon my recent move to the area. After having a new battery installed on my Jeep at a different shop, it failed inspection since the sensors had not completely reset, which I have learned is a common problem. I called Pry and explained my problem and John was as professional as you could ask for. He new my issue reassured me that it's a normal occurrence and I have set an appointment to have it repaired and inspected at Pry. I'll review after the work is done, but if the telephone call is representative of the way I'll be treated I believe I have found my local shop for all my car repairs and maintenance.
