Replace Your Car's AC Thermal Expansion Valve or Orifice Tube
Austin's Tire and Auto
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 Austin's Tire and Auto, 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.

Great, friendly service. My car needed service. I called, and they squeezed me in within the hour. Nice to have a service station you can call and have reliable work done.
These guys are the best! Our a/c went out. 95 degrees, black car, black leather interior, an oven on wheels. Had to get it fixed, had it looked at by several shops. They all wanted at least $1000 to do the work. Austin's did the work for FAR less and even deducted the cost of the original visit to find the problem. Brought it in at 8am and picked it up the same day. So happy with their work, and highly recommend them to anyone with car issues. You can count on honest and quality. Can say enough good things about the guys.
Here on vacation from Ohio and started having car problems. Took it to Ronnie, he checked everything out and made the necessary repairs for a more than fair price. I kind of expected to be treated like a tourist but it was more like going to my regular mechanic at home. Thank you Ronnie!
