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 Fox River 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.

Very busy place but helped us in a pickle. We appreciate you and your hard workers.
We started our vacation off great by arriving at Germfask safely. However, the same night, we decided to get ice cream, and the truck was making a weird noise. We were fearing the worst, wheel bearing. Recommendations from a local store pointed us to Fox River Automotive. I have nothing but kind words to say of Gramps. I've yet to learn his name. Google said he was open. However, we learned differently. Despite being closed, Grandpa took our truck for a ride and advised us of our problems. He even received a phone call from his family telling him breakfast was ready. It's very scary to be 6 hours from home and no way to get around . We are blessed and thankful that Grandpa took the time out of his schedule to diagnose the issue, let us fix it on his property, and a promise to come back after he visits his family from Pennsylvania. His grandson was pretty awesome, too. He didn't have to help at all. He could have simply stated his business was closed and closed the door. May Gid bless this man and young man.
