Replace Your Car's AC Thermal Expansion Valve or Orifice Tube
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 Corey's Automotive Repair & Service, 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.

Super friendly staff
Car & Truck Care, near Gas City, IN
Waited almost 3 weeks for another company to not even touch my vehicle. Had a co-worker that referred CARS. Pulled it home and not only did Corey's guys come and tow my vehicle to his shop they had it done 3 days before I needed it. Highly recommend.

These guys answered my call before they were officially open, towed my truck in some of the crappiest weather and road conditions and had me rolling two days later. Fast, professional service at a VERY reasonable price. I did have an issue with something they repaired after I picked up the truck, but it was past their close time, and no one answered the phone. However, Corey did call me back later that evening, but I had fixed the minor issue myself. I feel like my scenario is 1000% the exception of their norm and i would be the .001% of an issue after repair. Also, had i been local (this truck is based in Ft. Wayne, but broke down in Elwood, and had to be on a job the next day) I am 1000% positive that Corey would have made everything perfect, had i given him the chance. I hope to never be broke down again, but if I am, I hope it's around this shop.
