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 Forest City 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.
Reviews
Very happy with the service. As a full time RV traveler, it is always nice when you meet up with a business that helps you out with a problem. We had a problem with our utility trailer that hauls our motorcycle. Not only did they pick up the trailer they did a complete job in servicing it and then returned it to me. They picked it up on Friday and returned it on Monday afternoon. They repacked the bearings replaced the end caps, replaced 3 tires and fixed the lights. I would recommend this business to anyone in need, no nonsense repairs, what a concept! Chris Kondreck, 10/02/2024 |

I've had some questionable experiences here in the past, but the service I've received this time is restoring my faith in the business... thanks Chance! Geno Lopes, 09/19/2024 |
