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 Ridge Auto and Tire, 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.

I wandered into this place by accident. I needed a tire patched and saw that the bays were open so decided to stop in. Normally I would have nothing to do with this Delta station, but I think it's important to note that Ridge Auto and Tire only rents the bays from Delta, they're not under the same management. Anyway, they've renovated the inside, it's quite nice. Mo and his people are professional, friendly, on the level and quick. They were nice enough to patch my tire on the spot. A few days later I brought the same car in for other services and they were great. I'm biased because they're right around the corner, but I've definitely found my mechanic. These guys used to be in Bedminster but recently relocated to Ridge. I highly recommend them.
