Replace Your Car's AC Thermal Expansion Valve or Orifice Tube
Friesen's Auto Center
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 Friesen's Auto Center, 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.

While traveling through the Ft. Collins area last Friday, I experienced a problem with the brakes on my camp trailer. I spring had broken and caused my brake to bind up. I stopped on a couple of shops along Collage. One of the shops didn't have time but called Friesens for me. The guys at Friesens said to bring it right over and they could take a look. Once we arrived the guys dropped what they were working on and went to work on my trailer, I knew they were busy as the shop was full of other customers vehicles. Long story short, the guys at Friesens saved our weekend in the mountains. Another great thing is they didn't try to gouge me out of a bunch of money and they were very quick. I have a couple of other projects that need repair and I will definitely take then to Friesens Auto.
