Replace Your Car's AC Thermal Expansion Valve or Orifice Tube
Rick's Automotive 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 Rick's Automotive 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.

I was here about a month ago. Had an intermittent starting issue with my Honda for a few months that couldn't be determined. My starter finally gave out and I had to have a tow on a Monday morning. Rick's was the only place of 3 that I called that could look at it the same day (the other two gave me an eta by the end of the week). He confirmed the starter gave out same day and had the repair completed at the end of day on Tuesday for me to pick up. They took the time to answer any concerns I had during the process. I will definitely be a returning customer for any future work.
