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 Johnny's Automotive, 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 would highly recommend Johnny's Auto. They were very friendly and got us in the next day. They explained everything in great detail and when we left there was a rose on the dashboard.

Johnny's checked my starter thoroughly and found nothing which was very reassuring. Since nothing needed repair, I wasn't charged a dime for the service which means that Johnny's is truly a reputable auto maintenance repair shop that isn't after gouging anyone that brings their car in. Honesty and integrity is what Johnny's stands by. I will share this experience with our community's Next Door. Johnny's keeps earning five stars!
