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.

what our customers say

We've been using Johnny's for about 5 years on a few different vehicles. They have always treated us right and their prices are great. I always feel I'm getting an honest answer and not a sales job. We are glad to have found Johnny's for all our vehicle's needs. Thank you

I took my car to the Nissan dealership for a problem that should have been a quick fix, they tried to tell me I needed a service I knew wasn't necessary. I took my car to Johnny's, they looked at it, took a picture of the issue and fixed it in 15 minutes while I waited! They are professional, thorough and super friendly. I won't be taking my car back to the dealership.
