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 Circle Automotive Inc, 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

I was involved in an accident, and Circle Automotive was called in to tow and store my vehicle. For 2 months I have been back and forth with 3 different insurance companies and Circle Automotive has been a GOD SEND. They have been amazingly helpful and patient - not only offering guidance but also HELPING me get the insurance companies to move. I really cannot say enough and will DEFINITELY be using them as my repair shop once I'm back behind the wheel! THANK YOU SO MUCH CIRCLE AUTOMOTIVE!

I wish I could give a MILLION STARS. Police called for a tow. I was rescued by the owner of CIRCLE AUTOMOTIVE during the storm of 1/23/16 At 1AM off of Route 1. Not only was I rescued, He was GOD SENT, HONEST AND KIND considering the weather. I wasn't ripped off. The owner and his employees took GREAT care of me and more importantly, my Madza RX8. I pray never to have to be rescued again, but if I have to I will call them. I recommend anyone who is in need to call them too. MANY, MANY THANKS!
