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

Camco Tire & 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 Camco Tire & 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.

What Our Customers Are Saying

Can't say enough good things about this shop. The owner was very nice and accommodating. I needed to have my brakes fixed in 1 day and it was ready in 1/2 a day. You can tell he enjoys what he does and it shows. I highly recommend taking your car here for service.

reviewiconAccommodating, Reasonable, and Capable!

Just before Thanksgiving and vehicle failed inspection due to electrical/wiring issue. Called and my vehicle was taken in that day and fixed within an hour. Cost was very reasonable and everything was explained. I actually live 30 minutes away but to find a business this accommodating, reasonable, and capable is well worth the drive. Thanks again, Mark!

Mark and the technicians as Camco are really great to work with. They have maintained several of my vehicles and I have never had a bad experience. From new tires to radiators, they provide great pricing and solid work. I had priced something out at another shop and Mark beat it by about 30%. I highly recommend his place. One really nice thing is that Dunkin Donuts is across the street (as well as lots of places to shop) and if you choose to wait with your car you can actually knock out a bunch of errands.
