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

All American Auto Electric

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 All American Auto Electric, 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

reviewiconHonest and Professional
Heating and Cooling Services, near Tallahassee, FL

I brought my car in because my AC stopped blowing cold air, so they told me that I needed a new compressor and consenser. They fixed my car quickly, and the owner and mechanic were both very professional. I will definitely come back here in the future because I never had the feeling that were trying to up charge me in anyway.

Fleet General Services, near Tallahassee, FL

Having a fleet of Vehicles we are always in the need of work to be done. Good companies that are reliable and trust worthy can be hard to find. I recently took one of our service vans there to be repaired and they took care of us quickly and at a fair price. I have already scheduled to have another service vehicle to be repaired. We will be taking all of our fleet there for repairs.

Brought my car in with no working ac. Was diagnosed and fixed within the day and works perfectly. I couldn't be more thankful that it could be fixed. Thanks Mr. Rick I'll be back.
