Replace Your Car's AC Thermal Expansion Valve or Orifice Tube
Fletcher Car Care
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 Fletcher Car Care, 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.

Great place for car care. Very professional and clean area to wait. Highly recommend
Great place! Thanks for taking care of me today. Will definitely recommend to others.
This shop is top-tier. The services rendered, over the course of 6 years for my family and I have always been exceptional and thus far without mistake or slack. Always professional and down to earth, and desiring to be helpful and informative. And clear. And, importantly--HONEST! I'm a transplant from NJ and we had a similar great neighborhood auto mechanic business (shoutout Bill's Ineffable Automotive Rehabilitation in Metuchen) but that's neither here nor there. Fletcher Car Care is worth trying out!
