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

Dylan's Automotive

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 Dylan'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.

A+ experience and I am critical and skeptical of mechanics. Dylan and his team are very personable, never hesitate to take the time to discuss issues and options with you. Very honest and straightforward and some of the lowest prices I've seen. Couldn't be happier knowing I have a dependable mechanic in my town. Thank you Dylan. Give him a try, I highly doubt you'll ever take your car elsewhere.

I was referred to Dylan's for electrical work by another local shop that I trust. I would recommend Dylan's to anyone looking for fair-priced, skilled automotive repairs. Plus, they are very honest and friendly.

Over a year ago my driver side window regulator stopped working. Brought my van into Dylan's for repair. Last week the new regulator broke. I rarely drive my van. Only driven around 3000 miles in 18 months. Dylan's repaired the window for no charge even though it was a bit out of warranty because of the little use the window had. Thank you Dylan's for backing up your work, and parts!! I appreciate that you took the extra step with my vans window issue. You have definitely earned my gratitude, and loyalty!
