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 Starks Auto Service, 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.

Imagine my frustration when the car I had just purchased from Carvana was making noises the same day that I received it. Then, having to call several numbers and speak with half a dozen Carvana and SilverRock representatives before being referred to Firestone, only to be told that they don't service Jaguars. After having to speak with several more representatives I was referred to Starks Auto Service. Honestly, I was geared up to be even more disappointed before I called, but upon speaking with Tony he put me at ease. He understood my frustration, was straight-forward, courteous, and easy to talk to. Diagnostics had to be run, and the water pump needed to be replaced. He took care of everything for me so promptly, and I didn't have to worry about a thing. Tony is the man, and I can't sing his praises enough. I'm a new loyal customer, and will always recommend Starks to my family and friends. Thank you, Tony!!!
Starks auto truly saved us when I was 39 weeks pregnant and needed a new radiater. We had brought our two kids in who are absolutely wild, but it didnt matter to them, they were friendly to us and took the effort to put on the channel that would help our kids feel welcome and us parents more welcome as well, it made sense to go back for standard maintenance and to check our (new purchase) old car to see if everything looked good. We plan on making the hour drive for any maintenance from here on out. Welcoming, warm environment and the signs all over about God being in control really makes you feel better.
