FRANKLIN AUTO SERVICE > REPAIR SERVICES > AC REPAIR > REPLACE YOUR CAR'S AC THERMAL EXPANSION VALVE OR ORIFICE TUBE
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 Franklin 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.

What People Say About Us
I was a first time customer and had a great experience. They called me the day I towed my car there and told me what was wrong and how much it would be to fix it. (Needed a new ignition switch). My repairs took a little longer than expected and they were more than accommodating and even gave me a discount. They were honest and genuine with me over the phone and in person. 10/10 would recommend!
Very professional and took the time to answer my questions as well as demonstrated the repairs that were completed.

These guys are great. Super friendly, professional, knowledgeable, share information and answer questions till you are satisfied. It's just a 3 guy shop, but I was impressed with how fast they turned my car around, and I'm happy with how well it's running again.
Seriously the best service at a auto service center that I have ever had. Prompt professional and helped me out in a jam without blinking an eye. I would recommend them for any automotive work whatsoever.
Very polite and honest. Great service. Plan to use again if have any future car problems.

Absolutely excellent experience. Called last minute for an oil change and they fit me in. The owners are super kind and honest. This was my first time here and I'll definitely be back! Wonderful! Thank you
