FRANKLIN AUTO SERVICE
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
This is a small family owned garage and I told the mechanic who I also believe is the owner what I desired to have done on the vehicle and within a few minutes he called me back with a very detailed estimate on costs and even contacted my husband and myself to explain a newer, much more gentler procedure for a transmission flush instead of drain and fill being that we were concerned with the mileage a transmission drain and fill would be less likely to mess up the transmission down the line provided the flush the way it had been done in the past could almost be guaranteed to cause expensive transmission work down the line. Our car runs so much better now. Thank you Franklin Auto Service.
Excellent courteous prompt service.
Friendly service. Brought in an old car for inspection. Darrell took the time to explain what was wrong and what I should fix in order to feel safe driving it. They even managed to save the calipers on the brakes, which saved me some money! Thank you!

Darrel and his team did a great job on my car. Very professional, expert knowledge, top quality, all with the added benefit of small town personal service.
Franklin Auto got my vehicle in right away and had an axle replacement, battery, and other items done in same day. Great communication and great service. Highly recommend!
Friendly service. Josh took time to explain car issues with me. Definitely would recommend them!
