Replace Your Car's AC Thermal Expansion Valve or Orifice Tube
Stop and Ride
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 Stop and Ride, 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.

Stop and Ride was recommended to me by Randy Massey of Neighborhood Paint and Body in Jefferson after my car started acting up. The staff were friendly and professional. I had shown up and decided to wait while they diagnosed the problem. They initially said it would be about 45 minutes, but after about 30 minutes, one of the staff (sorry, I didn't get his name!) told me that it was going to be longer. They even offered to drive me home. About 2 hours later they called me and told me what was wrong, gave me an estimate and told me they'd be done in about an hour. Exactly an hour and six minutes later I arrived to find my car running perfectly.. And the quote they gave me over the phone was exactly what they had charged. I will definitely be a return customer. I've been looking for a good, reliable auto mechanic ever since I moved to Jackson County, and it's a relief to know I've found one. Thank you, Stop and Go!
