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 Prattville Auto & RV Repair Center LLC, 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.

This is a wonderful business, thought hard about not doing a review because I want to keep this gem quiet, but it's too good to keep a secret. If you want to fix your rv this is the place to go.
We are a little late posting these comments but better late than never. We had the fuel pump on our 2011 Damon Daybreak stop working while visiting the Prattville area in August this year. Kevin and the other folks at Prattville RV provided quick, efficient, and friendly service. We decided to stay a few extra days in the area and then when we got ready to leave the battery on the coach was dead. Kevin and gang had us repaired and on the road within 1&1/2 hours. Thanks Prattville RV for your assistance!! 5 star service.
