Replace Your Car's AC Thermal Expansion Valve or Orifice Tube
All Pro Tune Up Inc.
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 All Pro Tune Up Inc., 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.
More AC Repair Services:
As a retired collision repair specialist I am very hard person to impress when it comes mechanical service on my 2004 Toyota Truck. Four months ago i took my truck to this shop with hot AC. Two good mechanical shops had tried and failed to diagnose problem correctly despite repeat visits. Gerald and his crew persevered and diagnosed the problem correctly the first time, repaired it with high quality parts and returned to me ice cold and good as when bought truck. I waited four months to give review. Still perfect. I have had several occasions since to have other repairs. They are the most meticulous techs in area.They check everything. They keep you informed of status of repairs and have excellent management and technicians to do the work. They do not recommend services/repairs that are not needed. I travel about 1/2 hour to get to them. Well worth it.
