Replace Your Car's AC Thermal Expansion Valve or Orifice Tube

Raul's Auto Repair

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 Raul's Auto Repair, 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.

Testimonials

Ok, so we all know finding a reliable, trustworthy auto mechanic is like looking for lost treasure: IF its out there, you'll be spending a lot of the time looking. Well Raul's is gold. Raul is the owner and a complete business man with professional service and top quality customer service (and I should know- I work at Nordstrom). I will never go anywhere else. The prices are more then fair and the service is top of the line. I could make a list of all the things they have done FOR FREE. They have loaned me a car, done a diagnostic, checked wiring, picked me up, dropped me off, replaced valves , did research on warranties I could be covered under, EVERYTHING they could without charging me. Last time I picked it up, it had more gas then when i dropped it off. They put GAS in my car and didn't charge me. When does that happen? never. Only at Raul's. I dropped off a 6 pack just because I was that grateful.
