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 Ron & Wayne's Auto Repair 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.

    One word: honest. It is hard to find a good honest mechanic in this area that will good your car for a decent rate and not try to rip you off. They aren't the cheapest but they are very reasonable with their pricing. The manager is also very helpful and straight forward with what he recommends.

    These guys are a class act. My son, who's off in college, was driving through Brea when his car overheated. Because of him being out of town I did a yelp search of close businesses. I saw these guys had a 5 star review. I called them. They had 15 min until closing time, but they dropped everything to help him. Not only did they help him they wouldn't take money from him even though they had significant time and some parts involved. If I lived anywhere near them I'd never use anyone else. This story speaks to nothing but integrity and care for other humans. Great job guy!

    Trustworthy, family owned, legitimate repair shop that won't try to stab you for the "ups and extras". REAL mechanics doing REAL diagnostics, not just plugging in a computer and working from a list of protocols. I don't send family or friends anywhere else.
