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 OKG 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.

Cleveland is hands down one of the best mechanics I’ve worked with. He’s honest, knowledgeable, and takes the time to explain exactly what’s going on with your car so you’re not left guessing. I never felt pressured into unnecessary repairs, and his pricing was way more than fair. The work was done efficiently and my car is running perfectly now.

Clevland is hands down the best of the best when it comes to cars. As a woman who knows nothing about cars, I’ve had so many bad experiences with mechanics and shops. Clevland’s professional, honest and trust worthy. He’s fixed 4 cars of ours now and we will never go to anyone else. He’s quick, efficient and I never have to play the guessing game of do I really need this done. From a 79 jeep to my Honda that Ive caused a lot of wear and tear over the years, he’s fixed it all.
