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 Green Machine Automotive, 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.

Very pleased with all the hard work from the guys at the shop. I needed major work done (engine problems) on my 2006 Dodge Charger. A family member recommended Green Machine Automotive in Seaside. Now days your vehicle is a vital part of your everyday life. Knowing that I needed major work done on mine, I was careful on what shop/ mechanic to entrust my vehicle to and know that the work needed would be done in a timely manner and efficiently. Well, I couldn't have chosen a better place. Andre took his time inspecting my vehicle and listening to all my concerns to better understand the issue. Once he pinpointed the issue, he explained everything very clear and in a way that I would understand what was going on and what the process would be to complete the repair. Any concerns I had, he was quick in giving me an answer, allowing me to feel more at ease that my vehicle was in good hands. Thru the process, Andre reached out to communicate any additional problems that he encountered or to let me know about additional parts that were needed. Very much appreciated because I was aware of everything that was being done to my vehicle. Thank you to Sabino for lending a helping hand. Ernesto, at the front, was friendly and made sure that I had been told about additional charges. He was very helpful in explaining to me the invoices and all the charges. The entire repair was completed in a timely manner. Will definitely continue on bringing my vehicle to Green Machine Automotive for any future repairs/ preventative care. Thank you for all the hard work, greatly appreciated.
