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 De Anza 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.

Went here to fix my Turo car. April had been very helpful through and through! She helped with the insurance process and has made it seem less for me. Would recommend and come back again!
April was very helpful to my daughter and her Porsche, Boxster. So, when my Prius had problems, I knew who to turn to. It turned out to be a serious problem (head gasket) and both April and Mo's brother John were sensitive to the many issues a retired older person on a fixed income has. They still provided excellent service, treated me with respect and worked with me to find a mix of what I could afford, without compromising the necessary repairs. I felt like I had gained family by the time I got my car back. So, when our Lexus had problems and left me stranded in Auburn, California, I knew who to call -- April worked with me to get the engine codes, run them through her mechanics, determine where I could go locally to find out if it was safe to drive it home and April kept checking up on me -- her last call was well after their closing hours when I had been cleared and was driving it back to their shop. I feel like they really care about people they are not just fixing cars. I am a customer here for life.
I recently had my car serviced at De Anza Auto Repair and I was extremely impressed with their honesty and fair pricing. The customer service was phenomenal, with the staff being friendly and knowledgeable. They explained everything to me in detail and even gave me some tips on how to better maintain my car. Overall, I highly recommend De Anza Auto Repair for their exceptional service and great prices.
