Smog Testing vs. Emissions Testing
Many customers confuse smog and emissions testing, thinking they're the same, but they measure different things. Smog checks and emissions tests assess various levels of hydrocarbons, oxygen, carbon monoxide, and oxides to determine a vehicle's impact on the environment. Discover the difference between smog testing and emissions testing.

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.
