I am a former ASE certified technician who ususally does most of my own maintenance, however I lacked the equipment needed to diagnose some AC issues with my wife's SUV. I found Rational Automotive online, and the reviews made me feel comfortable enough to trust my vehicle with them. Paul up front was very friendly and straightforward, but best of all, he was honest. He could have easily sold me any number of major components associated with the AC system, but he said they found a small leak at the service ports and had me blowing ice cold again for a couple hundred bucks(diagnosis included). I highly recommend Paul and Rational Automotive and I will be bringing my Acuras here in the future for anything I can't handle on my own. 5 stars!
