John is the best mechanic I have ever gone to. Not only is he knowledgeable but his shop is clean with all the latest equipment. John's prices were fare and he got the work done in a timely manner so that we were back in the road ASAP, which was oh so important since it was our work truck so no truck no work. I highly recommend John especially since the other mechanics we have used in the past were nightmares. John has the experience to make having your car or truck "in the shop" not a worrisome event. He will do his best to get you back on the road with your vehicle in better shape than it has ever been.

I was a little unsure of this place since both reviews were very new, but my son's air conditioner died, and I'm only here for a few days getting him settled for school this year, so the repair needed to happen fast. John responded right away to my call, was able to get us in the same day, and had a diagnosis and written quote very quickly. Prices seemed very reasonable to me. Dropped the car off at 1:00pm, and was able to pick it up the next morning. Needed a new compressor, but the car is 21 years old, so not too surprising. Working great now! Very clean shop. Hopefully I won't need service anytime soon, but I'll definitely be back if I do.

This is a one man shop that is well equipped and the owner, John is very knowledgeable. He got us fixed up in nothing flat. He is able to do just about anything. His shop is spotless and full of all new equipment. He has all the tech savvy on line stuff. Don't let his location scare you off, once inside you will be very impressed. This is much more than an A/C repair shop.

Being an out of town guest in Tucson in the middle of summer isn't a picnic when the AC goes out in your vehicle! I had absolutely no idea where I was going to find a reputable, reliable, and credible individual that ran a shop which included awesome diagnostic tools and up-to-date technology.Fortunate for me and my husband we found Buddy's Auto Diagnostic and Air Conditioning Service. "Buddy" provided great customer service, fixed the issues, and by the next morning we were on our way. The cost you're wondering?? We were not gouged as a lot of places do routinely. We were treated with great fairness .This individual (John Colalillo) has integrity, he's honest, easy to talk to, and his knowledge base is packed full....I believe he would be worth his weight in gold. Can't say enough about him, this is a real genuine guy. We live 2.5 hours north, but we feel so strongly about how "Buddy" runs his bushiness, we would absolutely drive out of our way for him to take care of our vehicles.
