Ac and heating repair service near West Islip, NY

Service fine as always

Dave and his staff at Diamond Auto do exemplary work, honest and done right the first time...always. Never an issue and always on time and often under estimate, I couldn't ask for a more professional and skilled shop. In a world where it is often lacking, Diamond Auto has integrity.

Warning please don’t go to these scammers, they charged me 700 to fix the heat in my car. Then go on to say sorry the heat only works on the passenger side and ac only works on driver side and to fix THAT issue they will charge me another 200 for diagnostic and from there it will be anywhere from 1k to 3k more. All they did was change the heat motor in the car which another Machanic I took it to said would have been 200. To top that off they left my driver side window open in the rain and now my car has a puddle in it. PLEASE be aware of these guys they will scam you I promise.

The service was great, Jimmy was a pleasure to talk to over the phone and even nicer in person. He fully explained what was going on with my car and exactly what they did. The price for all the work that was done on our car was very reasonable. I didn’t feel ripped off like I have in the past at other mechanics. I am very thankful for how quick they were able to have it done considering a few set backs they were having that day in general. I would fully recommend them to friends and family. Dorian Delany
