Ac and heating repair service near Harrison, NY

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.

Friendly expert service and fair pricing. It doesn't get any better than that. I have always had repairs done in a timely manner. Great guys to deal with.

Great work! Very professional and skilled individuals. Luis was a great help very informative, knowledgable, skilled, and efficient even got a free car wash. Excellent work at an excellent price.

DO NOT USE THIS SHOP. charged for repairs they did not complete, lft with damages and the "GUranty" isn't worth the paper it's written on. Shoddy, dishonest.
