Cannot recommend enough. Came out during the lions playoff game and fixed my furnace. Vinny is a magician. He is extremely knowledgeable and was able to fix a problem (seized inductor motor and ball bearing housing) like he was working on his own house. 10/10 for service and walking me through what was the problem.

Doty was fantastic with the build out of new laundromat! From planning phase, to working with energy company, to working with me to save costs, to final inspections they always gave 110%. I would recommend Doty for both big and small projects, you won’t be disappointed!
