The work was done efficiently and professionally. The crew was great; they educated us on all things A/C. The office staff has been and continues to be very polite, understanding and very helpful. We highly recommend Heinanen Engineering for your HVAC needs.“

“Great work, very fair prices. Ben was easy to deal with, and his crew did great work and took measures to keep everything clean. We had a 2005 HVAC that we replaced with a nice upgraded system that's working great with the current heat wave. I'm very happy with what we got, and equally happy that we went with B's for the project.“

“Thank you McGraw Mechanical for always being there to help out with any situation that may arise! Awesome work! Friendly and knowledgeable! From South Lyon Woods crew“
