Our owners, Gary and Peggy Doty, have been serving the home comfort needs of the Greater Lansing area for over 33 years. They were the founders and original owners of A-1 Mechanical. After selling A-1 Mechanical and a brief retirement, at the encouragement of former customers, employees and business associates, they re-opened their doors in 2004 as Doty Mechanical. Located in Lansing, MI, Doty Mechanical employs highly trained people whose goal is to make our company the best Heating and Air-Conditioning company in Lansing & Mid Michigan including Ingham, Eaton, and Clinton Counties.

No one likes when their heating or cooling system isn't working properly, but no matter how well you maintain your system you may have to deal with a repair issue. Our office is open Monday through Friday from 8:00 am to 5 pm and someone will be available to personally take all repair requests during that time. After hours? Don't fret. If you call in during the week between 5 pm and midnight or during the weekend between 8 am and midnight, you will be directed to a technician who is standing ready to assist you.

Our a/ c went out last night. It was hot! After four phone calls this morning, I finally found someone who knew about geothermal heating and cooling. Brent came out TODAY and fixed the problem, for way less than I expected to pay! He was professional, knowledgeable, and not intimidated by my brother-jn-law's crazy barking dog. I'm so relieved and grateful to have found a resource that I can call in the future!

The technician arrived at the very beginning of the time estimate and called before arriving. He was very friendly and explained well what needed to be done to fix our AC. He was done within half an hour and made sure to follow up with a phone call to check that everything was still working well a few hours later.

Great service! Great value! Doty came out and went over and above the call of duty on my furnace replacement.
