I recently had ADM Mechanical Service & Maintenance come out for an AC issue followed by a plumbing issue. Both techs arrived at the promised time and were extremely knowledgeable and friendly. I would definitely use ADM Mechanical Service & Maintenance again and recommend to everyone.

The kindness, care and professionalism of the staff is much appreciated. Even though I was a new customer they showed us the courtesy and care that Slomins did not, after 30+ years as their customer. Thank you so much. Call you won't be disappointed!

Called and got Adam to come to the house and fix and issue caused by another team. He was honest and got the job done quickly and efficiently. Would definitely go back for any future issues with my HVAC

Our hot water stopped working last month. ADM determined the problem. They ordered the new pump and came the next day to fix it. They explained all the steps. They didn’t rush. Their office staff answered all our calls promptly. We’ve had no issues with our hot water. We highly recommend them.

Needed my ductless ac ¢tral because they both went down at the same time. Andrew responded immediately and fixed both. Reliable, affordable and great to deal with!

My baseboard heating stopped working for the first time since we’ve purchased this house so I called over to ADM. Derek and Andrew showed up on time the -same day I called- and found and fixed the problem in less than an hour. Super friendly and very helpful highly recommended
