About Us

A.J. Michaels is local and family owned. Not a franchise or owned by an out of town business or a utility conglomerate. 100% of our income stays in the local economy, enabling you to get the highest standards of workmanship at a price you can afford. When you do the job right — especially the tough jobs – word gets around. Since 1978, we’ve been building our business on referrals from satisfied customers throughout the Baltimore-Annapolis area. Michael Giangrandi, our president, has led the company from Day One. Our mechanics, field reps and technicians average well above the usual industry education and experience. Because of our expertise, we've been called in on some of the most difficult heating, cooling and plumbing projects: from churches to cruise ships; from factories and offices to homes that supposedly can't support central air conditioning. We're here for you seven days a week with no extra charges for nights or weekends. So what can we do for you?
