A.J. Michaels is local and family owned.
Not a franchise or owned by an out-of-town
company 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 wider Baltimore region.
And because we’re a locally-based and family owned company, you don’t have to wade through multiple layers to reach the people you need. Whether it’s a quote, a question or an after-hours emergency, you’ll get through to someone who can help — quickly.


We’ve earned a reputation for successfully tackling the toughest challenges, again and again.
Our mechanics, field reps and technicians average well above the usual industry education and experience levels. Because of our expertise, we’re regularly called in on some of the most difficult heating, cooling and plumbing projects.
We believe in doing it right.
We don’t use subcontractors. When you choose A.J. Michaels, you get highly trained experts from A.J. Michaels — and nothing less. We don’t consider a job finished until our degreed engineer has inspected it.
We believe in being available.
We offer 24/7 emergency service and we don’t charge extra for evenings or weekends.
I have been a happy customer of AJ Michaels for more than six years. They installed my whole house air conditioner about six years ago and they have taken very good care of us over the years. Everyone we have had contact with has been wonderful. This morning one of their technicians arrived, on time, to replace some parts. He did a great job. He is polite, competent, efficient, knowledgeable and friendly. I highly and without reservation recommend this company!
