Fire Protection

A Family Company

Celebrating 50 years in Business

From our humble beginnings as a local contractor in The Berkshires run by the Dobbert family, The Dobbert Companies has evolved into one of the leading mechanical contractors in Massachusetts.

In 1974, Eleanor and Tom Dobbert launch Dobbert Heating & Air Conditioning in North Adams, MA, with a focus on the same trades as we work in today: fire protection, HVAC, plumbing, and sheet metal.

Building the Foundation


The Berkshires evolves into a hospitality and arts hub, and Dobbert develops a specialty in these markets starting with Mass MOCA, the world’s largest contemporary arts museum (that takes over Sprague’s manufacturing facilities in North Adams). The company rapidly adds many notable clients in these arenas including Miraval (then Cranwell Resort), Tanglewood, and The Red Lion Inn.

Navigating Choppy Waters


Jimmy Dobbert, the brother of company founder Tom Dobbert, joins the company as the lead foreman in the mid-1990s, professionalizing our field operations. He remains with us to this day!

Spreading Our Wings


Having worked with the Dobbert Companies for many years, we are always impressed with their professionalism and response time. The whole team is exceptional to work with and we can always rely on their expertise and dependability to get things done.

– Richard Melville, CEO, Five Star Properties

I was at Mass General Hospital with one of my siblings who was undergoing surgery and I got a call that the boiler went down at The Chicken Box. It was during a winter storm and your CEO Mike Dobbert was at our door himself within an hour to make sure that the boiler was fixed so we could keep our doors open. Talk about customer service!

– Rocky Fox, Co-Owner, The Chicken Box

We have been working with the Dobbert team for years. They are reliable, professional, friendly, knowledgeable, and prompt!

– Cathy and Ralph Vizzari

The Dobbert Companies consistently shows up for our clients’ HVAC and plumbing needs. Their communication and response time is unmatched. We are grateful for their continued partnership and dedication to any project big or small.

– Dwyer Maloney, CEO, Main Street Construction

We’ve worked with The Dobbert Companies for more than ten years and they’ve helped us with our fire sprinkler, HVAC, and plumbing needs on dozens of commercial and residential projects. They excel at complex, fast-track, and challenging projects. It’s a great experience working with their entire team.

– Scott Andersen, CEO, The Andersen Company

Can’t say enough about a large group of humans you can trust and depend on in brutal situations. Whether it’s new installs in historic buildings, or emergencies on weekends and holidays, they’ve always been there for me, through the sand and the mud!

– Nathan Skerritt, Director of Operations, Nantucket Island Resorts

We have worked with the Dobbert team for years. We always appreciate their prompt service and attention to detail, especially with the discerning clientele we serve at Lola 41. They helped us on many occasions with our plumbing and kitchen exhaust systems, and have kept our operations running smoothly so that we can focus on providing a great customer experience!

– Mark Daley, CEO, Lola Hospitality 

The team of knowledgeable professionals at The Dobbert Companies instills confidence that your job will be done correctly and in a timely manner. Their fast response times are pretty much unheard of on Nantucket!
