Expert HVAC, Plumbing, and Energy Solutions You Can Trust

Your Home Comfort Advisors

At Dempsey Energy, we know that real home comfort depends on HVAC, plumbing, electrical and energy systems that actually work when you need them to. Since 2002, families across Massachusetts have trusted us to keep their homes running efficiently and comfortably, and we’ve built that trust one honest recommendation at a time.

With fast scheduling, fully stocked trucks and emergency services available, we show up prepared and ready to solve the problem. Whether it’s a furnace repair in January or a plumbing emergency on a Sunday morning, the Dempsey Energy team is your go-to North Attleboro HVAC, plumbing and electrical service team.

 

As a Mass Save partner, we help North Attleboro homeowners explore heat pump and HVAC options that qualify for rebates, making high-efficiency upgrades more accessible than most people expect. Select new system installations come backed by a 10-year labor warranty, so you’re not just buying equipment. You’re buying peace of mind.

Our plumbing services and electrical services give you one reliable team to call instead of tracking down multiple contractors. From water heater replacements and drain repairs to electrical work, our technicians explain your options clearly, answer your questions and treat your home with respect.

We proudly serve homeowners across Bristol, Norfolk and Plymouth counties, including Canton, Foxboro, Franklin, Norwood, Wellesley and the surrounding communities. Family-owned and locally rooted, Dempsey Energy is the neighbor you can count on to get it right.
