Gas Furnace Installation in Brewster, MA 02631

September 30, 2026

“We have chosen Northstar twice to handle heating issues . They were always prompt, effective and more than competitive in cost. Our most recent installation was complex and involved several days of labor. The team of Ava, Zach and Joe were outstanding in their work and installation. I would hire them with total confidence because of their professionalism, honesty and diligence. After Ava took over for Joe she helped us understand what was happening every step of the installation and managed complex problems with total professionalism.”

Boiler Repair in Eastham, MA 02642

August 17, 2026

“Can’t speak highly enough about the recent service we received from the team at Northstar when our water heater and parts of our boiler failed, leaving 1/2 inch of water on our basement floor. They responded quickly, diagnosed the problems and most importantly expedited the repairs. Chris and Matt also upgraded the piping around the boiler and hot water heater by adding a number of new shutoff valves so that if problems occur in the future we can just shutoff the affected parts of the system without having to shutoff water to the entire house. They were a pleasure to deal with and I would highly recommend them to anyone!”
