"After receiving bids and talking to other pros on we chose Northeastern Mechanical. My wife and I are extremely happy that we did. Our 100 year old historic home needed to be upgraded to modern times and green efficient heating and cooling products. The installation was professional and clean. John was on the job from start to finish. This man is personable and has a passion for his work. You should see the quality job he did. We found him dependable and committed to our job from start to finish. He can also help you with design ideas. His prices are more than reasonable and I guarantee he will not disappoint. I have already recommended him to family members, which I rarely do"!
