Highest level of overall excellence I have experienced with a heating company. Clear, concise communication, absolute pleasure working with staff. Estimate was in line with final invoice, fair pricing for parts and labor without any sticker shock surprises. Zero upsell tactics, unlike some other companies. Technicians left work areas as they found it, exactly as it was prior to the work performed, clean & tidy. Will certainly hire Northern Lights Mechanical again for any future work and/or maintenance within my home. A+ in my book.

Highly recommended Northern Light Mechanical for any HVAC and Electrical needs. Chris and Maureen are really nice people to work with along with being very professional. Had a heat pump installed and the process was seamless!

- Rich Russo

Chris and his team installed a new propane heater for hot water and an outlet for my new generator. Great quality work and reasonably priced! He also cleans my boiler and does a fantastic job. Very reliable. I’d hire him in a second!

- Phil Napolitano

The technician that came over was fantastic. He was able to explain everything about the boiler, replacement options and other heating systems in a way that was respectful, understandable and helpful. He seemed to love his job and was very professional.

Pre-Christmas our older heating unit had been down for weeks; all the techs that were able to fit us in wanted to sell us a new system… the house was quite chilly. At the 11th hour, we were fortunate to have Chris come by, and knowing Buderus, he got us up and running within a couple hours. Nothing like a warm home on a freezing morning. No need to call anyone else. Thanking Maureen, Chris and all at Northern Lights a thousand times.

Chris and his staff have maintained my apartment buildings with natural gas boilers, maintained and replaced the oil boiler in my home, and installed high efficiency heat pumps in my vacation house. He even set the electrical service on it. Northern Lights Mechanical takes care of all of my HVAC and electrical needs. Always professional and of great value.

- Tim Libby

You couldn’t ask for a better team to solve your plumbing or heating issues or upgrades. They just installed a new hot water heat pump and we couldn’t be happier. Not only was the install flawless but the workmanship and cleanliness was exceptional as well. Highly recommended!
