We had a terrific experience with Calnan Energy Systems. Rob was an invaluable resource as we sought out insulation contractors and performed a full insulation upgrade on an old Victorian during a major renovation. Rob enrolled us in an energy savings program, performed the preliminary energy audit, and guided us on what to look for in a top notch local insulation company (since he was unavailable...

Mr. Calnan and his crew did a great job upgrading our attic insulation, which involved several different tasks. Everything was clearly explained to us. The workers showed up promptly, everyone was friendly and polite, and they took great care to clean up after themselves. Recommended without reservation.

Rob was very helpful in assessing how to address our issues with water/air getting through our wall. He was professional, friendly, honest with his quote, and got the job done in a timely manner. I would definitely work with them again.

Great! We have a 140-year old Victorian with third floor knee walls, very hard to insulate. Rob and his sons did a thorough job of applying high R-value insulation between the rafters, so we will have a cold roof to prevent ice dams in the future. Also had old casement windows in the basement that were falling apart, and they rebuilt four windows with new frames that look like cabinet work. Reason...

Rob and his team did an excellent job and worked long days to complete the job within the timeframe expected. They were communicative and explained options to us as they were working. When a few challenges came up they stuck to the originally indicated price and charged only for parts, and not for the additional labor required. I got the sense that he took a real pride in doing an excellent job an...

Rob and his sons did a great job in replacing our home's very old front door with a new fiberglass door. The work turned out to be very challenging and it took full two days (more than originally quoted). His team completed all work very professionally without charging additional labor cost. Billing was clear and as expected (no surprise) with reasonable cost of extra materials. We are very please...
