"Bob inspected the window frames and provided a few solutions I hadn’t considered. Same for interior doors no longer hanging properly. Although I typically prefer paying by the job instead of by the hour, Bob was quite focused on his work and use of time. I will be asking him to return in the spring to complete a few additional repairs and install a storm door."

"We had a salesman out, the call was a bit long. But we used them for a sliding glass door and the install went well. A sash has to be reordered but they are on top of it."

"I emailed them photos. They had to order replacement hinges, which took a while. Fixing the door was a two person job. They were very professional."

"Rob Calnan and his team were really great!  After contacting a bunch of contractors that take part in the MassSave program, we decided to go with Calnan Energy Systems because he could do the job much faster and to a higher level of quality.   
They took the time to explain the details of the project at every step of the way.  They have a bunch of ladders and the best equipment so that jobs can be done with maximum efficiency.  When a few open seams in our sheathing allowed cellulose to blow into the house accidentally, they didn't miss a step and cleaned up everything to a level even better than they found it.  These guys work hard all day long, from the moment they arrive to the time they finish cleaning up.  
I can't speak to the direct impact on our utility bills since we moved in a short time ago and we have installed a new high-efficiency boiler just before the winter heating season began.  However, we do notice a *slight* reduction in street noise.  I have also taken some infrared pictures of the house (both inside & out) on a very cold night in January and it's clear that we're sealed up tight!  No missing cavities due to framing cross-members, etc.  They also blew insulation into a few porch overhang cavities as well.
Since the job ended I have called Rob with a few insulation questions and he's been super-helpful.
I would highly recommend Rob and his company!

"Michael was the ONLY one who responded to be out of 20 different companies when I had a leak from my living room window during a storm in November. Not only did he respond, he showed up in two days and I got the repair done in 3 weeks that was supposed to be at least 6 weeks. I’m so impressed and grateful at the quality of work and efficiency. Will def be asking Michael to replace all of the rest of our windows!!"
