“From the initial visit by Mike, to the work done by the technicians, everything was done professionally. I had air sealing and insulation installed in the attic as well as the ductwork encapsulated. The techs also built an insulated sub-attic around the air handlers. The problem I was having was the upstairs second floor was always cold, and the heating system was cycling on and off a lot. Now that the work was done in the attic, you can notice that the second floor actually holds the conditioned air for a much longer period of time. The difference is amazing. Additional benefits include my heating system is not cycling anywhere near as much, which will add longevity to the life of the system and less heating oil and less electricity used, which will lower my electric bill and home heating oil consumption. Mike came out again after the project was completed to “test out” the results to ensure I was satisfied with the job. Bottom line is that I now have an energy-efficient home, which is why I chose to do the project, and choosing Mainline was the best choice because of their professional, knowledgeable and personal service. Mike and the team were outstanding. Five stars – I highly recommend their service.”
