I could not have been more impressed with the American Installations assessment from Lukasz, who was extremely professional and went through the entire house explaining everything that MassSave & American Installations could do to save me energy costs. He took the time to explain everything in depth & was able to print out a cost analysis of savings during the assessment which was very interesting. The crew that was sent out was most wonderful, Cody, Josh, and Clint- All very polite, kind, professional, courteous and did an amazing job. They cleaned up the the whole house when they were done & my house was left much more warm and sealed up for the winter. I would highly recommend having a MassSave energy audit and having American Installations come out for your house, my only regret is not having done this sooner!!!
