I had these guys perform a home energy audit, and i believe it was well worth it. It was a longer process than i thought, but the information that they showed me really opened my eyes. They didn't just tell me whats going on with my air leakage and duct leakage, but they actually showed me and and asked me if I can follow them as they performed the test. I felt no sales pressure at all but after seeing my duct leakage for myself, i went ahead and had my ducts sealed. I am very, very pleased with their services.
