"Highly recommend. Exceptional and professional service from their contractors and most especially by Nolan Walker (Performance Consultant). Nolan showed photos taken of my home's ductwork and insulation and provided a list of options and the cost of each project so that I could make a well informed choice of which projects to pursue. He took his time and was honest and understanding - not aggressive like other companies I have dealt with. His test-out and follow-up appointment was just as thorough. It was a pleasure working with him."

"Great! Job was complete .... removal of existing 50+ year old insulation, air sealing attic, baffle installation, installed 18 inches new fiberglass blown insulation, and new whole-house fan. Job started and completed as proposed. Crew on-time, quietly performed their work, and left spaces clean when done. Definitely worth the cost as noticeable improvement in second floor temperature and humidity readings."
