America's Best Energy Team, Falls Church

America's Best Energy Team can help clients see stars—ENERGY STARs, that is. A subsidiary of award-winning contracting company North Virginia Roofing, America's Best probes residences with all manner of diagnostic equipment to determine the building's energy efficiency. With blower equipment, they check to see if doors leading outside maintain an airtight seal and seek out air-leakage sites. Beyond diagnostics, they can also work to seal air-leaks and add insulation by installing new windows, re-caulking, installing weather stripping on doors, replacing old siding, sealing leaky floors and holes in ductwork, and updating outdated heating and cooling systems that still run on hamster power.
