What are typically the most cost-effective improvements that can save energy?
It depends on the home. Usually, near the top of the list are sealing gaps, cracks, and other leaks that let outside air into your home (especially in the attic), adding insulation in the attic, sealing and insulating air ducts that run through attics or crawlspaces, and repairing or replacing old or poorly functioning heating and cooling systems and appliances. BrightHome offers all of these services, including the cash back benefits through Home Performance with ENERGY STAR® program.
