During an energy audit, a professional will inspect your home for leaks in the windows, doors, and walls; check the insulation in the attic and basement; and look for other ways to improve your home’s energy efficiency. They may also test your home’s heating and cooling systems to see if they are working efficiently.

A home energy audit is an assessment of how much energy your home uses and how you can conserve energy. The auditor will review your utility bills, do a walk-through of your home, and test your insulation, windows, and appliances. They will then give you a report detailing where your home is losing energy and what you can do to fix it. Most homeowners can save 10-30% on their energy bill by following the auditor's recommendations.
