The DC Department of Environment is offering free home energy audits through its Home Energy Rating System (HERS) program, which identifies a home’s energy deficiencies and provides homeowners with cost-effective, energy improvement recommendations. The HERS Program will send a RESNET certified Auditor to evaluate a home’s existing energy condition, including walls, floors, ceilings, windows, doors, hot water heating, heating and cooling mechanical systems and other related aspects. Once the home audit is completed, a detailed HERS improvement analysis report is provided to the homeowner with recommendations ranging from no-cost behavioral changes to major improvements to reduce energy loss in the home.
