Gaithersburg Home Energy Assessments

How Much Could You Be Saving?

With energy prices rising, now is the time to make your home more energy efficient. When you schedule a home energy assessment with Jack Lehr, we’ll send a Building Performance Institute (BPI) certified energy analyst to your home to perform tests on your heating and cooling systems and to determine if any air is leaking from your home.

Once your assessment is completed, we’ll recommend any energy saving measures you can take—such as duct sealing, air sealing, and more. Your utility company will reimburse you $150 or $250 depending on the type of heating and cooling system you have. If you choose to implement our analyst’s recommendations, you also could qualify for additional rebates. We’ll then repeat our assessment post implementation!
