How to weatherize your home

posted on 1/21/2026

Does your house have a draft? Do you fear looking at your heating bills?

You may qualify for a free energy audit through the New Hampshire Home Energy Performance (HEP) program. This program is a comprehensive approach to optimizing energy efficiency and comfort in your home. 

When you sign up and qualify, you will receive an email to schedule a free home energy audit. Your auditor will test your home's insulation and look for any problem areas. Then, your utility-approved contractor will prepare a detailed work proposal outlining all recommended improvements and available incentives. Once approved, the scope of work will be installed. Then a quality control inspector reviews the project. 

This program covers up to 75% of project costs up to $6,000. 

If you are an Eversource customer and your household income falls at or below 100 percent of the State Median Income, you may qualify for an enhanced version of the Home Energy Performance offering. The Home Energy Assistance (HEA) program covers 100% of the cost to weatherize.

To apply, you will need your home's conditioned square footage and one year of heating fuel usage history.
