ENERGY STAR® window rebates

Improve your home's comfort, efficiency, and value

Drafty windows are one source of energy loss. They also negatively affect home comfort and property value.

If you heat with electricity, you could receive a rebate if you upgrade your home's windows to ENERGY STAR® windows. We offer a $25 rebate per qualified window (both new construction and replacement windows are eligible).

Combine our rebates with federal tax credits! Save 30% on the cost of materials up to $600 per year.
