Windows, Doors and Siding
Your home is one of the most important investments you ever will make, and major home improvement projects often become
necessary over the life of the home.
To help you with these expenses, MidAmerican Energy offers EnergyAdvantage Financing for windows, insulated vinyl siding
and exterior doors through First American Bank. These loans take some of the expense out of home improvement, and the
energy-efficient replacement measures help make your home more comfortable.
Rebates also are available for adding other energy-efficient measures to your home. View our heating,
cooling and water heating information for additional savings opportunities
