Home Energy Assessment

For our residential customers in Iowa and Wisconsin

You can cut down on energy waste by adding insulation to attics and walls, air sealing leaks, and upgrading appliances to newer, more efficient models.

Help save energy and the environment by having a Home Energy Assessment. If your home qualifies, we’ll send a certified energy expert to inspect your home. The auditor will identify ways for you to reduce your energy usage, give you estimates on how much the upgrades will cost, and tell you how much you can expect to save.
