What to Expect from a Home Energy Assessment

We’ll work with your utility provider to get approval for the Home Energy Assessment. If we need more information from you for the approval, we’ll call you within 24 hours.


Your Home Energy Specialist will be at your home at your scheduled time and will begin your Assessment. The assessment typically takes between 2-3 hours.

You will learn how your home consumes and loses energy and you’ll receive a custom home energy report, along with other recommendations to save like insulation or air sealing upgrades.
