What to Expect from a Home Energy Assessment

Customer service assistant working in office

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 or will call you at your scheduled time and will begin your Assessment. (Virtual takes 90 minutes and in-person can be up to 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.
