Home Energy Assessment

Discover new ways to save

Do you want to make your house more energy efficient and comfortable, but don’t know where to start?  Don’t worry, that’s what we’re here for! The Home Energy Assessment is an essential step in determining how your house is functioning, what’s working and what could use some improvements.


Your Home Energy Assessment will be scheduled at your convenience. It is an in-depth assessment of your home’s energy performance. Our Energy Analysts are certified by the Building Performance Institute (BPI) or RESNET’s Home Energy Rating System (HERS), and are equipped with state-of-the-art software and technology.

Your Home Energy Assessment begins with a few questions about your home,  includes a review of your energy bills and continues with:

    • A “crawl through” inspection of insulation in your attic, crawlspace and just about every other nook and cranny where energy sneaks out
    • An infrared camera to search for hot and cold spots inside walls, around windows and below baseboards
    • A blower door test to depressurize your house and find the hidden air leaks
    • A safety test of heating and cooling equipment; including carbon monoxide levels and combustion appliance back-draft testing


Your Home Energy Advisor will use the measurements and tests they performed to generate an on-site custom report for your home. Your Energy Advisor will go over the results with you and provide guidance on steps you can take to make your home more comfortable and save on your energy bills.


Special note for Xcel Energy customers: The full-scale Home Energy Assessment outlined above and valued at $400 is available to Xcel Energy customers for only $100!

Do I really need a home energy assessment? Can I skip this step?

The home energy assessment is NOT required. You can elect to start with a free phone consultation or a free estimate. However, many people choose to start with a home energy assessment. With a professional assessment there’s no guesswork. It helps us pinpoint how to reduce your home’s energy waste and improve your family’s comfort. It’s all spelled out for you in a custom report.

How long does it take?

A home energy assessment usually takes 2 to 3 hours, depending on your home.

How soon can I get my home energy assessment scheduled?

A 401(e) representative will contact you within 3 business days to set up your home energy assessment. An assessment time can take place within 1-2 weeks upon receiving your application. Your home energy assessment custom report will be sent to you 1 to 3 days after your assessment. When you commit to taking action on the recommended improvements from the report, we can send crews to your home in 1-3 weeks, generally.

Is there any commitment when I apply?

No. There’s no commitment when you apply. If you’re accepted, your 401(e) representative will contact you to schedule a Home Energy Assessment. Based on the results, they will present you with a custom proposal that includes a cost estimate and financing options. At that point you can decide whether to have your energy improvements installed.

What is a blower door test?

A blower door test is performed to determine how “tight” a home is. A blower door is a powerful fan that is mounted into the frame of an exterior door. The fan pulls air out of the house, lowering the air pressure inside. The higher outside air pressure then flows in through all unsealed cracks and openings. This test determines the air infiltration rate of a building.

What is infrared testing?

Thermal imaging scans can be a very helpful tool in determining the root cause of problem areas in your home. A thermal imaging camera works by seeing light in the heat spectrum, which ranges from white for warm areas to black for cold areas.

Thermal imaging shows heat losses and air leakage in a home, with the help of an infrared camera. It can reveal issues such as: air leaks around windows and doors, air leaks in building envelopes, missing insulation, and more!
