In-home energy-saving audits

Whole-house approach to energy efficiency

If you wish to solve comfort problems or reduce your energy bills, Minnesota Energy Resources can help. When you sign up for an in-home energy-saving audit an energy auditor will make an in-home visit and provide energy-efficiency suggestions to improve the comfort, durability, safety and affordability of your home. The energy auditor will:

  • Analyze your home through a comprehensive "House as a System" energy-efficiency audit
  • Answer your specific questions about energy use in your home
  • Review your natural gas bill to understand how much energy your home uses. In some instances, as a result of electric utility partnerships, electric energy use is also evaluated
  • Provide recommendations and cost saving analysis, prioritized to show you where you'll get the most savings for your investment

Levels of audits:

  1. Standard audit

    The standard audit will:
    • Analyze your energy use
    • Give you information on energy-saving measures with potential costs and estimated savings
    • Provide a blower door diagnostic test
    • Perform a furnace efficiency and combustion safety test
    • Provide a natural draft and worst-case depressurization test if the home has atmospherically-vented appliances
    This service is valued at $300; however, you only pay $50. Minnesota Energy Resources and, in some cases, the electric utility partner, pay the remainder. This co-pay will be added to your natural gas bill. Low income customers may participate in this program at no cost.
  2. Performance audit

    In addition to all of the services provided in the standard audit, the performance audit will also include:
    • An infrared camera inspection to further pinpoint the location of heat loss and air leaks, and
    • A report with infrared camera pictures will be emailed to you
    A co-pay of $125 will be added to your natural gas bill.

Which audit is best for you?

For some homes, our standard audit is sufficient. For others, there can be significant benefit in having a performance audit completed. If you have already had a standard audit and are still having energy efficiency or comfort issues in your home, a performance audit could be what you need. Or, if you notice two or more of the following in or around your home, our performance audit may be for you.

  • Ice dams on the roof
  • Moisture or frost in the attic
  • Mold or moisture spots on interior walls
  • Condensation on your windows
  • Stains around ceiling exhaust fan(s)
  • Cold spots in areas of the house
  • Inadequate or older insulation
