Types of Home Energy Diagnostics

We offer two levels of energy diagnostics:

1. Standard Diagnostic
  • The Standard Diagnostic 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.
2. Expanded Diagnostic

In addition to all of the services available in the Standard Diagnostic, the Expanded Diagnostic will also include:

  • An infiared camera inspection to further pinpoint the location of heat loss and air leaks
  • A report with infrared camera pictures emailed to you.

Do you need an energy diagnostic?

For some homes, our Standard Diagnostic is sufficient. For others, there can be significant benefit in having a Performance Diagnostic. If you have already had a Standard Diagnostic and are still having energy issues in your home, a Performance Diagnostic could be what you need. Or, if you notice two or more of the following in or around your home, our Energy Diagnostic 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.

We are in the Energy Diagnostic business to reduce your energy usage. You will be credited for any diagnostic fees if we are selected as the contractor to perform the recommended retrofits. Additionally, there are no diagnostic fees if the diagnostic is performed to confirm or “test out” the retrofit work.
