Chances are, you’re spending much more on utility bills than you need to be. Using the latest technology — including a blower door to assess air leakage, infrared thermography, and combustion safety tests — our comprehensive Home Energy Audit will point out leaks in your home’s thermal envelope, insulation gaps, and other opportunities to stop heat loss and reduce energy consumption while improving the comfort and safety of your home.

In addition to recommending fixes to reduce energy, we’ll also evaluate carbon monoxide safety, moisture issues that could lead to mold and other air quality issues and improvements to temperature and lighting comfort. Our thorough Audit Report will include a prioritized list of potential improvements, and an estimate of the savings our recommended work will likely generate.
