Why Should I Have A Home Energy Audit?

Performing a home energy audit is the first step toward cutting utility costs and making your home more comfortable....


Audits, or energy assessments, are examinations of a home's exterior construction or envelope and the systems within the home.  Audits measure the amount of energy a property uses and identifies why and where energy is being lost.  Frequent causes of energy loss are leaky windows, a poorly sealed atticductwork tears, and invisible cracks.


Professional auditors rely on various tools, the most common being blower door tests and thermographic inspections.

The tests, requiring three to four hours, help auditors discover where there is air infiltration or loss and pinpoint hidden, hard-to-reach spots where insulation is lacking or failing.

An auditor uses the test results, along with other data about your hearing and cooling habits and utility costs, to identify the home improvement projects that will boost a home's efficiency.


By making upgrades following a home energy assessment, homeowners can save between 5% and 30% on energy bills, according to the U.S. Department of Energy.

And repairs are not always big, high-ticket items.  For example, some upgrades, such as air sealing and insulation, can be completed using a DIY approach.  For examples, visit
