What a home energy audit covers in Worcester
A home energy auditor visits your home and finds where it wastes energy. Most test how much air leaks out with a blower door, check insulation in the attic, walls and basement, and look at your heating, cooling and hot water. You get a report that lists upgrades in order of value.
If your program needs an audit, book it first. Some utility insulation and air sealing programs pay only after an assessment, and some need it before any work starts. Ask your utility whether an outside auditor's report counts, or whether you must book through the program.

Before you hire a home energy auditor
- Ask whether they are BPI certified or a RESNET HERS rater, and whether they run a blower door test.
- Ask whether your utility's insulation or heat pump program accepts their report, or whether you must book through the program.
- Ask what the audit costs, what the report includes, and whether a test-out visit after the work costs extra.
- Ask whether they also sell or install upgrades. An auditor who does not sell gives the most neutral advice.
