When Is the Cheapest Time to Schedule Energy Audit?
Timing your energy audit project strategically can save thousands. Here is how pricing varies by season:
Spring (Mar-May)
Perfect weather for envelope inspections; mild temps reveal draft and leak issues
Summer (Jun-Aug)
Blower door tests can identify AC duct leakage; peak AC load tests revealing
Fall (Sep-Nov)
Good season for comprehensive audit; moderate temps make window/door assessment ideal
Winter (Dec-Feb)
Heating season audits show greatest energy savings potential

What Affects Energy Audit Cost?
Size & Scope
Larger energy audit projects naturally cost more. Square footage and project complexity are the biggest cost drivers.
Project Tiers
Budget, standard, and premium tiers can vary in cost by 2-3x. See the tier breakdown above.
Season & Timing
Off-season scheduling can trim costs (our calculator applies up to a 15% winter adjustment on weather-sensitive work). Emergency work commands a premium.
Existing Condition
Structural damage, mold, or outdated systems can add unexpected costs during the project.
Permits & Inspections
Energy audits do not require permits. BPI or RESNET certification recommended for auditors. Blower door testing has no regulatory restrictions. Recommendations may require permits when implemented.
