Home Energy Efficiency Audit Checklist — Locust, North Carolina

Measure depth and calculate R-value. Most homes need R-38 to R-60 in the attic depending on climate zone.

Hold a lit incense stick near windows, doors, outlets, and plumbing penetrations. Smoke movement reveals leaks.

Check visible ducts in attic and basement for gaps, disconnections, or damaged insulation. Leaky ducts waste 20-30% of conditioned air before it reaches your rooms.

Check for drafts, condensation between panes, and single-pane windows. Consider films or replacement.

Compare year-over-year usage. Increasing consumption with similar weather indicates declining efficiency.

Older units run 50-60% efficiency. Modern units hit 95%+. Calculate payback period.

A BPI-certified auditor uses blower door tests and thermal imaging to find invisible energy waste.
