Most homes should have their air ducts inspected every 3–5 years, and sealed if leakage exceeds typical thresholds. Newer or recently sealed systems may go 5–7 years between inspections. Homes that have had remodels, additions, or HVAC replacements should be re-inspected because changes upstream often create new leaks.
Recommended schedule
- Inspect every 3–5 years for most homes
- Re-inspect after any remodel, addition, or new HVAC
- Seal whenever measured leakage exceeds energy-code thresholds
- Re-seal isn’t typically needed after a quality Aeroseal job
We provide measured leakage testing during every air duct inspection and recommend sealing only when it will deliver real ROI. See duct sealing and Aeroseal options.
