Blower door testing, duct-leakage measurement, pressure diagnostics and infrared imaging reveal where comfort and energy are being lost—so every recommendation is based on measured evidence.
At Lehigh Valley Home Performance, powered by Project Probono LLC, we pair Aeroseal duct sealing with diagnostic testing to locate duct leaks, improve airflow and verify results. Our in-house team serves Bethlehem, Allentown, Easton and surrounding Lehigh Valley communities, bringing building science experience since 1997.
From the initial leakage test through final verification, every step supports better comfort, efficient air delivery and clear, documented results.
