Whole-Home Diagnostics + Upgrades

A better performing home starts with the right data.

Testing, Aeroseal duct sealing, professional duct cleaning, air sealing and attic insulation—guided by measured performance and clear priorities.

Choose Your Starting Point

What would you like to improve?

Start with the concern that best matches your home: diagnostic testing, airflow and duct services, or targeted air sealing and insulation.

CERTIFIED DIAGNOSTICS • CLEAR PRIORITIES • VERIFIED RESULTS

Measure First. Improve What Matters.

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.

Aeroseal duct sealing with measured results.

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.

Watch leakage fall on the computer screen while Aeroseal seals inaccessible duct joints from the inside. The completed process produces a certified report with the measured starting point, final result and improvement.

Beyond the Test

Target the pressure boundary. Complete the thermal boundary.

Testing tells us where the home is losing control. Our in-house team then completes the air sealing, attic preparation and insulation work needed to correct the measured defects—without subcontractor handoffs.

01

Targeted Air Sealing

Seal attic penetrations, open framing paths, top plates, bypasses and access points at the home’s pressure boundary.

02

Attic Insulation

After ventilation and air sealing are complete, install uniform premium blown insulation to the prescribed R-value.

03

Ice-Dam Diagnostics

Trace heat and air pathways at knee walls, roof transitions and open floor cavities before prescribing corrective work.

Measured in the Field

Results are verified—not assumed.

Every meaningful improvement begins with a baseline and ends with measured verification. These recent anonymous project results show what that process can deliver.
