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.

Test My Home

Blower door, duct-leakage and diagnostic testing to identify what is actually happening.

Improve My Airflow

Aeroseal and professional duct cleaning for better delivery, comfort and indoor air quality.

Fix Drafts & Insulation

Targeted air sealing, attic insulation and ice-dam solutions based on measured defects.

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.

Finally get the air you paid for.

At Lehigh Valley Aeroseal, located in Bethlehem, PA, we specialize in transforming spaces into energy-efficient environments. Our expert team conducts thorough energy efficiency assessments to identify and seal leaks, ensuring your home or business operates at peak performance. Committed to innovation and sustainability, we help reduce energy costs while enhancing comfort and air quality.

Partner with us for a cleaner, greener future.

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.
