Services Backed By Science

The truth is that most builders, architects, code enforcement officials, home inspectors, carpenters, and insulation installers are not building scientists.
We use real-time diagnostics and building science data to pinpoint inefficiencies and comfort issues. Our work doesn’t stop at installation—we post-test every project to verify performance and ensure every improvement functions as designed and intended.
EnergyStar® Qualified: Meets strict efficiency guidelines for federal incentives
Data Driven

For Homeowners Who Expect More

For homeowners who value precision, long-term comfort, and results you can trust—this is where it starts. Our process begins before we even arrive, using intake details and energy history to inform a focused, data-driven site evaluation. Every step is intentional—from diagnostic testing to post-assessment modeling—ensuring that each recommendation is based on real performance data. The final report isn’t just a list—it’s a roadmap. Simple to understand, strategic by design, and customized for your home. It reflects the level of care and clarity we believe every homeowner deserves when making smart, lasting improvements.

Sealing for system performance

Leaky ducts will significantly reduce system performance, leading to increased energy bills.
Northampton and Lehigh County residents choose Aeroseal To Seal Leaky Ducts to treat DECREASED SYSTEM PERFORMANCE And poor system performance leading to higher energy bills.
The Highest Priority

Sealing For System Performance

Sealing your ducts allows the maximum amount of air to be delivered to the rooms throughout your home as it should. This allows the home to reach your desired temperature much faster, making it much more efficient with enhanced comfort immediately. Say goodbye to “dead zones” and welcome evened out temperatures in EVERY room with balanced air flow and humidity.

Even high-efficiency equipment can’t overcome a leaky distribution system
Leaky Ducts = Lost Comfort + Wasted Energy

Even high-efficiency equipment can’t overcome a leaky distribution system

When your 3 ton air conditioner is only delivering 2 tons of cooling

Up to 30% of your heating and cooling can leak out through unsealed ductwork—before it ever reaches the rooms that need it. That’s wasted money, uneven temps, and extra strain on your HVAC system.
