Aerosealing homes across Illinois and Northwest Indiana
In older homes from Tinley Park to Valparaiso, leaky ducts are a hidden but common culprit behind comfort issues and high energy bills. Over time, joints loosen, gaps form, and conditioned air escapes into crawl spaces, attics, and wall cavities instead of reaching your living spaces.
At Assured Insulation Solutions, we’ve used Aeroseal technology to help homeowners across Frankfort, Joliet, Crown Point, and surrounding areas eliminate duct leakage without invasive construction. Whether you live in a mid-century ranch, a 1990s two-story, or a newer build with uneven airflow, our certified team pinpoints leakage and seals it fast, with real before-and-after results.

How aerosealing improves HVAC performance
When your ducts leak, your HVAC system becomes a machine fighting against itself. Heated or cooled air escapes into unconditioned spaces before it ever reaches the rooms where it’s needed. As a result, your system runs longer, burns more energy, and still fails to deliver consistent comfort.
Aerosealing restores balance. By sealing those hidden leaks from the inside, the system can finally pressurize and deliver air evenly throughout your home. That means fewer hot spots upstairs, fewer cold spots in the basement, and a noticeable improvement in overall air circulation.
The difference isn’t just comfort, it’s measurable performance. Systems sealed with Aeroseal typically require less runtime, experience less mechanical stress, and operate more quietly and efficiently. Over time, that translates to lower energy bills, longer equipment life, and a home that simply feels better.
Risks and home impacts of leaky ducts
Leaky ducts do more than waste energy—they silently erode your home’s comfort, performance, and air quality over time.
Dust, allergens, and dirty air
Gaps in your duct system allow attic debris, insulation particles, and crawl space contaminants to enter your airflow. That air circulates through your vents, reducing indoor air quality and aggravating allergies or respiratory issues.
Rooms that never feel right
When air escapes before it reaches its destination, rooms stay hot in summer, cold in winter, and always uncomfortable. You adjust the thermostat, but the airflow simply can’t keep up.
Higher utility bills with no payoff
Leaky ducts make your HVAC system run longer and harder to compensate. The result: elevated energy bills and a home that still doesn’t feel evenly conditioned.
Overworked HVAC systems
The constant pressure loss stresses motors, compressors, and fans. That wear leads to more breakdowns, more maintenance, and a shorter system lifespan.
Undervalued performance at resale
Buyers notice poor airflow and inconsistent comfort. A home with unsealed ductwork signals inefficiency, something Aerosealing permanently corrects with documented before-and-after results.
If your heating system is barely hanging on, replacing itIf you’ve been living with airflow issues, sealing your ductwork with Aeroseal is a smart way to restore balance, protect your equipment, and elevate daily comfort without major renovations. now avoids the chaos of winter failures and sets your home up for consistent comfort and peace of mind.
Why professional aerosealing matters
Sealing ducts might sound simple, but getting it right, without tearing open ceilings or walls requires the right technology and expertise. That’s where Aeroseal stands apart.
Precise diagnostics drive the solution
Before we seal anything, we run a pre-test that pressurizes your ducts and pinpoints the total leakage. This test doesn’t rely on guesswork—it delivers hard numbers on how much air is escaping and where.
Sealed from the inside, without demolition
Unlike manual sealing, which requires cutting into walls or crawl spaces, Aeroseal works from within. We inject a safe, water-based polymer mist into your ducts. It travels with the air, finds leaks up to ⅝”, and seals them permanently—without coating the entire duct.
Results you can see and measure
Once sealing is complete, we run a post-test and give you a certificate showing the before-and-after leakage rates. Most homeowners see a 90% reduction in duct leakage immediately.
Long-lasting performance
Aeroseal seals are designed to last for decades. They remain flexible, resist cracking, and maintain adhesion even under pressure or temperature swings—far outperforming tape or mastic over time.
Backed by science, trusted in thousands of homes
This method isn’t new or experimental. It’s used in hospitals, government buildings, and ENERGY STAR homes across the country—and now it’s available for yours.
Don’t wait, schedule your duct evaluation today
