Internal Duct Sealing Technology

Aeroseal Duct Sealing

Seal hidden duct leaks from the inside to improve comfort, airflow, efficiency, and indoor air quality without tearing open your walls or ceilings.

Why Aeroseal Matters

Hidden duct leaks can waste comfort, airflow, and energy

Duct leakage is often out of sight, but it can have a major impact on home comfort and HVAC performance. Aeroseal is designed to address that problem from inside the duct system, helping more conditioned air reach the spaces where you actually live.

Efficiency losses add up fast

Even high-efficiency heating and cooling equipment can underperform when leaky ductwork wastes airflow before it reaches the rooms of your home.

Key Benefits

Better comfort, stronger airflow, and less wasted energy

Aeroseal is often a smart solution for homes dealing with hot and cold rooms, weak airflow, dust issues, and duct losses that make the HVAC system work harder than it should.

Improve Home Comfort

Aeroseal helps conditioned air reach the rooms where it belongs, improving temperature balance and reducing hot and cold spots throughout the home.

Boost System Performance

When duct leakage is reduced, your HVAC system can move air more effectively and operate closer to the performance you paid for.

Cleaner Indoor Air

Sealing leaks in return ductwork can help reduce the amount of dust, allergens, and pollutants pulled in from attics, walls, crawlspaces, and other unconditioned areas.

Lower Energy Waste

Leaky ducts can force your equipment to run longer than necessary. Sealing those leaks can support lower wasted energy and more efficient operation.

Less Intrusive Process

Aeroseal is designed to seal leaks from inside the duct system, making it a strong option when traditional manual duct sealing would be difficult or invasive.

Measured Results

Aeroseal systems are known for before-and-after leakage testing, giving homeowners a clearer picture of improvement after the process is complete.

Before & After

These visuals help explain how hidden leaks can impact home performance and why internal duct sealing can be such a valuable upgrade.

Before Aeroseal

Leaky ductwork can allow conditioned air to escape and unfiltered air to enter the system, hurting comfort and efficiency.

After Aeroseal

Once leaks are sealed internally, more conditioned air can stay inside the duct system and reach the intended living spaces.

How It Works

A step-by-step look at the Aeroseal process

The process is designed to be efficient, measurable, and far less invasive than opening up large sections of finished walls or ceilings to chase hidden duct leaks.

Inspect & Test

We evaluate the duct system, identify leakage concerns, and prepare the system for sealing.

Prepare the System

Registers and vents are prepped, the system is isolated, and specialized Aeroseal equipment is connected to the ductwork.

Seal From the Inside

A safe sealing mist is introduced into the duct system, where particles gather at leak edges and build a seal internally.

Verify Improvement

After sealing, the system is re-tested so you can see measurable leakage reduction and stronger overall performance.
