Duct Sealing

Advanced Aeroseal technology that seals your ducts from the inside out

What is Aeroseal Duct Sealing?

Aeroseal is a patented, breakthrough technology developed at Lawrence Berkeley National Laboratory that seals duct leaks from the inside out. The U.S. Department of Energy rated Aeroseal as one of the 23 most beneficial technologies available to American consumers.

The average home loses 30 cents of every energy dollar through leaky ductwork. Aeroseal can seal up to 95% of duct leaks, dramatically improving your HVAC system's efficiency and your home's comfort.

Benefits of Duct Sealing

Experience the difference that properly sealed ductwork can make in your home

Energy Savings

Reduce energy expenses by up to 40% each month. Stop losing conditioned air through leaky ducts.

Better Comfort

Eliminate hot and cold spots throughout your home. Every room receives proper heating and cooling.

Improved Air Quality

Seal entry points that allow dust, allergens, and contaminants into your duct system and home.

Extended HVAC Life

Reduce wear and tear on your heating and cooling equipment when it doesn't have to work as hard.

Safe & Non-Toxic

The sealant is water-based, non-toxic, non-flammable, and mold resistant. Safe for your family.

Long-Lasting Results

Aeroseal can last up to 40 years and comes with a 10-year warranty for residential applications.

How Aeroseal Works

A simple 4-step process that typically takes just 4-8 hours

Step 1: Prep the ductwork - technician sealing registers

Prep the Ductwork

All registers are blocked to pressurize the ductwork. Vital components like furnaces and coils are protected to prevent contact with the sealant.

Step 2: Connect Aeroseal equipment to ductwork

Connect Equipment

The Aeroseal equipment is connected to your duct system. A pretest measures initial leakage to verify the seal's effectiveness afterward.

Step 3: Seal the ductwork from the inside

Seal the Ductwork

Non-toxic sealant is atomized into your ducts. The particles collect in cracks and gaps, sealing leaks from the inside. Real-time monitoring tracks progress.

Step 4: Certified results showing before and after leakage

Certify the Results

A detailed seal report is generated comparing before-and-after leakage rates. Your HVAC system is restored and ready to use within 30 minutes.

Why Choose Aeroseal Over Traditional Methods?

Traditional duct sealing relies on hand-applied mastic and metal tape, which can only reach accessible areas. If a technician can't physically access the ductwork, it can't be sealed. Additionally, tape adhesive breaks down over time due to temperature extremes.

Aeroseal works from the inside, reaching leaks in walls, ceilings, and other inaccessible areas without tearing apart your home. The computer-controlled process ensures complete, verified sealing with documented results.
