Aeroseal Duct Seal: How It Improves Air Quality and Efficiency

Understanding Aeroseal: How It Works to Improve Air Quality

Concerns about indoor air quality and rising energy bills have become more common among homeowners. Hidden duct leaks are often the cause of discomfort, dust buildup, and inefficient HVAC performance. Aeroseal is a breakthrough duct sealing technology designed to fix these problems from the inside out.

This blog explains how Aeroseal works, the benefits it offers for air quality and energy savings, how it compares to traditional duct sealing, and what homeowners can expect during the process.

What Is Aeroseal and How Does It Work?

Aeroseal is a patented duct sealing process that targets leaks within your ductwork to boost HVAC efficiency and improve air quality. Unlike surface-level solutions, Aeroseal works from the inside of the system using a four-step approach.

Pressurization

The technician begins by sealing off vents and pressurizing the duct system. This test identifies where air is escaping and how severe the leaks are.

Particle Injection

Once the system is closed and pressurized, small, non-toxic sealant particles are injected into the ducts. These particles remain suspended in the airflow.

Seal Formation

As air tries to escape through gaps and cracks, the particles stick to the edges of each leak. Over time, they build a strong, flexible seal that closes the opening.

Verification

After the sealing is complete, the technician runs another test to confirm the reduction in air leakage, often by more than 90 percent.

This method is especially effective for sealing gaps that are hidden behind walls, in ceilings, or in tight crawl spaces that are unreachable with traditional tools.

The Benefits of Aeroseal for Air Quality and Efficiency

Improved Air Quality

By sealing leaks in your ductwork, Aeroseal prevents dust, allergens, and contaminants from entering your HVAC system through wall cavities or attics. It also helps limit moisture intrusion, which can reduce the risk of mold growth.

Energy Savings

Leaky ducts can allow up to 30 percent of conditioned air to escape before it ever reaches your living space. Aeroseal helps stop that energy loss, reducing the workload on your system and lowering utility bills.

Enhanced Comfort

By ensuring balanced airflow, Aeroseal can eliminate hot and cold spots in your home. It also promotes quieter system operation by reducing air turbulence.

Eco-Friendly Results

Using less energy means a smaller carbon footprint. Aeroseal supports energy-efficient HVAC practices while improving everyday comfort.

Aeroseal Technology: How It Stands Out

Traditional duct sealing methods often involve applying foil tape or mastic paste to the exterior of duct joints and seams. While effective on exposed ductwork, these solutions have limits.

Traditional Methods

• Only seal areas that are easy to reach
• Can degrade over time from heat, age, or air pressure changes

Aeroseal

• Seals leaks from inside the duct system, including gaps in walls or ceilings
• Forms durable, flexible seals that last over 10 years
• Uses a non-toxic, FDA-approved sealant that is safe for household environments

The precision and longevity of Aeroseal make it a standout choice for homeowners seeking reliable duct sealing.

Is Aeroseal Right for Your HVAC System?

Aeroseal is compatible with most ducted HVAC systems, including those used with central air conditioning, furnaces, and heat pumps. It is especially useful for homes experiencing:

• High utility bills caused by inefficient ductwork
• Uneven temperatures or airflow throughout different rooms
• Excess dust or worsened allergy symptoms

Homes that are newly constructed and certified as tightly sealed may not need Aeroseal, although this level of construction is rare.

What to Expect During the Aeroseal Process

A typical Aeroseal service begins with a thorough inspection. The technician uses diagnostic equipment to measure airflow and identify duct leakage levels.

Next, the home’s registers and vents are temporarily sealed. The system is then pressurized, and the sealant particles are introduced into the ductwork. Most jobs are completed in one to three hours, depending on the size and condition of the system.

There is no cleanup required. The sealant dries instantly and remains inside the duct system. Homeowners typically notice improved airflow and better system performance right away.

Aeroseal Safety and Longevity

Aeroseal is not only effective but also safe for families, pets, and sensitive environments. The sealant is:

• Non-toxic and odor-free
• Proven safe by third-party testing and FDA approval
• Designed to last for over a decade with no additional maintenance

The material remains flexible and resistant to cracking, even as your HVAC system expands and contracts through seasonal use.

Understanding Aeroseal Conclusion

If you are concerned about indoor air quality, high energy bills, or rooms that never seem comfortable, Aeroseal may be the solution. It targets hidden duct leaks, reduces energy waste, and helps your HVAC system perform the way it should.
