Aeroseal duct sealing seals air duct leaks from the inside using a safe, water-based sealant. The procedure blasts tiny sealant particles inside the ductwork, which stick to leaks and holes without covering the entire duct. This approach maintains indoor air quality, conserves energy, and prolongs HVAC longevity. A lot of houses and buildings seal with aeroseal duct sealing to resolve comfort problems and reduce energy bills. Industry experts prefer this option because it seals both existing and new ducts and doesn’t require major changes to walls or ceilings. The following will demonstrate how aeroseal duct sealing works and what kind of results people can anticipate.
The Technology
Aeroseal duct sealing is based on a clever way to repair air leaks in ducts from the inside. It centers on increasing energy efficiency, reducing air leakage and maintaining indoor air quality. This technique employs a sealant spray, compressed air and live mapping to seal up the cracks and drafts that commonly plague houses and structures.
1. The Principle
Aeroseal leverages tiny polymer sealant particles, blown into the ductwork with pressurized air, that adhere to and seal holes as narrow as hairline cracks and as large as 16mm. These particles are propelled through the ducts by pressurized air, locating and sealing even difficult-to-access leaks.
Sealing these mini-cracks is crucial because leaks allow 25–40% of heated or cooled air to escape, essentially making heating and cooling less efficient. By sealing these gaps, the innovation not only helps keep home temperatures more consistent and saves energy, but can reduce utility costs by up to 30%. It reduces the risk of dust and other particles infiltrating the system, aiding your indoor air quality.
2. The Process
The aeroseal process begins with a comprehensive evaluation—inspectors test for leaks and quantify air loss. Then, all air vents are closed up other than the main duct. The system is then hooked up to the aeroseal machine, which injects a harmless, adhesive mist into the ducts. This mist locates and patches leaks as it moves. Sensors and computers monitor the process in real time, displaying leak reduction as it unfolds.
Unlike conventional sealing, aeroseal doesn’t cut through walls or ceilings, it’s performed from within the ductwork. Most homes complete the process in 4–8 hours, depending on the size and number of leaks, meaning it’s a speedy, non-invasive solution.
3. The Sealant
The sealant contains water-based polymers, with recognizable ingredients such as glycerin and propylene glycol. Because these materials go in soap and food, the sealant is non-toxic and safe to use indoors. It’s engineered to last 40+ years and backed by a 10-year warranty, providing a long-term seal for air leaks.
This sealant resists temperature and moisture, so it’s effective in a variety of climates. Preferred care will detect a slight smell upon application, but it dissipates quickly once applied.
4. The Verification
Check is a crucial phase. After sealing, experts utilize duct cameras and pressure tests to verify that leaks are sealed and air flow is optimized.
These checks assist in ensuring that the sealing is efficient and that the system is operating optimally. Routine post-installation inspections maintain indoor air quality and energy savings.
Method Comparison
Duct sealing techniques differ significantly in their mechanisms, durability, and expense. Aeroseal is different because it utilizes a liquid sealant that moves through the ducts in order to locate and seal leaks internally. This renders it invaluable for leaks in places hands or tools can’t access–particularly large buildings or homes with ducts behind walls or above ceilings. In contrast, mastic sealant and foil tape are ideal for leaks you can see and feel. Mastic is effective for cracks less than 6mm and foil tape is convenient on seams and joints. Duct insulation is another option, primarily for ducts in attics or basements, and is a frequent DIY activity.
| Method | Best Use Case | Lifespan | Skill Needed | Cost (USD) | Reach |
|---|---|---|---|---|---|
| Aeroseal | Hard-to-reach leaks, large systems | 10–20 years | Pro only | $1,200–$3,200 | Full system |
| Mastic Sealant | Small cracks, visible leaks | 10–15 years | DIY/Pro | $10–$50 | Limited |
| Foil Tape | Joints, seams | 5–10 years | DIY/Pro | $10–$30 | Limited |
| Duct Armor | Small holes, restoration | 10–15 years | Pro only | $2,000–$3,200 | Full system |
| Duct Insulation | Unconditioned spaces | 10–20 years | DIY/Pro | $1–$3/sq. metre | Limited |
| Sealant Spray | Tight spots, small leaks | 5–10 years | DIY/Pro | $20–$100 | Limited |
Efficacy is a function of the kind of leak and location. Aeroseal seals up to 90% of leaks – even the ones you can’t reach by hand. Mastic and foil tape fares well for exposed surfaces but cannot penetrate within walls. Duct armor remains a pro method of sealing smaller holes when restoring. Duct insulation is less about air sealing and more about retaining heat or cold.
Aeroseal is more expensive, but it returns with reduced energy bills. Sealed ducts can reduce energy waste by as much as 30 percent and increase efficiency by as much as 90 percent, which counts in a big home or building. DIY methods such as mastic or foil tape are less expensive, but are more time consuming and can overlook hidden leaks. Most methods persist for decades, but their longevity depends on how effectively they are implemented and maintained.
Tangible Benefits
Aeroseal duct sealing has immediate, tangible benefits for homes and businesses alike. Duct sealing means obvious savings on your energy bill, healthier indoor air, and more consistent heating and cooling throughout your home. All of these benefits add up to tangible wins in comfort, health and long-term savings.
Energy Savings
| Duct Leakage Reduction | Average Energy Savings (%) | Example: Monthly Bill Before | Example: Monthly Bill After |
|---|---|---|---|
| 10% | 6% | $150 | $141 |
| 20% | 12% | $150 | $132 |
| 30% | 20% | $150 | $120 |
| 36% | 23% | $150 | $116 |
One of the biggest easy-to-get-at culprits is duct leakage, which can waste 30% of heating and cooling energy. When you seal these leaks, your system doesn’t have to work as hard to maintain temperatures. This translates into less power consumed and smaller monthly bills. For instance, homeowners commonly observe a reduction in utility expenses shortly after sealing. We’ve typically observed savings of 10% to 23% on monthly bills, depending on leakage repairs.
The return on investment is obvious. Sealing ducts is a one-time investment that continues to return dividends for years. Rather than money leaking out through secret cracks, families and businesses retain more of what they invest in comfort.
Air Quality
Aeroseal duct sealing helps keep indoor air clean, by blocking out the dust, pollen and other pollutants that leak through. With ducts sealed, fewer allergens and dust intrude into rooms and people breathe easier, particularly those with allergies or asthma.
Clean ducts assist ventilation systems to function more efficiently. Fresh air can push in and stale air gets pushed out. This effect is amplified with a whole-home ventilation system, which enhances air quality even more.
A healthier home begins with less indoor pollutions. Folks notice less sneezing, coughing and irritation when leaks get repaired.
Comfort Levels
- Fewer drafts in living rooms, bedrooms, and hallways
- Even warmth in winter and coolness in summer in every room
- Equalized air to former hot/cold spots.
- Consistent comfort, even on very hot or cold days
Leaky ducts allow hot or cold air to escape, so certain rooms receive diminished comfort. Sealing fixes this. The air flows to where it’s required, no more hot upstairs or frigid nooks.
When it’s cold, sealed ducts = your system keeps up without working overtime. No more sky-high energy bills or cranking it up longer just to ‘feel’ right.
Ideal Applications
Aeroseal duct sealing is great for residences and commercial or industrial spaces, especially those with leaky ducts or high energy wastage. Leaky ductwork in older homes contributes to high energy bills and insufficient air flow. These leaks allow up to 30% of your air to escape, making your heating or cooling system work harder. Sealing these ducts both cuts energy use, keeps indoor air cleaner, and makes rooms feel more even in temperature. That’s just good stuff for anyone experiencing dust build-up, hot/cold spots or rising utility costs.
In new construction, aeroseal is fantastic on projects with complex duct systems. Sleek contemporary HVAC systems in commercial offices or multi-level homes are difficult to caulk by hand. Aeroseal can access secret leaks deep in the system, making it a clever option for new construction that wants to satisfy rigorous energy codes or go green. This aids owners and builders in hitting energy efficiency targets from the get-go, while maintaining system operation as intended.
Aeroseal duct sealing is compatible with most HVAC systems including central heating, air conditioning and heat pumps. Any of these can have leaks that damage system throughput. In central HVAC homes with lots of ductwork, plugging leaks can help the system run smoother and last longer. In heat pump systems popular in cold and hot climates, duct sealing translates into greater comfort and reduced operating costs.
This fix fares well in areas that encounter extreme weather or humidity, as leaky ducts can suck in external air, allergens, or moisture. Sealing prevents this, so the inside air remains fresher and more consistent. For those with allergies or breathing issues, this can be a huge difference.
Duct sealing is excellent for those seeking to claim tax credits or rebates for energy upgrades, as with government programs like the Inflation Reduction Act. Which makes aeroseal not just a smart, but a frugal smart fix.
Installation Realities
Aeroseal’s duct sealing is the new way to fix duct leakage. Most homes and commercial establishments have ducts that leak more than 15%. That translates into wasted energy, more expensive utility bills and reduced indoor comfort. Advance planning is essential—ducts must be clean, with less than 3 mm of dust or debris, prior to sealing. Professional technicians use professional tools to test the system, locate leaks and prepare everything for the sealant. It’s less invasive than conventional approaches and frequently enables facilities to continue operating normally.
The Misconceptions
Some believe aeroseal duct sealing is messy, costly, or untested. Some fret about pungent chemical odors or wonder if the seals hold. Actually, the sealant’s smell is faint, like kid’s glue, and dissipates in a few hours. Scheduling errands on install saves you discomfort. Cost is usually made up for by energy savings and enhanced performance. The sealant itself is demonstrated to last more than 40 years, and safety testing is rigorous. It’s not like you’re tearing out walls or ceilings or anything. Homeowners are always looking for fast answers, but we need to take time to test and apply correctly. Testing now includes lower-pressure ducts, which makes testing more reliable for a wider variety of systems.
The Challenges
- Ducts that are heavily contaminated with debris or damaged must be cleaned and repaired prior to sealing.
- Rooms with inaccessible ductwork will bog the process down.
- Aged or cheap duct materials don’t always seal well.
- Specialized equipment and expert consultants are required for optimal performance.
Technicians frequently encounter neglected or concealed duct work. Severe rust or caved-in portions may prohibit a proper seal. Using the right tools and good crews goes a long way to fixing most problems. Smart layout and the first pass through is what gets you a good result.
The Integration
Aeroseal is compatible with the majority of HVAC systems, installing on both metal and flexible ducting. It adjusts to any floor plan, from a single straight run to elaborate branches.

Durability
Aeroseal seals maintain their grip even in challenging environments. These seals resist extreme heat, cold and high humidity and won’t deteriorate quickly. In dry or humid conditions, from freezing to blazing weather, the sealant stretches and adheres as required. Its chemistry makes it outlast typical tapes or mastics. Most homeowners experience seals holding for 5-10 years or longer, depending on how clean the ducts are and the moisture level in the air. Studies demonstrate that as much as 95% of leaks can become sealed, which means the air stays where it belongs—regardless of what is occurring outside. Opt for a hard wearing seal and you’ll have less patching and fewer headaches in the long run.
Maintenance
- Check ductwork every 2–3 years for leaks or cracks.
- Clean registers, grilles, and air filters every few months.
- Replace air filters as needed to keep airflow smooth.
- Look for uneven heat or cold—this may indicate leaks.
