Ducts are used for distributing air throughout your home so that your HVAC doesn’t work too hard. Your HVAC system will be forced to work extra hard to keep your home comfortable when you have poorly connected or sealed ducts. Poorly sealed ducts allow air to get lost. In other words, duct leaks lead to spending more money on cooling and heating your home. The few extra dollars you spend might not seem like a lot of money, but it adds up quickly on your utility bills! Therefore, it’s prudent to ensure that your conditioned air doesn’t escape through some unnecessary pesky ductwork in your home by using the Aeroseal duct sealing method.


What is Aereoseal? Aeroseal is a duct sealing practice developed by the US Department of Energy & Environmental Protection Agency to help homeowners and commercial building owners avoid bad air distribution, energy inefficiency, and issues arising from air duct leakage. Unfortunately, many homeowners are unaware of the existence of leaky ducts in their homes because most ductwork is concealed in walls and other hidden locations. Property owners end up spending a lot of money on heating and cooling to make their homes comfortable. By knowing what is Aeroseal duct sealing and how it can help you, you can seal all gaps and cracks by using a non-toxic aerosol process.


Before and After Aeroseal Duct Sealing

Before and After Aeroseal Treatment


Ductwork has the supply and return sides. While the supply side pushes treated air into your rooms, the return side pulls air back into the HVAC system for reconditioning and recirculation. Hence, leaks in the return side of the duct system pulls air into air ducts from undesired places such as crawl spaces or attics. Thus, the air from the undesired sources circulates into your rooms, bringing with it pollutants such as dirt and dust.


  • Excessive Dust – Presence of excessive dust in your rooms means that you could be having duct leaks problem. The leaky ducts pull dust and other harmful pollutants into your home.
  • Musty Odor and Fume Smells – With poor ductwork, you can start experiencing auto exhaust, radon gas and gas appliance fumes in your rooms. Aeroseal duct sealing application helps eliminate these uncomfortable smells because once the air is treated it doesn’t escape.
  • High Energy Bills – If you experience increased energy bills, even without making any changes on how you spend energy in your home, chances are you have leaky ducts.
  • Noticeably Hot or Cold Rooms – Cracks and gaps in your ductwork allow conditioned air to escape into attics and crawl spaces. In other words, treated air will not be beneficial to your rooms.
  • Excessive Humidity – Gaps and cracks in your ductwork can pull humid air from outside into your rooms, making them humid and uncomfortable.



The cutting-edge technology was patented by the Department of Energy in the 1990s at UC Berkley. Since then, it has been one of the most important modern technologies to American consumers. During application, One Hour Heating & Air Conditioning technicians inject a fog of aerosolized sealant particles in your duct system. The sealant particles stick together blocking and sealing holes and gaps from inside your ducts effectively.


The Aeroseal duct sealing process doesn’t leave any lingering odors in your home. Also, it’s non-toxic because it comprised of a UL-tested sealing substance that is used in hair sprays, chewing gum, and in water-based paints. In fact, OSHA doesn’t have an exposure limit for Aeroseal vinyl acetate polymer (VAP) due to its good track record.


After application, you can be guaranteed that your home’s heating and cooling will be energy efficient for over 10 years before requiring replacement. The duct sealing application has been lengthily researched and tested in the most arduous cooling and heating environments. Moreover, investing in the Aeroseal duct sealing system is cost-effective considering that you will save a lot of money during this period.


The more ineffective your ductwork, the harder your HVAC system will have to work to regulate air circulation in your rooms. Studies show that typical American homeowners spend up to $2000 per year on energy bills, and around 30 cents of every $1 spent is often lost due to poorly maintained ductwork. In a recent research commissioned by the American Council for Energy Efficient Economy, ductwork sealing was ranked among the top 15 energy saving technologies. Aeroseal duct sealing technology can help you save hundreds of dollars every year. Moreover, when you spend less energy, you reduce your carbon footprint, which also benefits the environment.


Indoor air pollution is considered a major health concern. When your ductwork has a problem, external contaminants, dust and other chemical pollutants can find their way into your ventilation system through gaps and cracks, and they end up recirculating in your home. Aeroseal duct sealing and frequent duct cleaning will reduce chances of occupants suffering from asthma, allergies and respiratory symptoms.
Enhanced air quality

Poor ductwork can lead to accumulation of dirty and humid air in your rooms coming through from your attic or crawl space. In addition, this air can promote mold growth that can also lead to mold damage, which can be costly to mitigate. Aeroseal duct sealing not only helps you and your family stay healthy, but also reduces overall home maintenance costs.


Have you been facing inconsistent room temperatures throughout your house? If you realize that some of your rooms are sweltering while others are fairly cool, then you need Aeroseal duct sealing services. The application will immeasurably help reduce the room temperature differences in your entire house, and consequently improve the consistency of your HVAC system.
