AEROSEAL DUCT SEALING

Leaking air ducts can greatly diminish your HVAC system's ability to heat and cool your home. When you turn your air conditioner or furnace on, it draws ambient air into the system from your home, heats or cools the air and pushes it through your air ducts.

When ambient outside air enters into your ducts through gaps and holes, it warms your cooled air in the summer and cools your heated air in the winter, which means your furnace or air conditioner has to work harder to reach your thermostat setting, which can cause your system to wear out faster and increase your energy bills.

In addition to making your HVAC unit less efficient, allowing outside ambient air into your home or business can increase your indoor pollution by allowing allergens and dirt into your ducts where it is then blown throughout your home or commercial building.

How aeorseal duct sealing works

Although large holes and breaks in your duct work are relatively easy to find and seal using metal or mesh tape, the dozens of smaller holes that can occur due to corrosion, gaps between duct work joints or registers are much harder to locate and seal. These small holes can add up to a large amount of escaping air. The average home has between 30-40% typical duct leakage. AIRDUCT CLEAN uses a patented breakthrough technology, Aeroseal, to seal all gaps and holes in your duct work.

The AIRDUCT CLEAN Aeroseal process:

  • Pressure test your duct work system
    • Plug all registers in your duct work
    • Apply air pressure to the system
    • Watch for any drop in air pressure. This is indicative of holes and breaks in your duct work system
  • Inject the Aeroseal non-toxic, UL tested and approved, aerosol sealant into your duct work
    • The injection process of the Aeroseal aerosol sealant is computer controlled and monitored so that you can see the effective results of the sealing process in in real time.
    • The aerosol particles begin to collect around the edges of any holes or breaks in your duct work, sealing any holes in your duct work system up to 5/8ths of an inch and only leavs 1-2 oz of residual product outside of the holes being sealed..
  • Review your results
    • You are provided a printout of a computer generated analysis that summarizes the reduction in duct leakage.

Why Aeroseal?

  • Made from a water-based non-toxic green friendly sealant, the same material used in bubblegum and pacifiers
  • Fills Holes in your duct work up to 5/8th of an inch or roughly the size of a quarter*
  • The EPA recommends Aeroseal as one of the top three things to save energy in your home
  • Average jobs take just six to eight hours from start to finish
  • 10-year warranty on product and labor
  • Reduces air duct leaks 80 to 99%
  • Improve overall heating and cooling capacity by 20 and 40%.
  • The national average for return on investment for Aeroseal is 2 to 5 years

Why you need aeroseal duct sealing

All homeowners and businesses can benefit from aeroseal duct sealing, even if the HVAC unit and air ducts are only a few years old. This is especially true if you have noticed a steady increase in your heating and cooling bills, uneven building temperatures, stuffy rooms and an increase in indoor allergy symptoms.

Your energy bills increase because you are losing part of your heated or cooled air through the gaps and holes in your ducts and allowing outside air into your ducts, which increases the overall temperature of your climate controlled air. This results in your unit operating longer and working harder to cool the same amount of square footage.  When your furnace or air conditioner operates for extended periods of time, it incurs more wear and tear than normal. This can result in the need for more frequent repairs and lead to costly breakdowns of your system.

If you have allergies, leaky air ducts could increase your symptoms. Pollen, dust, dirt and ground level ozone can enter your home or business through the gaps in your ducts, which decreases your indoor air quality, leading to an increase in sinus congestion and allergy symptoms. The particulate matter also floats through your air where it is eventually sucked into your air conditioner or furnace, where it could create filter clogs and reduce the flow of air through your system.

*  Aeroseal will not seal holes in concrete. Aeroseal only seals holes in your duck work, nowhere else.

Frequently Asked Questions

What size of holes can be sealed using the Aeroseal duct sealing process?

Holes and cracks up to 5/8th of an inch wide can be completely sealed. Once the Aeroseal process is complete, the contractor will assess any holes that may be larger than 5/8th of an inch and review manual sealing options with you.

What are the estimated savings?

A series of government reports have shown that aeroseal duct sealing can lead to up to $850 in energy savings per year. Some homeowners have saved up to 40% on their energy bill. Naturally, exact savings are difficult to precisely estimate since they depend on a multitude of variables such as your weather, house condition and design, your heating and air conditioning system, system usage – as well as other factors like energy prices.

Also, all Aeroseal air duct certified technicians are qualified to run a program made by the Environmental Protection Agency (EPA) called “Duct Investor”. Duct Investor takes a comprehensive list of variables and provides a homeowner with the best available estimate of what they should realize in cost savings.

Does the aeroseal duct sealing material become brittle?

The vinyl sealing material remains rubber and pliant. It does not crack with time or exposure to heat/cold.

How long will the aeroseal duct sealing material last?

The sealing material has been found in rigorous testing to last over 10 years without failure.

Do air ducts need to be cleaned before aeroseal duct sealing?

It’s likely that the holes and cracks in the ductwork have allowed dust and other particulate matter to enter the system. If you are experiencing extensive levels of household dust, this might be the reason. In most instances, duct cleaning is not found to be required prior to Aeroseal sealing. Your Aeroseal contractor can advise whether it will be necessary to clean your ductwork prior to sealing.

Does the sealant coat the inside of the ductwork?

The sealant only sticks to the holes in the air duct without coating the rest of the duct.

If the rooms of my home have inconsistent temperatures, can Aeroseal improve the performance of my heating and A/C system(s)?

The Aeroseal sealing system can help improve the comfort of your home by reducing the difference in temperature levels throughout your home.

Can the Aeroseal duct sealing system reduce the noise made by the return and supply grilles in my home?

This noise is usually the result of two conditions. One is created when the ductwork is undersized and air is rushing through your air duct system. The other condition is caused when a limited amount of air is allowed to flow through the indoor coil of your heating and cooling system. Once the exact problem has been identified, your contractor can provide the best solution for noise reduction.

Can the Aeroseal duct sealing system reduce the amount of dust in my home?

Ductwork runs through attics, crawlspaces, basements, garages, and walls. Leaking return air ducts pull in dust and other indoor air pollutants and sends them to the central heating and cooling system. From there they sent to the living areas of your home. The Aeroseal duct sealing system can reduce the amount of leakage by as much as 97%, reducing dust and other indoor air pollutants from the conditioned air in your home.

What does the Air Duct Diagnostic and Inspection tell me?

Inspection discovers any obvious break in the duct work and, as the initial step of the sealing process, the Aeroseal system will establish an exact amount of leakage in the duct system. Of course, many people already know that a room or two in their house doesn’t get good air circulation because they can feel it. Or, they already know that their energy bill is high because they see it. The diagnostic measurement, provides a scientifically valid means to understand the performance of your air duct system. Many people are surprised to learn that homes typically leak 30% to 40% or more of their air through air duct leaks. We can typically seal 80-98% of the previous leakage and improve the overall system between 20 and 40%.

In a nutshell, how does an Aeroseal duct seal work?

Basically:

  • Preseal test to measure the leakage as a baseline for measuring progress.
  • Block off the registers with foam or plastic.
  • Inject an UL tested and approved aerosol into the duct system.
  • Since the air has no place to go except out through the leaks (the registers are blocked), the sealant material is deposited precisely at the air duct holes or cracks where leakage occurs.
  • A computer and sensors are used to measure and control the progress. The technology is patented from the University of California and the process is endorsed by the Environmental Protection Agency.
  • Postseal test to measure improvements.
  • Complete report and certificate printed on the spot to provide a record of improvements.

Is the sealing material used by the Aeroseal duct sealing system safe?

The sealant material consists of a water-based solution (65% water) prior to application. The dried sealant material primarily contains two chemicals, vinyl acetate polymer (VAP) and 2-ethyl-1 hexanol (2E1H). The vast majority of what is left in the duct system is VAP, which has been used in water-based paints, adhesives, and hair spray. VAP has been used in chewing gum, and has no OSHA Exposure Limit. 2E1H is a common industrial solvent and is not considered toxic by OSHA. A review of the literature showed no ill effects after long-term exposure to concentrations of 200 ppm. The largest concentration of 2E1H measured in test houses was 1 ppb (200,000 times smaller), during Aeroseal injection. The sealant is UL-listed for smoke generation and flame spread (UL 723 0,0), and additional testing by UL showed no signs of mold growth or erosion.

Does the sealant leave an odor?

The Aeroseal aeroseal duct sealing process leaves no lingering odor, and since the material does not put off gas over time, there will be no odor for the life of the product.

Can the Aeroseal duct sealing system help reduce my utility bills?

Some homeowners have saved up to 40% of their energy bills after having the Aeroseal aeroseal duct sealing system seal their central air duct system. A typical homeowner should expect to see measurable reduction in energy use for Heating and Cooling.

Is the sealing guaranteed or can I get my money back? What if it doesn’t work?

Aeroseal provides a 10-year warranty on the seals created with our process. We have enormous confidence in the quality of our seals since they are based on Lawrence Berkeley National Laboratory research and a patent through the University of California. The EPA has endorsed Aeroseal, as have numerous local energy utilities. Note: the warranty is for on-site seal failures and does not cover additional damage (e.g. an electrician that steps on a duct while running wiring), wear or tear (i.e. the shelf life of a plastic duct is passed, rodents eat into a duct, or a duct rusts out), and subsequent replacement of failed ducting. Overall, in the 85000 plus seals done to date, we have received negligible number of warranty claims.
