Are Leaking Ducts Costing You More Than You Think?


You can see a water leak, but an air leak is invisible. Duct leaks can be difficult and costly to find with ductwork hidden between the walls, floors, and ceilings of any residential home or commercial building.

The older, traditional use of mastic (a messy caulk-like substance) or taping of leaks not only is less effective than Aeroseal, but also can be very labor-intensive and expensive and can only be applied to ducts with physical access.

Other substances break down over time, but the Aeroseal sealant does not and even has a 10 year warranty to back it up.

Aeroseal pinpoints and covers leaks, in roughly an hour, from the inside out with a success rate of up to 98%. Aeroseal is the most effective, affordable, and viable method of sealing air duct leaks on the market.

In commercial buildings most ducts have none to very limited physical access, which lends Aeroseal to be the only solution in the market which can guarantee results and improvements.




Aeroseal technology will improve your air quality.

E&J Geothermal Inc. provides modification, duct-sealing and zoning services for all ducting systems in residential and commercial structures.

E&J Geothermal Inc. installs Aeroseal sealant.

Stay comfortable all year long with an Aeroseal ducting system.

The measured result of a typical Aeroseal air duct sealing process is shown below:

Aeroseal can reduce duct leakage by up to 90%, reduce your energy use by up to 30%. Aeroseal has also been shown to dramatically improve comfort and homeowner satisfaction with their heating and cooling systems.

Leaky ducts in a residential home contribute to:

  • Loss of cool and warm conditioned air to the outside or unconditioned spaces of your home resulting in high energy bills
  • Even the most energy-efficient heating and cooling systems not performing at its best
  • Forcing your system to work harder and wear out sooner, costing you yet more money
  • Excess humidity levels that can lead to costly home repairs
  • Hard to heat or cool rooms leading to discomfort
  • Musty odors and other indoor air quality (IAQ) issues

Leaky ducts in a commercial building contribute to:

  • Loss of air resulting in significant increase in fan power energy use and over high energy bills
  • Air contamination due to duct leakage in hospitals and doctor’s offices
  • Air balance issues and problems complying with the Air Flow building codes
  • Poor ventilation in high rise buildings such as hotels and multifamily dwellings resulting in unpleasant odors
  • Unable to keep non-smoking sections of the building uncontaminated from cigarette smoke
Breathe easier with Aeroseal sealant.

Energy Savings

Does your home or building experience high energy bills and/or a constantly running system?

Over 90% of existing buildings located throughout North America have air duct systems that contain small holes and cracks that reduce the level of comfort and increase heating and cooling costs.

Leaks are caused by a variety of factors including the age of the dwelling, type of construction, type of ductwork and local building codes.

Repairing and patching leaks in HVAC duct systems saves cooling, heating, and fan energy. In air-based systems, ducts deliver all of the heating and cooling to conditioned spaces. Any duct leakage translates into extra air that must be supplied so sufficient heating or cooling reaches the conditioned space. This not only increases effective heating and cooling loads, it also increases fan energy due to increased flow and/or run time. Sealing duct leaks reduces the amount of heated or cooled air the supply fan must handle to deliver the same amount of air to the conditioned space.

Healthy Space

Does your home or building experience air quality problems, excessive dust, and or air contamination/odor issues?

Duct leakage may be causing your indoor air quality problems.

A good transmission gets power to all the wheels of a car. Just like a good air duct system gets air to all the rooms of your home or building.

In Residential buildings, the problem with leaky ductwork is that air can not only leak out of you HVAC system and air ducts -- untreated and unclean air and contaminants from the crawlspaces, attic and other place can actually be pulled in to the air you and your family breath. Since so many air duct systems leak and pull bad air in (we find 20 to 40% leakage in 3 out of 4 homes we visit), poor air quality is a problem that many homes have.

In commercial buildings, the problem with leaky ducts in return ducts and ventilation shafts creates air contamination and results in odor issues and unhealthy indoor environment.

Ensure you and your family are breathing healthy air every day with an Aeroseal sealant system.

What are the benefits?

  • Airtight savings: The money formerly leaking out of your ducts will stay in your pocket longer
  • Airtight comfort: Your hard to heat or cool rooms will have more even temperatures and be more comfortable
  • Improved air quality: You will see a reduction in dust and humidity, along with fumes and other odors
  • Reaches everywhere: Seals leaks nearly impossible to reach using other methods
  • You’ll be a small part of a bigger solution: A reduction of the amount of air pollution created from generating less energy
  • Solve your building air flow and ventilation problems
