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

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:
Leaky ducts in a commercial building contribute to:
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.
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.
