Rooms furthest away from your heater and/or air conditioner should be heated or cooled to the same level as the rest of your home or business. If this isn’t the case, you have a problem.  Do certain air registers have little to no air flow? A common cause is faulty or damaged ductwork, and you probably have leaky ducts. Getting an airtight seal throughout the HVAC system can be difficult for even new installations when the ducts are exposed and easy to access during new home construction. Experienced and skilled installers may have been in short supply leading to less than optimal results. In fact, Energy Star states this about A/C systems: “More than half of new systems in U.S. homes do not perform to their rated efficiency as a result of improper installation.”

What potentially went wrong? A common culprit is the need for thorough and proper application of mastic A/C putty where joints meet and need its sealant properties. It  is essential to seal the system for maximum efficiency. Imagine that your HVAC unit is the heart and supply ducts are the artery blood vessels, in this case, pumping air to the far reaches of the system. Return ducts are the veins carrying air back to the heart of the system. If we had leaks everywhere in our bodies, there would be serious health consequences. We wouldn’t be as healthy as we should be. The same goes for air conditioning systems. A further complication is that leaky ducts can pull mold, dust and other pollutants (Think rodent droppings that dry out and become part of the attic air supply. Yuck!) into your home, aggravating allergies and potentially fouling the air with smells. According to Burke Treidler and Mark P Modera, “Unfortunately, the problems with duct systems are not widely recognized within the construction industry and there are no strong economic incentives to solve them. Duct system performance is not evaluated and HVAC contractors overcome duct system shortcomings by installing oversized equipment. Currently, most duct systems are installed with minimal insulation and by methods that give little thought to insuring proper sealing,” ( In the HVAC world, we will suffer higher power bills, improperly heated and cooled rooms, and unnecessary wear and tear on our expensive equipment. What to do?

Duct leaks can be difficult to find with much of the ductwork hidden in walls and ceilings of your home or business. Sealing these HVAC system leaks used to be challenging, but no more.Don’t resign yourself to suboptimal performance and higher power bills. Solve this energy-wasting problem in only four to eight hours using Aeroseal technology.

Aeroseal technology was funded by the DOE’s Office of Energy Efficiency and Renewable Energy together with the California Institute for Energy Efficiency, the EPA and the Electric Power Research Institute (EPRI) and developed at Lawrence Berkeley National Laboratory. Now the technology is commercially available to trained and certified technicians offering the immense benefits of the Aeroseal system of leak sealing. According to the Lawrence Berkeley National Laboratory, “Aeroseal uses airborne adhesive particles to seal leaks from inside the ducts reaching previously unfixable leaks at low cost and minimal disruption to building occupants. Sealant particles of two to twenty micrometers are injected into a duct system while specialized software allows both technician and customer to view the process in real time. Prior to sealing, furnaces, fans and grilles are blocked, directing all adhesive particles towards cracks, leaks, and holes. Aeroseal’s technique has been proven to seal from 70 to 90 percent of duct leaks and is guaranteed to last for ten years.” This is a potent solution that we’re happy to offer our clientele. Save money, enjoy a more comfortable and reliable temperature, breathe cleaner air, and even be a better steward of the environment by being a little “greener” via Aeroseal.
