Duct Sealing & Cleaning

Research has shown that the average home in the United States today loses 20% to 40% of its heated and cooled air through leaks in the duct system. Many energy auditors are finding the situation even worse for mobile home owners. Poor assembly, the units’ design for mobility and other factors typically result in HVAC systems that leak as much as twice that of an average stick-built home.

Energy leaks could be costing Americans $5 billon every year.

Who knew leaks could be costing Americans $5 billion every year? And that’s not water leaks — it’s leaks you can’t even see. Typical air duct systems, both residential and commercial, typically lose 25-40 percent of heating and cooling energy, accounting for billions added to utility bills.

But what if there was a simple mist that could seal thousands of leaks in 4 to 8 hours, saving a home owner on average $600 to $850 a year on his or her heating and cooling costs? Thanks to a breakthrough technology developed at the Energy Department’s Lawrence Berkeley National Lab, such technology exists. Aeroseal LLC, a start-up that licensed the technology, has now made the technology available to thousands of home owners and business owners concerned with high utility bills and sustainable living.

Aeroseal’s airborne adhesive particles are injected by Aeroseal technicians into a HVAC (heating, ventilation and air conditioning) duct system at low cost, low labor requirement and minimal disruption to building occupants. The revolutionary energy efficient technology recently won in the Home Technology category in This Old House magazine’s top 100 Best New Home Products.

“Leaky air ducts are responsible for a huge energy loss problem in America and having the aeroseal solution made available for the first time to many home owners is very exciting to see,” said Thomas Baker, building technology editor for the magazine. Space heating and cooling drive residential energy demand and utility costs — it accounts for 54 percent of a home’s energy consumption.

Before the Aeroseal technology is injected, technicians block furnaces, fans and grilles so that the adhesive particles will be directed towards cracks, leaks, and holes. The technicians then inject the aerosolized vinyl polymer particles, of two to 20 micrometers, into a pressurized duct system. The particles stay suspended in the air stream until they reach the leaks, where they are deposited and build up at the leak edges until the leaks are sealed. Specialized software allows both the technician and customer to view the process in real time.
