Leaky Ductwork? Don’t Look Now, but Duct Tape Has Just Been Outclassed

Despite its name and formidable reputation, duct tape is not the best option when it comes to sealing leaky ductwork. That title belongs to Aeroseal, a state-of-the-art duct sealant technology that aims to save consumers over $5 billion each year. The Department of Energy estimates that American households lose anywhere from 20%-40% of its conditioned air through leaky ductwork.  For years, the only leakage solutions were ineffective caulks, plugs and, yes, duct tapes. Until now.

Recognizing the major cash and energy sink created by the leaky duct epidemic, the Department of Energy and the Environmental Protection Agency formed an R&D program (as shadowy government agencies are wont to do) with the directive of creating an advanced and affordable end to this epidemic. The result was Aeroseal, a true modern marvel of the HVAC industry.

How does it work?

Aeroseal is essentially “adhesive air.” A sticky particle-filled mist is introduced into your system by a certified Aeroseal technician and then blown by a fan through the ductwork. Pressure maintained within the ducts causes air to accelerate as its exits from the leaks. Aeroseal particles are designed to pile up at these leak sites, spanning and finally sealing holes up to 5/8 of an inch wide, without coating the ductwork. This patented process begins and ends by with a full diagnostic evaluation, so you’ll have in your hands exhaustive evidence of precisely how much Aeroseal has improved the efficiency of your duct system. The average energy savings per Aeroseal household per year is around $850!

Still not sold?

Aeroseal won a “Best of What’s New Award” from Popular Science magazine in 2011 and the Department of Energy rated it as one of the most beneficial American technologies of the past 35 years. But, if you’re still skeptical of these statistics and awards you’ve never heard of, just listen to the findings of this declassified experiment:

In what must have been an expensive, but utterly spectacular day at the lab, the Department of Energy concluded that if a standard refrigerator holds 25 cubic feet of air and your ductwork is leaking just 100 cubic feet of air (a conservative estimate), you are essentially hurling four fridges full of precious, conditioned air out the window for every minute your HVAC system is running. How’s that for a visual?

For the hardcore loyalists out there, don’t worry, you can still use duct tape to patch that hole your dog chewed in the futon or to reattach the bumper to your rusted out pick-up, but when it comes to caring for your home’s ductwork, ditch the tape and catch the misty, sticky wave of the future with Aeroseal.
