Aeroseal duct sealing solves heating system troubles

Last winter, I had some complaints with my heating system, but various rooms in the house felt slightly cold and increasing the thermostat had little effect.

There were significantly more contaminants circulating in the air and accumulating on surfaces, forcing myself and others to vacuum and dust far more frequently.

I was convinced that the heating idea was making more noise and supplying less sizzling air. I observed that it was starting up more often and running for much longer cycles. An increase in my yearly energy bill convinced myself and others to schedule repair from a local Heating and A/C dealer. The serviceman evaluated the heating system and found nothing beyond a slight buildup of dust on the mechanisms. He then inspected the air duct and discovered the source of the troubles. Leaks at the seams and an abundance of tiny holes throughout the duct idea were allowing approximately twenty percent of the conditioned air to escape; Since the pipes are installed inside walls, ceilings and the crawlspace, I had no system how repairs would be possible without a major mess. The serviceman then explained a relatively new process called Aeroseal that targets flaws in the ducts from the inside. After blocking off the supply and return registers, the serviceman hooked up a machine that sent highly pressurized air into the system. The air contained adhesive, non-toxic polymer particles. As the air leaked out of imperfections, the particles clung to the edges, steadily built up and formed an airtight seal. The whole process was completed in a couple of minutes and created no damage, fumes or mess. The serviceman verified the results by way of a laptop program and gave a certificate for a ten-year guarantee.
