When my furnace started running non stop and failing to handle demand, it took me awhile to realize that holes in the ductwork were the problem.
Although I am good about scheduling professional service for the heating system, I tend to forget the duct system.
Since they’re mostly concealed inside the walls, ceilings and attic, I don’t pay those essential pipes enough attention. I eventually googled all the issues I was having with the furnace. I figured out that spotty comfort, longer running times, unpleasant odors, excessive air contaminants and higher energy bills could all be blamed on leaking ducts. I then contacted a local HVAC contractor to provide duct sealing. I expected the process to create a huge mess and disruption to my home. I assumed the HVAC contractor would need to locate and patch the holes one by one. Instead, the HVAC contractor used an innovative and proven technology known as Aeroseal. The technician first sealed off all of the supply and return vents. He then pumped highly pressurized air, laced with polymer adhesive particles, into the duct system. The air naturally escaped through all the various holes, cracks and imperfections. As this air escaped, the adhesive particles stuck to the edges and gradually built up to create an airtight seal. The whole process took about four hours, and there was no upheaval to the home. There was very little residue left behind in the ducts. Once the service was complete, the HVAC contractor tested the ducts and verified the results. The process can be expected to provide a reliable seal for forty years and is warrantied for ten years. It’s entirely safe, creates no odors, and has definitely paid for itself through much lower energy bills.
