Aeroseal duct sealing solves issues with furnace

Last year, when I hired a local HVAC professional to service my gas furnace, he noticed some problems with the duct system.  The ductwork was at least twenty years old, and had never been given any attention. There were leaks at the seams and small holes throughout the pipes.  These flaws were allowing approximately thirty percent of my heated air to escape. Because of the energy loss, the furnace was forced to run for extended cycles, experiencing excessive wear and tear.  I was also paying a lot more in monthly utility bills, and yet the house consistently felt chilly. I’d already turned up the thermostat by several degrees and had noticed drafts in certain rooms. I assumed that the duct sealing process would be messy, time-consuming and super expensive.  I imagined the HVAC contractor locating and sealing each individual hole. Instead, a process called Aeroseal was completed in a couple of hours and effectively repaired the duct system without resulting in any damage. The HVAC contractor first sealed off all of the supply and return registers, then blew pressurized air into the duct system.  The pressurized air contained adhesive particles, and as the air escaped through the various holes, the particles stuck to the edges. The particles gradually built up to create an airtight seal, without leaving behind any unpleasant smells or harmful residue. Once the process was complete, the HVAC contractor tested the duct system to verify the results and printed out a report for my records.  I now plan to have the duct professionally inspected every couple of years to protect against energy waste.
