Last winter, my local section experienced record low un-even temperatures.
All of us dealt with downside digits, brutal wind chill and constant snowfall.
The forecast was always calling for snow flurries and blizzard conditions. My apartment felt cold. Adjusting the temperature control didn’t solve the problem. The furnace seemed to be running non stop but not accomplishing anything. I noticed that particular rooms were colder than others, and there seemed to be a greater amount of dust floating in the air. When I was faced with a significant increase in my biweekly heating bill, I called a local Heating and A/C contractor to check out the furnace. He looked everything over and found a minor accumulation of dust within the inner workings. He then inspected the air duct and discovered that approximately 25% of our heated air was leaking out through holes and cracks at the seams. All of us needed duct sealing. I was a bit concerned about the process. The duct plan is made up of a network of pipes concealed inside the walls, ceilings and attic. I wasn’t sure how the professionals could access them without causing a big mess and enjoyable deal of disfigure. The contractor then explained a fairly recent innovation called Aeroseal duct sealing. They can now service flaws in the ducts from the inside. First, the contractor plugged off all of the supply and return vents. He then hooked up a device that pumps pressurized air into the pipes. This air contains polymer particles that are non-toxic and adhesive. As the air escapes through the holes and cracks, the particles cling to the edges and gradually build up. It takes a couple of minutes to ensure an airslender seal. The contractor once again inspected the operation of the ducts to verify the results. The Aeroseal process is warrantied for more than nine years.
