Duct sealing makes a huge difference in comfort and air quality of home –

Although I’ve always been good about taking care of the furnace and air conditioner in my home, I’ve totally neglected the duct system.  I simply never gave it a thought. I hire professional maintenance for the heating unit in the fall, and repeat the process in the spring for the cooling unit.  The HVAC contractors never mentioned upkeep for the ductwork. I eventually started to notice a rise in monthly energy bills, decrease in comfort and issues with indoor air quality.  During the winter, I kept raising the thermostat setting and yet the house felt chilly. There were unpleasant cold spots in certain rooms, as well as drafts. The heated air smelled bad, and there was a lot more dust floating around.  I finally called up a local HVAC contractor and explained the problems. The technician inspected the duct system and informed me that there were numerous holes and leaks at the seams. These imperfections were allowing the heated air to escape and bringing in unconditioned and polluted outside air.  This forced the furnace to struggle and run longer, trying to keep up with demand. I hired the HVAC contractor to complete a duct sealing process. He sealed off all of the supply and return registers and pumped a combination of pressurized air and adhesive particles into the ducts. As the adhesive particles escaped through the holes, they built up to gradually create a tight seal.  The duct sealing process was completed quite quickly, with no damage to the system or disruption to my house. The HVAC contractor then tested the ducts and verified the results.
