Complaints with furnace caused by leaky ducts

He then pumped highly pressurized air into the system.

My furnace is only six years old. I’ve been diligent about replacing air filters and scheduling professional tune-ups every fall. I spent extra for a top-of-the-line heating unit that features a 96% SEER, adaptable-speed technology and an ENERGY STAR rating. I was not happy when I had complaints about the operation last winter. I first noticed that specific rooms in the house were significantly warmer than others. I gradually became aware that the furnace was running for much longer cycles and struggling to manage demand. There was an abundance of dust circulating in the air and an unpleasant smell coming from the vents. I hired the same contractor who handles the maintenance of the furnace for repairs. When I explained my concerns with the operation of the heating system, he immediately suspected the ductwork as the problem. A testing of the duct system revealed that approximately twenty-five percent of the heated air was leaking out through cracks at the seams and small holes. Because the maximum amount of heated air was failing to reach the intended destination, the furnace was working much harder and failing to achieve ideal comfort. These same imperfections in the ductwork were drawing in unconditioned air and spreading allergens throughout the house. I was a bit worried that the duct sealing process would involve cutting holes in the walls and ceilings. The majority of the pipes are entirely concealed. The HVAC technician explained that they utilize an innovative procedure that treats the flaws from the inside. He began by closing off all of the supply and return registers. He then pumped highly pressurized air into the system. The air contains polymer particles that are non-toxic yet adhesive. As the air leaked out through the holes and cracks, the particles clung to the edges and each other to create an airtight seal. The entire process was guided by a computer program that then verified the results.
