Duct sealing is necessary

The whole procedure takes a couple of hours, causes no damage and leaves behind no residue or odor

As soon as I started up the furnace last winter, I noticed some concerns. There seemed to be a lot more dust and unpleasant smells coming from the vents yet less heated air. As the outdoor temperature dropped, I kept raising the thermostat level. The house felt chilly, and the furnace couldn’t keep up. Certain rooms were especially cold. I should have called for repair immediately, my that time of year is always hectic. By the middle of January, I was extremely unhappy with the performance of the furnace as well as the cost of my utility bills. I finally scheduled professional service. The technician looked over all components of the furnace and tested the duct system. I hadn’t considered that the ductwork might be to blame for all of the problems. The testing revealed that approximately 25% of the heated air produced by the furnace was escaping through various leaks and holes. Because the maximum amount of air wasn’t reaching the rooms in the house, the furnace was struggling to meet the thermostat setting. The longer run times added to wear and tear and caused the higher heating bills. I wasn’t sure how this issue could be fixed. With the ductwork mostly hidden inside walls, ceilings and the crawlspace, I was worried the process would require some major renovation. Fortunately, there is a duct sealing process that works from the inside. Polymer adhesive particles are pumped into the ducts by way of highly pressurized air. As this air leaks from the holes, the particles cling to the edges and gradually build up. The whole procedure takes a couple of hours, causes no damage and leaves behind no residue or odor. It’s also perfectly safe and non-toxic. After it was complete, the technician once again tested the ducts to verify the results.
