It involves sending highly pressurized air laced with polymer particles into the duct system
Last summer, I had a lot of complaints about the operation of the air conditioner. It seemed to run just about non stop & yet the property felt slightly boiling. Certain rooms were especially hot & sticky. The air coming from the vents had a musty stink, & there was an excessive amount of dust & allergens circulating in the air. My weekly energy bills were much higher than normal. When I noticed that my kids started to sneeze every time the air conditioner ran & realized that I was constantly suffering from headaches, I tied up professional repair. The contractor checked the inner laborings of the AC & found no problems. I am conscientious about replacing air filters & arranging seasonal repair for the cooling unit. The contractor then tested the ductwork & discovered that approximately twenty percent of the cooled air was leaking out through holes & gaps at the seams. He explained that these flaws in the ductwork were also drawing in contaminants & spreading them throughout the house. Because the maximum amount of cooled air wasn’t reaching the intended endpoint, the air conditioner was forced to toil harder & longer. The contractor recommended duct sealing. I was a bit worried that the repair would require splitting holes in walls & ceilings to access the concealed pipes. However, the contractor used a process called Aeroseal that fixes ductwork imperfections from the inside. It involves sending highly pressurized air laced with polymer particles into the duct system. These particles are adhesive & stick to edges of the many holes as the air escapes. They steadily build up to form a slender seal.
