As the air leaked from the holes, the particles stuck to the edges
My gas furnace is about five years old, plus we’ve only had our central a/c for several years. I’ve been diligent with decreasing air filters plus having the equipment professionally tested, but when I started noticing a gradual increase in weekly energy costs, I wasn’t sure what was causing it. I then realized that the a/c was making more noise than normal plus running for longer periods. There was absolutely a greater concentration of dust plus other debris floating around in the air, plus our house stinked sort of musty plus stale. Thinking that the a/c was malfunctioning, I was harshly frustrated. Thankful that the cooling equipment was still protected under warranty, I hired an Heating plus Air Conditioning professional to inspect plus repair the system. The specialist found no complications with the a/c. He then evaluated plus inspected the performance of the duct method plus discovered a whole bunch of minor holes. These flaws were allowing conditioned air to escape plus drawing in outside air. The a/c was forced to run longer to achieve control equipment settings; Outside, dirty air was spread throughout the house, drawbackly impacting indoor air pollen levels. I was a bit worried that the duct sealing process would be super high-priced plus messy. Instead, the whole job took less than several hours plus caused no disruption to our home. The specialist sealed off the supply plus return vents, plus pumped a mixture of pressurized air plus adhesive particles into the duct system. As the air leaked from the holes, the particles stuck to the edges. They gradually built up plus created an airnarrow seal.
