Ducts get dirty by trapping contaminants and objects inside your ducts that come from outside air and inside your home’s walls.
Leaks in your ductwork let air that blows into your attic, walls, or crawl space get sucked into your ducts and then blow throughout your entire home.
A telltale sign of leaky ducts is consistent layers of dust on furniture and flat surfaces during periods when your windows are most often shut.
When Duct Cleaning Makes Sense
Sometimes it’s necessary to have your ducts cleaned. In fact, we refer ducts for cleaning when we see signs of serious contamination. However, most times duct cleaning is not required prior to duct sealing.
