When we think about indoor air quality, we often focus on surface cleanliness, air purifiers, or even houseplants. But there’s one hidden part of the home that can have a huge impact on the air you breathe—your ductwork. If your ducts are damaged, you could be unknowingly exposing yourself and your family to a range of harmful contaminants every time the heating or cooling system kicks on.
Damaged or leaky ducts can develop cracks, holes, or loose connections over time due to age, poor installation, or even pests. These breaches create pathways for contaminants to enter your duct system, which then circulate throughout your home. Among the most common—and most concerning—are dust, sawdust, pest-related debris, and fibers from various types of insulation.
