If you’re asking this question, you’re probably already familiar with the primary reason that people get their ducts sealed. Duct sealing is normally done to find and close any leaks that may have formed in the ductwork, either from poor insulation or everyday wear and tear. Duct leaks can waste a huge amount of energy and money. In fact, as much as 30% of the average home heating system’s output is lost to duct leaks, according to the US Department of Energy. However, there are other issues that duct sealing can help with, including indoor air quality. Let’s take a look at how sealing your ducts can increase your indoor air quality.
Airborne Contaminants Get Pulled Into Your Air Ducts
The air in your home is actually teeming with microscopic contaminants, though you may not notice it much. You’re inhaling dust, pollen, dust mites, insect and pet dander, and even viruses and bacteria on a regular basis, and these airborne contaminants love to collect in the ducts of your home. When you turn the heater or air conditioner on, you’re actually helping to circulate these contaminants around the house.
How Duct Sealing Helps
So, how can duct sealing actually help get rid of these contaminants? Professional mastic duct sealing ensures that you’re not pulling in dust and other debris from the spaces in between walls and in the attic. But it’s not just particulates. For example, if a leak allows water to get into the ducts, it creates the perfect environment for mold growth. When the mold grows, it releases spores that can be quite harmful to your health. Duct sealing prevents moisture from entering the ducts, drastically lowering the likelihood of a mold-friendly environment being created in your ducts.
