Ducts are things that most people don’t really think about very often. Truthfully, that’s not very surprising. Ducts are simple, uninteresting, and often unseen. That doesn’t make them any less important, however. Ducts are the reason that your central air and heating is even possible. In this article, we’ll take a look at why it’s important to take care of your ducts with duct sealing and what can happen if you don’t.
The Vulnerability of Ducts
Though most ducts are comprised of sheet metal, they are surprisingly thin in many areas, especially at the junctions where the different sections meet. This makes ducts quite prone to developing leaks. Though these leaks are usually quite small, if there are enough of them they can cause quite a bit of damage. The US Department of Energy has stated that the average home heating system loses as much as 30% of its heat to leaks in the ductwork. That translates to a staggering amount of money wasted each year, as almost a third of the system’s heat output leaks out of the ducts before reaching its destination. That’s where duct sealing comes in.
Duct sealing is a process by which the ducts are inspected and sealed to prevent leaks and other issues. First, the technician will visually inspect each section of the ductwork for leaks and other issues. In addition to wasting quite a bit of heat, leaks in the ducts can let in moisture and dust. This promotes mold growth, which releases spores that can lower indoor air quality and make people sick. Once the leaks are found and closed, a number of different chemicals can be applied as antiseptics. This kills any viruses or bacteria that might be lurking in the ducts. Though you may be tempted to try and seal the ducts yourself, it’s not a good idea. Professional technicians possess the tools and knowledge to find any possible leaks and seal them. If you try it yourself, it is very likely you will miss some of them.
