At first glance, the ductwork for your heating system may seem like an incredibly simple construction. Truth be told, it kind of is. Ducts are usually simple rectangular tunnels of sheet metal, with the sole purpose of directing air throughout the house. Being simple doesn’t mean that they are trivial, however. The quality of your ductwork has an immense effect on the quality of your home heating. Let’s take a look at a couple of examples.
Your ductwork is likely to develop a leak here or there sooner or later. Ducts, especially rectangular sheet metal ones, expand and contract with the heat of the air moving through them. This flexing and fluctuating will eventually cause small cracks to form in parts of your ducts. One or two small ones aren’t too big of a problem. However, faulty ductwork has the potential to form many more leaks than usual.
The US Department of Energy estimates that forced air heating systems lose between 20 and 30% of their heat on average to leaks in the duct work. That’s almost a third of your system’s heat that is being lost during operation, for which you are still paying. This is where faulty ductwork can have a major effect on your home heating. Even though the USDE makes no distinction between the quality of the ductwork in those statistics, it’s a fair assessment that faulty ductwork is far more prone to more and larger leaks.
Mold requires darkness and moisture to thrive and spread. If mold were to ever take root in your ducts, it could release spores into the circulation system. These spores can provoke allergy attacks, make you sick, and generally lower your indoor air quality. Normally, ducts are specifically designed to keep moisture out. Faulty ducts, however, are often not sealed properly. This can allow moisture into the ducts, causing mold growth along with a host of other issues. This doesn’t affect the quality of your heating right away, but it will cause the degradation of your ducts.
