On the list of signs you need to replace your furnace, higher than usual energy bills and uneven heating are two of the most common. However, it may not be the furnace’s fault – it may actually be the ductwork. There are a number of problems that can occur in your ductwork that can block or restrict air flow. You may have small leaks, or a bigger problem that may take extra special attention. However, no matter if the problem is small or big, it is important to have the problem remedied immediately, because a small problem can become a big problem, and a big problem can become a disaster if you don’t do something sooner rather than later. Here are some common home ductwork issues that can obstruct airflow.
One of the most common ductwork issues has to do with an obstruction. There are a number of things that can block your HVAC system’s ductwork. For instance, you may have some kind of animal or insect nest (hornets love to make their nest in ductwork) or you may have some kind of debris that is blocking the ductwork. So, it is important to inspect the inside of the ductwork and then remove the obstruction.
Another common ductwork problem has to do with a collapsed ductwork section. There are a number of reasons why ductwork can collapse. For instance, the ductwork may have been constructed in a shoddy manner, or the ductwork may simply be old. Not only that, but old ductwork can become brittle and screws can become loose, which can be quite a nasty combination. In fact, if you are noticing a strange sound coming from your ductwork, this may be a sign that you need to replace a certain section of the ductwork.
Next, you may also have a leak in your ductwork. Leaky ductwork can cause your system to become inefficient and it may cause your home to have erratic temperature changes. In order to find a leak, you can usually use a flashlight to see if there are any rips or tears in the ductwork. A big air leak can significantly reduce air flow and it can cause some rooms in your home to be much colder or warmer than others. In order to patch an air leak, you can use an epoxy resin and some plumber’s tape. After you patch the leak, you may notice that many of your problems will go away.
Lastly, another big issue to look out for is loose insulation. Insulation can become loose and it can start to really block the insulation’s ability for air to flow throughout the system. If you notice any sections of loose or damaged insulation, you may simply have to remove that patch of insulation and replace it. At the end of the day, insulation is an important component of your ductwork, so it is critical to remedy any problems before they become bigger problems. Insulation is important, because it maintains airflow and it can make your ductwork system work much more efficiently.
