Does your ductwork make peculiar noises? Perhaps it is starting to cause sleeping problems for you. After all, it is no fun falling asleep and later getting startled by noises. If you have young children, this phenomenon may also be affecting them. The sounds you're hearing may not be a sign that the ductwork is damaged, but you may need to make some amendments to your ductwork if you want the noises to cease. For example, some ductwork may make a whistling sound due to low-level air leakage. The following points will help you to better understand common reasons why are ducts can be noisy. 

Duct Thickness

Thick ducts are resistant to bending. The noises you are hearing may be because you have thin ducts that aren't as effective in handling air from your furnace or air conditioning system. Robust heating and cooling systems have to transport warmed or cool air throughout a property, and sometimes, they exert high levels of pressure as they perform. Thin ducts may be more susceptible to bending during this process. This does not mean that the thin ducts will get damaged, but the bending of the ducts can cause unpleasant noises such as popping to occur. 

Duct Shape

Ducts come in a variety of shapes. Circular and rectangular-shaped ducts are common. Some people find it shocking that a simple change, such as a new duct design, can result in their HVAC systems running quieter. If you currently have rectangular ducts, making a switch to circular ducts could result in quieter duct operation. 

Duct Condition

Perhaps your ducts have deteriorated. They may no longer have creases in them. You may even have a duct design that does not feature creases. Upgrading to a creased design can aid in reducing the aggravating noises. This is because the creases in ductwork is a feature that gives the ducts flexing room during their operation. 

An HVAC contractor is a good resource to use to address the issues with your ducts. They can also determine the best approach to fixing the issue to ensure that you can look forward peaceful nights of sleep. They can inspect your ducts, and they may be able to suggest a different remedy for fixing the noisy ductwork than replacement. For example, if your ductwork is in excellent condition, the professionals may suggest trying insulation since the noise is your only complaint. The insulation can serve as a noise barrier.
