Have Noisy Ductwork? Here are 5 Ways to Reduce the Noise
Nobody likes noisy residential ductwork. But if you’re not an HVAC professional, it can be tough to fix. This article covers some of the most common causes of noisy ductwork and their solutions to help you get back to enjoying your home.
Check These Common Issues First
The first thing to know is that noisy ductwork isn’t always related to the ductwork itself. Your problem could be a result of:
- Closed vent dampers
- Sagging or bent flex ducts (which make it harder for the system to move air)
- Dirty air filters or ducts
These problems are the easiest to fix. So you should try opening your vent dampers, fixing your flex ducts, and replacing your dirty air filters before proceeding.
Fix Your Static Pressure
Residential ductwork with high amounts of static pressure are noisy. That’s because when the pressure in these ducts is too high, they can’t adequately process the amount of air you’re sending through them.
You may be able to fix this problem by adjusting the fan speed. If you lower the fan speed, it could reduce static pressure in your system and fix your noise problem.
You may also need to add ductwork or a bypass duct to your home. Doing this will help the system process the air that it receives more effectively.
Finally, you may need to add or expand grilles and registers. If your system isn’t getting enough return air, that could be the source of your noise troubles.
Consider a Variable Speed Blower
You may also want to consider upgrading to a variable speed blower. These systems use fans that run at a lower speed, which varies based on your heating and cooling needs.
The bottom line is that variable speed blowers move less air through your ducts so their noise levels can often be quite a bit lower than what you’d get from a standard HVAC system – even if your ductwork remains exactly the same.
