Have Noisy Ductwork? Know when it’s Normal and when it’s Time to Call a Pro

5.0 Rating

small_2512086374The ductwork in most St. Louis area homes produces some level of noise whenever the air conditioner is operating. This noise typically blends in to the normal background noise of your house. However, if the noises from your ductwork become significantly louder, or if you’re hearing different noises than usual, it could mean there is a problem with your air conditioner. So let’s go over various noises you might hear from your ducts and how to know when noisy ductwork means it’s time to call a pro!

Some noise from your ductwork is completely normal

As we mentioned above, hearing some degree of noise from your ducts is completely normal. One reason for this is that the blowing and rumbling sounds from your air conditioner’s air handler can easily carry through your ducts and out of the return and supply registers in your home. Another reason is that temperature differences between your ducts and the conditioned air that flows through them can cause your ducts to slightly expand and contract. When this happens, you might hear some popping or clicking noises. Again, these noises are completely normal.

When noisy ductwork can indicate problems with your air conditioner

If you have any questions about noisy ductwork, or if you’d like a cooling system serviced or installed in your home, contact Jerry Kelly, your St. Charles, MO, air conditioner service company. We service the St. Louis area, including towns like St. Paul, St. Peters and Town and Country.
