San Francisco HVAC – Whistling Ductwork In Your Home?

whistling ductwork

Whether you live in San Mateo, Hayward, or anywhere around the San Francisco Peninsula, perhaps you’ve noticed what sounds like a whistling noise coming through ducts or vents. Is this a serious issue, and what’s the solution? Most likely it’s simply caused by restricted airflow, so relax and read the following tips.

A dirty air filter, vents in your home that are closed or blocked, or debris in ducts – any of these could cause airflow to become restricted. Start with the easiest step first to determine what may be causing whistling ductwork:

A dirty or clogged air filter. We’ve said it time and time again – change the filter regularly! Unfortunately, this is something many Bay Area homeowners continue to overlook. When dust, pollen, dirt, pet hairs, and other debris are stuck to the filter it becomes clogged, which could be the source of the whistling noise.

Vents that are blocked or closed. Heavy items such as furniture can block vents; closing off several vents also impedes the movement and flow of air to your home, which could account for the noise you’re hearing. Open the vents, and move objects that may be blocking others.

Ducts that are clogged with debris. The ductwork delivers conditioned air to your home, however they can become clogged with dirt, dust, hair, even mold or other debris that may build up over time. If you’ve accomplished the first two steps above and still experience the whistling noise, it may be time to have one of our HVAC technicians check out the situation to see if duct cleaning may be in order. Not only will the whistling noise stop if this is the problem, you’ll also experience cleaner, fresher air inside your home.
