Furnace Whistling in Sherwood, AR

Although advances in furnace technology allow your furnace to run quietly, it will still make some noise during operation. However, certain noises, like a whistling sound from your furnace, are abnormal and require further inspection.

Why Is My Furnace Making a Whistling Noise?

If your furnace is making a sound akin to a high-pitched tuning fork, this could indicate that air is escaping from somewhere in the system. There might be a loose connection in the ductwork, or you may have added a new component to the furnace that possesses more power than the previous component, affecting the airflow. This often happens if a homeowner installs a new or rebuilt fan.

Your furnace might make this high-pitched whistling sound because you have a low return airflow. Your system’s blower attempts to suck in a certain amount of air, but something is impeding its ability to do so. The result is increased pressure and velocity within your ductwork, creating that unpleasant whistling sound.

How to Keep Your Furnace From Whistling

There are some preventative steps you can take to decrease the whistling sound. Make sure that the supply vents in your home are not shut off. Open the vents, even in rooms that you don’t use. Ensure that furniture or household items are not covering the vents.

Keeping the doors open throughout your house is beneficial. This allows the free flow of air throughout your home.

While there are some preventative measures you can take, for safety reasons, it’s best to have Bill Lea Service HVAC professionals diagnose and fix the whistling sound from your furnace.
