If you’re running your furnace full time, you’ve likely heard a few odd noises coming from the system. Their cause can range from mostly harmless to serious; you’ll need to speak with a heating contractor for an official diagnosis. When they come out, you can inform them if you’ve heard one of the following sounds.

The Meaning Behind Common Furnace Noises

1. Whistling

If you hear whistling around your home while the furnace is running, the sound is likely coming from your ductwork rather than the unit. When you have small cracks or perforations in your ducts, air will create a shrill sound as it escapes. You need to find the hole and patch it; escaping air prevents your system from efficiently heating your home. If the noises are coming from your furnace, you may be dealing with more serious airflow issues that require a heating contractor.

2. Booms & Bangs

Booming and banging may simply be your ductwork expanding and contracting from the heat, which is perfectly normal. If it’s accompanied by jumbling noises, you may have debris in your ductwork and should have an HVAC contractor clear it away. If these noises come from the furnace, it could be issues with the ignition or combustion within the tank.

3. Tumbling

Any tumbling noises inside of your furnace usually mean that loose parts are bouncing around. They could be whole parts or pieces from a broken one. Debris could also be the culprit. Furnace cleaning through a heating contractor will eliminate any foreign substances. As well, the expert will have a better view of the unit and will see if any part failures have occurred.
