As the cooler season calls for the furnace to be running, it can be unsettling when it starts making noises.
While some creaks and hums are normal, loud, new, or unexpected sounds can be a sign that there is more going on than meets the eye! It’s always a good idea to investigate a new sound, especially if the furnace stops working.
Reasons
Here are possibilities of what that loud noise can mean:
- A high-pitched squeal: If it sounds like nails on a chalkboard, homeowners may have a belt issue or a problem with any of the furnace’s moving parts. Don’t just cover the ears and ignore this issue as it could lead to even more issues.
- Scraping sounds: Ball bearings may be behind this noise or the blower wheel may have become loose. If homeowners catch it early and it is the blower wheel, it may be a quick fix.
- Rattle, rattle: This type of sound typically means something is loose, such as a panel or even a screw. If homeowners can find it and are a do-it-yourselfer, they may be able to tighten it on their own.
- Popping up: While air temperature changes in ductwork can cause normal pops, loud, different, or new popping can be a sign of an older furnace’s gas burners having buildup.
- Humming noises: If that hum seems different or is more noticeable than when the furnace is just running and circulating warm air throughout the home, it could be that the blower fan is breaking down.
- Whistling air: Homeowners may have restricted airflow when they hear whistling, so check the air filter and change it to help keep warm air flowing freely.
- Anything loud: Sudden and strong booms or bangs are a concern as there may be a gas buildup somewhere in the system from a furnace issue. It is best to turn off the furnace and reach out to Van Drunen Heating and Air Conditioning team right away to prevent an emergency.
