Furnace Making Gurgling or Bubbling Noise

This noise is more common with high-efficiency furnaces. That’s since they emit fumes dissimilarly older furnaces, and the process can create some moisture. If your furnace is having issues discharging this water, it can make gurgling or bubbling sounds.

Furnace Making Banging Noise

It’s not a good indicator when your furnace is making a banging sound. It might mean a few things.

Haven’t scheduled maintenance recently and your furnace is producing a banging sound when beginning? Its burners could be dirty. Dirty burners can delay ignition, which results in gas accumulating in your furnace.

All that accumulated gas can create a banging or booming sound when your furnace eventually does ignite. But this is more than just an irritating noise, because the accumulated gas is exploding inside your furnace. This can crack your furnace’s heat exchanger and create a deadly carbon monoxide leak.

Your ductwork can also produce banging sounds when your furnace switches on, because the metal is expanding and contracting.

We advise first inspecting your furnace’s air filter and replacing it if it’s filthy. Next, make sure you don’t have too many vents closed in your house, as it can throw off air pressure.

If neither of these methods fix the issue, your ductwork may be dirty or undersized, which will be a need for assistance from a pro HVAC technician.

Furnace Making Humming or Buzzing Noise

If your furnace is buzzing or humming, it’s a flag there’s an electrical issue. This is most usually seen with a dying blower fan motor, which will produce a loud buzzing noise when your furnace begins to heat. It can also mean there’s a problem with the capacitor or transformer. All three of these troubles need support from an experienced heating and cooling company like Dearing's Service & Solutions.
