Why Is My Furnace Making Weird Noises?

Posted on: December 29, 2017

Is your furnace making some odd rumbling, clanking, or humming sounds? We think your furnace might be trying to tell you something! But what, you say? Follow along with the certified heating team at All American Home Services to find out.

What Do These Noises Mean?

It’s safe to say that no matter what noise you’re dealing with, it’s not trying to tell you anything good. Unfortunately, most furnace noses can be traced to a particular problem or another, so in a large majority of cases, odd sounds are going to indicate a need for professional repair.

Now that said, what service you need and when you need it will depend a bit on what kind of sound you’re hearing. Let’s cover some of the most common sounds a furnace in distress will make, and when you should call on a pro:

  • Squealing or squeaks – These sounds will most often mean that a bearing or belt is wearing out, or that a bearing lacks proper lubrication. The problem most commonly occurs in the fan assembly or the blower motor. This needs service as soon as you can schedule it, but thankfully out of all the problems you could be having, this is one of the least problematic and least costly to fix.
  • Metal grinding or rattling – A loud grind or clank means a component is either severely damaged or that it has come loose. This is one sound that can be really problematic. The longer the part is left to dangle and clank, the more damage it is going to do to the system as a whole. You’ll want this fixed as soon as possible, and we recommend calling in emergency service.
  • Buzzing and humming – Loud buzzes or hums, sometimes accompanied by rapid clicking, are electrical sounds. These sounds indicate that a connection is loose or that a component in the system is overloading. These can be problematic, as you might expect! Keep particular care in noting any odd or pungent odors, as these will tell you if the parts are burning up. Either way, it’s best to shut the system down until it’s serviced.
  • Low bangs in a gas furnace – Low, deep bangs in a gas furnace system are most commonly due to a misaligned or dirty pilot burner. You can try to remedy the issue easily by shutting down the gas furnace and cleaning the burner to clear flow. If the problem persists, it may be a more serious issue with the burner assembly or pilot, and you’ll want to have a furnace repair expert over as soon as possible.
