Why Is My Furnace Making Weird Noises?
Is your furnace making weird noises, like some odd rumbling, clanking, or humming sounds? Strange sounds from your furnace aren’t just annoying, they are often an indication that something isn’t working right. So, if you’ve noticed any weird noises from your furnace lately, you should take note. Fortunately, our HVAC experts at Iceberg Home Services are here to help, and we’ve put together this guide covering common furnace noises and what they mean.
Common Furnace Noises & What They Mean
While you can expect some normal furnace noise when in use, it’s safe to say that a furnace making loud noises while running isn’t a sign of something good. Unfortunately, most furnace noises 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.
The service you need 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 professional for repairs:
- Squealing or squeaks: Furnace squealing noises will 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: If your furnace is making a rattling noise, this means a component is either severely damaged or 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, hums, or furnace clicking sounds, are electrical sounds. These sounds indicate that a connection is loose or that a component in the system is overloading. 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: If your furnace makes a banging noise when it shuts off, take note. Low, deep furnace banging noises in a gas 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 the 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.
Why You Shouldn’t Ignore a Noisy Furnace
When your furnace starts making loud noises, it’s trying to tell you something. Loud noises are not standard, so don’t ignore them. If you leave a furnace noise problem unaddressed, you run the risk of the problem worsening. For instance, in the case of furnace squealing noises, you may be dealing with a loose component. If this component is not fixed, it can rattle around and cause further damage to other parts of your furnace.
Running a malfunctioning furnace is also unsafe. From electrical problems to overheating, there are several risks associated with loud furnace noises. Make sure you keep your home and family protected by scheduling furnace noise diagnosis and repair services right away.
