Don’t Ignore That Annoying Heating Noise

You’re familiar with the sounds your home makes. You know the sound your front door makes when it opens, the creak of the floorboard in your entryway, and if you listen closely, we’re sure that you’re familiar with the sounds your heater makes too. Your heater isn’t a completely silent system. If you’re cold at home, we’re sure that you hear the click your heater makes when it turns on and feel relief. Although there are some expected noises that can come from your heater, this system shouldn’t make too much noise. 

If you’re having trouble finding the line between “just right” and “too much,” then you’ve found the right blog. We specialize in heating repair in Niwot, CO so we’re familiar with the signs noises you should listen out for. We’ll get into a few below. 

Noises You Don’t Want to Hear from Your Heater

Here are a few noises that you never want to hear from your heater. If you do notice these sounds, make sure you alert a professional heating technician to them as soon as possible. 


Have you noticed that there’s now a loud banging sound that occurs when you run your heater? This might happen when your furnace kicks on. If it does, then it’s likely a problem stemming from the ignition. When your furnace receives the signal from your thermostat to begin heating, the gas valve opens, and then the pilot light should ignite the gas right away. If there’s a problem with the pilot light or the ignition system, you might hear a loud bang.


Your furnace shouldn’t whistle. If it does, then you’re literally hearing your furnace system struggling to circulate air. You can’t think of this as your furnace’s equivalent of a person coughing, sneezing, or wheezing. Your equivalent of saying “bless you” or offering a tissue or glass of water is contacting a professional to work on your heater.


Does your home’s furnace rumble as if lightning is on its way? When your furnace powers on, you should hear a subtle whoosh that’s barely discernible if you’re not listening for it. You might even notice a roaring sound. If this roaring sound transitions into a rumbling sound, then you’re having a combustion problem. This often denotes a budding issue with carbon monoxide. This can become potentially dangerous and you need urgent repair.


Screeching, squealing, or scraping, then it’s highly likely that a piece of metal is scraping a different part of your system. Loose parts within a furnace system typically still try to function and they can cause problems when they do. One of our technicians can find where things have gone wrong and work to fix it. 


Vibrating or loud humming are both sounds that point to electrical problems. It could also be a problem with a loose screw or loose part that’s moving while your furnace system operates. Loud vibrating is a problem you should get in touch with a professional as soon as possible.
