Why Is My Boiler Making Strange Sounds?


If your boiler is going bump in the night, you could have a severe problem requiring professional intervention. But before you call, you can do some detective work on your own to get to the bottom of things. Here’s a step-by-step way to kick off your boiler noises troubleshooting in Staten Island.


Find the Origin of the Noise

A significant identifier of any given boiler problem is where the sound originates within the system. You can’t correctly do any boiler noises troubleshooting in Staten Island unless you know where the noise is coming from.


The next time you notice the noise, get up close and personal — do you hear something coming from the pipes? Does it sound like a gentle creaking or a loud bang? Record your findings; they’ll be handy later.


Consider What the Cause Could Be Based on the Noise

There will always be a reason your boiler is making unusual noises. But depending on the sound, many things could be at play with varying degrees of complexity to fix.

For example, if you’re hearing a lot of loud banging, it could be a few issues, like debris buildup or a faulty thermostat. Either would need the help of a professional. Still, it’s good to recognize and handle the issue before the problem spirals out of control.


Other sounds, like vibrating, could be as simple as some loose brackets. Fortunately, this is something the average homeowner can diagnose and adjust themselves. That said, if tightening the brackets doesn’t fix the issue, you’ll still need someone to come out and look at it.


Another typical sound — whistling — stems from a specific issue called kettling. The noise surfaces when there’s a lot of limescale on your boiler’s heat exchanger. 

A whole chemical reaction happens between the calcium deposits in the water, but the short version is that kettling isn’t great for your boiler; call a professional soon to avoid it breaking down completely.
