If you grew up with a furnace, you probably like the clicking sound of it turning on, the rumble of its running, and the rush of warm air through the vents. These are all sounds of cooler weather, and they can be very comforting. However, if you live in a home with a furnace now, when you start to hear different sounds, you suddenly have to wonder if something is wrong. Your furnace can become a source of stress rather than comfort.

When your furnace stops speaking the language of comfort, what does it mean? Are the odd noises you’re hearing serious? At James Brown Air Conditioning and Heating, we spend a lot of time listening to clients try to make the same noises as their furnaces, and we have experience with what they mean. In today’s blog, we’re going to share a bit of our expertise!

What Does It Mean When My Furnace Is…

  • Rumbling

    • If you’re hearing more than the normal rumbling, it can mean several different things. The burners might be dirty or the pilot light might need adjustments. These are small issues that can become more serious if they aren’t addressed by normal preventative maintenance.
  • Squealing

    • Many people find this sound alarming, and we understand. You never want to hear squealing from a furnace. If you do, your furnace may have an air leak or a loose belt. You will want to contact us immediately to for service so your furnace doesn’t get more damaged.
  • Clicking

    • You should hear a single click when your furnace turns on. That is the sound of the ignition. However, if you hear additional clicking, you will want us to come and check out your ignition and heat exchanger to make sure your furnace is working correctly.

  • Swooshing

    • If you get a swooshing noise followed by a bang or click coming from your furnace, there may be a leak in the gas valves. You want to shut off your gas line to ensure that gas doesn’t get built up and then give us a call immediately.
  • Booming

    • Depending on the type of boom, it may or may not be serious. A quiet boom is common to hear when the warm air storage box on the top of the furnace expands. You don’t need to worry about that. However, if you hear noisy, frequent booms, you should contact us right away. These booms are caused by dirty burners or delayed ignition, which causes small amounts of gas to build up and explode.
  • Screeching

    • Like squealing, this is an unnerving sound to hear. It usually means that your furnace has worn out bearings, issues with its blower motor, or a faulty belt. You’ll want to get in touch with us right away.
