6 Furnace Noises You Should Never Ignore & What They Mean

Posted On: January 11, 2018

It’s the start of a new year, and whether you’re excited for the year’s prospects or just taking it one day at a time, some things never change. As HVAC professionals, of course, our focus is on your heating systems for the duration of the cold winter months. Proper HVAC maintenance and upkeep is just as important this year as it was last year—and it will continue to be important for the foreseeable future!

If your home is heated by a furnace, then you probably know how scary it can be to think something is wrong with it. Odd clunks in the night, strange rattling sounds as the heat kicks on, so on and so forth. While some sounds are just the furnace doing what furnaces do, there are a few noises that you should be sure you don’t dismiss, whether or not your furnace seems to be in working order.

Keep an Ear & Eye Out for These Furnace Noises

  • Grinding sounds. The sound of metal grinding against metal can be very alarming, and honestly in the case of your furnace it should be. Grinding sounds are typically an indication that a mart has come loose or has been heavily damaged, which can do considerable harm to the system if left be.
  • Vibrations or rattling. A slight vibration accompanied by rattling is often a bearing or blower motor component that has come loose. Similarly to above you need this to be remedied as soon as possible to avoid further trouble.
  • Squeals or squeaking. Loud squeaks, squeals, and screeching can be traced to belts in your system. These are usually belts in the blower assembly and the sound is created by cracked, old, or otherwise worn out belts. A simple furnace repair is often enough here, but it needs to be handled soon to avoid loss of heating power.
  • Persistent clicking. Most of us are familiar with the short burst of clicking that can happen when a furnace cycles off and is “cooling down.” But if this sounds continues to happen all throughout the furnace’s operation, or happens in a furnace that fails to start completely, the igniter is likely at fault.
  • Banging or rumbling. Loud bangs or booms in a gas furnace system will often mean the fuel is burning in bursts or the ignition is having trouble. The sound is a buildup of gas igniting all at once, and this can be as dangerous as it sounds. If you hear booms or rumbling we would recommend shutting the furnace down and calling an expert as soon as possible.
  • Humming or buzzing. Humming or buzzing will usually be heard near electrical components in a furnace system, whether the furnace is gas or electric. The sound tends to mean connection issues or electrical component failure, which can be a fairly serious issue.
