Weird Furnace Noises and What They Mean

  • Banging - If the gas burners in your furnace get dirty, it may result in the ignition being delayed. When the excess of gas that builds up in the ignition chamber ignites, there will be a small explosion, creating the startling bangs that you hear coming from your heating system in Minnesota.
  • Humming - A low humming noise coming from your furnace while it's operational is nothing to worry about. But if you notice that humming gets louder over time, it can be indicative of internal issues. Problems with fans and capacitors most frequently cause humming noises to emanate from heating systems in Minnesota homes.
  • Rumbling - A droning rumble coming from your furnace can indicate a variety of problems. These rumbling noises usually occur when internal components become loose or otherwise faulty, causing them to shake excessively while in operation. Burners, heat exchangers and blower motors are just a few of the parts that can cause these rumbling noises in heating systems in the Twin Cities.
  • Scraping - Metal scraping sounds coming from your furnace are likely to give you a migraine in minutes. The most common culprit of this awful noise is a blower wheel that has become loose. Damaged ball bearings are another source of scraping noises in heating systems.
  • Squealing - One particularly obnoxious noise that furnaces can make is high-pitched squealing. A few different problems can cause these squeals. The underlying issue may be a damaged blower belt, a malfunctioning blower motor or a shaft bearing that needs to be oiled.
