Weird Sounds You Don't Want to Hear Coming From Your Furnace

Weird Sounds You Don't Want to Hear Coming From Your Furnace

Are you hearing weird sounds emanating from your furnace? Air whooshing through the registers, the gentle hum of the furnace blower, the air handler powering down - these are all normal noises for a furnace to make. But if you hear any other noise coming from the furnace, you may need to take action. During the winter months, in particular, you can’t afford to have your furnace fall into disrepair.

The weird sounds that tend to signal a larger problem include:

  1. A rumbling noise, which can indicate that there’s dirt buildup on the gas burners. If your furnace is old and employs a pilot light, that component may need to be adjusted.
  2. A squealing sound, which can mean that a belt on the blower has come loose or even slipped off. Older furnaces that aren’t self-lubricated may need to have their bearings serviced.
  3. A vibrating sound, which often means there’s a problem with the blower motor.
  4. A banging noise coming from the ducts, which may not necessarily be a cause for concern. Ducts expand and contract as they adjust to warm air flowing through them, and when the air stops, cooler air settles in. However, if you hear weird sounds continuously, the problem likely stems from elsewhere.
  5. A rattling sound, which can emanate from a loose component like the service panels or terminals, a damaged heat exchanger or a leaky combustion chamber.

If you hear your furnace making weird sounds, it’s best to call in a professional to assess the situation. Gas-powered furnaces are highly complex and dangerous when left in the hands of a novice. Because of the risks of a natural gas leak and the hazards that carbon monoxide poses to your family, call an HVAC contractor when your furnace acts up.

Frugal homeowners may not want to pick up the phone to call a professional if they’re not entirely sure that the noise they’re hearing represents a legitimate problem. However, reputable HVAC contractors will have a conversation with you to determine the issue at hand and walk you through a few troubleshooting steps before coming to your residence. It’s always safer to get in contact with a pro if you’re unsure. And if the problem can be solved on the phone, you might not have to spend money.
