Why Does My Furnace Sound Like Running Water?

Lots of heating systems can produce annoying noises, like gurgling or knocking sounds coming from a boiler or radiator. Old furnaces rarely made running water or gurgling noises because there was no condensation or liquid involved.

Today, newer and high-efficiency furnaces do produce condensation. This means that under certain circumstances, your furnace will sound like there’s running water somewhere.

Liquid sounds coming from the furnace do not necessarily mean there’s a major problem, but there could be massive and expensive damage if you don’t get it checked out by a heating technician as soon as possible.

What to Do About a Furnace with Running Water Sounds

Don’t just put up with strange noises as a fact of life. Your furnace should operate relatively quietly if nothing is wrong. For your quality of life and to make sure you don’t have a major heating problem beginning, ask a heating expert to troubleshoot the water sound.

First, though, there are some things you can do to troubleshoot the cause of the noise:

  • Look for a leak or spilled water. This would be a puddle around the condensate pump, which can occur if the drain pan has perhaps been knocked askew and is dumping water onto the ground.
  • If possible, try to unclog the drain pipe and re-position the drain pan. This will ensure the liquid can properly flow (usually to a white pipe).
  • Identify where the running water noise is coming from. For example, running water that sounds like it’s coming from the walls can indicate a condensation problem in your ducts or other infrastructure. Get a professional furnace inspection soon to prevent moisture damage and detect HVAC problems.
  • Ask yourself: Is there anything else that could be making the sound? If you cannot determine what area or which component of the furnace the noise is coming from, try to find out if the noise is coming from somewhere else. For instance, do you have baseboard heating or a hot water tank that might be acting up?

Furnace Repairs for Running Water or Other Strange Noises

We understand that you don’t want to make a service appointment if you don’t need to. As you troubleshoot, remember that a noisy furnace can turn into a bigger issue than it seems at first. The furnace might be working fine otherwise, but the condensation problem or leak could be slowly ruining parts and leading up to a major breakdown.

If you find a puddle around the condensate drain pan and you can get that straightened out on your own, everything might be all settled. If you find rust or damaged parts, or the noise issues linger, go ahead and make a routine maintenance inspection for your furnace to be on the safe side.
