Why Is My Furnace Loud?

A furnace in operation is by no means silent, for sure. However, common sounds of operation are little more than background noise that nearly any homeowner has long since grown accustomed to. So what’s that clank you’ve been noticing recently when your furnace kicks on? Or the whistle that has developed over the last few weeks that is quickly becoming unbearable?

Odd sounds are one of the surest indicators of a serious need for repair, and most sounds are a clear sign of a specific issue. Why is this important? Because understanding how to read the signs, and how to identify the odd sounds coming from your furnace, can tell you when it’s time to call on the professionals and what needs to be done.

Causes of a Loud Furnace

A furnace in need of repair can make a number of sounds, most of which indicate a specific issue or series of issues:

• Clanking or banging. A loud banging when your furnace is in operation can mean a component in your system has become damaged, or has come loose. This is a particularly urgent problem, as loose components can cause further damage to your system, and can eventually result in a need for replacement if left unaddressed.

• Whistling or whining. A high pitched whistle or whine often tells our experts that there is an issue with the ductwork. Gaps in your ducts can cause a whistle that is both obnoxious, and detrimental to the efficiency of your unit. A clogged or dirty filter can also cause whistling, as your furnace begins to pull air from any gap or hole it can find. Check your filter and ensure you’ve changed it recently before calling in the specialists for a repair!

• Screeching. A particularly maddening sound to hear from your heating system, a screech tells us that an issue has most likely occurred with the blower motor. If it has become damaged, loose, or if it simply lacks lubrication and is generating excess friction, a screech will ensue.
