Common Furnace Noises Explained: Separating Fact from Fiction

One of the most persistent myths in home heating is that any unusual noise coming from your furnace automatically signals an expensive repair bill. At J. E. Shekell, we’re here to debunk this common misconception and provide some peace of mind to homeowners across Indiana and Kentucky.

Understanding Normal vs. Problematic Sounds

Not all furnace sounds indicate trouble. Here’s what you should know:

• Light humming – Usually normal operational noise
• Clicking when starting/stopping – Typically just the system cycling
• Slight whooshing – Often just air moving through ducts
• Expansion/contraction sounds – Normal with temperature changes

When to Actually Worry

However, some sounds do warrant professional attention:

• Loud banging or booming
• Persistent squealing
• Metal-on-metal scraping
• Continuous rattling

The Cost-Saving Truth

Many noises can be resolved with simple maintenance rather than major repairs. Regular furnace service often prevents these issues altogether, saving you money in the long run. In fact, most concerning sounds can be addressed during routine maintenance visits.

Take Action

If you’re hearing unusual sounds from your heating system in Evansville, Henderson, Vincennes, Newburgh, or Princeton areas, don’t automatically assume the worst. Having a professional diagnose the issue early can prevent minor concerns from becoming major expenses.

Remember: The best way to avoid serious furnace issues is through regular maintenance and prompt attention to any changes in your system’s operation.
