It’s late at night in McMurray, PA, and a strange rattle echoes through your home. Is your furnace trying to tell you that it needs a repair? Before panic sets in, it’s worth learning what those mysterious sounds mean.
When Clanks and Bangs Cry Out for Help
If your furnace has started performing its own drum solo, it might be time to pay attention. Loud banging or clanging often indicates expanding or contracting metal ducts or loose internal components.
According to the U.S. Department of Energy, nearly 30% of furnace energy loss comes from poor maintenance and ignored warning signs. A quick inspection by our experts can help you catch issues before they turn into full-blown breakdowns.
Whistles, Hums and Rattles Aren’t Good
High-pitched whistles may mean a clogged air filter or an air leak in your ductwork, while a low hum could signal an electrical issue. Rattling noises often point to unsecured panels or motor issues.
Each sound tells its own story, and ignoring them can be like turning down the radio to avoid the check-engine light. The fix might be simpler and cheaper than you think if caught early.
Possible Furnace Noises and What They Mean
Before calling in the pros, listen closely to identify the type of sound. Here are six furnace sounds you might hear:
- Banging: Ignition delay or dirty burners.
- Whistling: Airflow restriction from a clogged filter.
- Rattling: Loose screws or unsecured panels.
- Squealing: Worn or slipping blower belt.
- Clicking: Failing ignition system or relay.
- Humming: Electrical issue or failing motor.
