Why You Hear a Loud Bang

If you hear a loud bang or “boom” when your furnace ignites, it is a serious warning sign. This sound often indicates a delayed ignition. Gas may be building up before lighting, causing a mini-explosion inside the unit. This is dangerous and compromises safety. Call for expert heating repair in Littleton right away to diagnose and resolve this explosive issue quickly.

High-Pitched Squeals

A piercing squealing sound is usually mechanical. This noise is typically caused by a failing belt or a motor bearing that is wearing out. As these components degrade, friction increases, leading to this sharp noise. If you hear a screech, the issue could escalate fast, potentially causing the entire fan motor to seize. Schedule an appointment before this small fix becomes a costly replacement.

Repetitive Clanking, Thumping, or Rattling

When your heating unit sounds like a washing machine full of metal, it often means something is loose. Check the blower wheel for obstructions or look for loose panels on the exterior. More seriously, it could be a broken component hitting the fan blades or a motor mount coming apart. It is critical to address clanking immediately to prevent further damage to internal parts.

Intermittent Clicking Sounds

Constant, rapid clicking that prevents the burner from lighting is a common problem. It typically indicates an issue with the ignition system or gas valve. The system may be trying to light the flame but failing and entering a safety lockout. While less immediately explosive than a boom, this means your home is not heating efficiently. Reliable Priority Home Services technicians can resolve this issue fast.
