The furnace in your Hurricane, WV, home should operate fairly quietly throughout the winter. Other than a continuous gentle hum and perhaps some temporary popping sounds, the system should make no noise at all. Here are a few possible explanations for why your furnace has suddenly become loud:
Screeching Furnace
The usual cause for this piercing and annoying noise is a worn-out belt. The belt’s purpose is to connect the motor to its blower, allowing your furnace to blow out warm air. Hence, if your heating system screeches and refuses to push out air, an HVAC service technician will likely need to replace its belt.
Rattling Furnace
If pebbles, twigs, dirt or other debris find their way into your furnace, they may begin rattling around in the system’s interior. Alternatively, you may hear rattling if your furnace’s panel door comes loose. In the most extreme scenario, rattling noises may indicate that there’s a crack in your furnace’s heat exchanger.
A standard tuneup will probably be enough to clean debris out of your system and tighten the screws that hold its panel door in place. If the source of noise lies in your heat exchanger, you’ll need more significant furnace repairs.
Banging Furnace
As mentioned, your furnace may sometimes make loud popping sounds. Since thermal expansion generates these noises, they shouldn’t persist for very long.
If louder banging noises continue, the problem could be your furnace’s burners or heat exchangers. If your furnace’s burners become dirty, they can create ignition issues, which make a loud bang. If the heat exchanger cracks, heat expansion can cause the noise.
