During the cold months, your furnace should run smoothly and quietly. If you observe unusual noises, there might be problems with your HVAC system that risk compromising your comfort, property, and safety. Here are a handful of abnormal sounds and what they mean. 

5 Furnace Noises That Suggest Trouble 

1. Booming

Booming sounds may be the result of soiled burners or gas buildup, which cause your furnace to misfire. The booms you hear are actually miniature explosions that may crack your unit or cause fire hazards. 

2. Screeching 

When your furnace screeches, the motor or blower belt is usually the culprit. These parts may have become dislodged, causing them to rub up against the walls of your furnace, which creates the noise. Schedule repairs ASAP to keep the damage to a minimum.

3. Clicking

Clicking typically means the flame sensor within your furnace is no longer functional. You’ll hear these noises as your unit attempts and fails to ignite. Prevent possible gas leaks and other issues by booking an inspection appointment. 

4. Rumbling

If you hear rumbling from your furnace, oil may continue to burn even after the unit shuts off. This makes carbon monoxide more likely to infiltrate your home, and the consequences can be fatal. Contact an HVAC repair team immediately to address it.

5. Rattling

Rattling points to trouble with the heat exchanger, ductwork, or panels. It may also indicate loose fan blades or debris buildup. Hire a heating contractor to clean out your unit and replace any faulty parts.
