While your furnace works hard to keep your home warm during the fall and winter, it’s only natural for it to make noise. However, sometimes, there might be an odd noise that makes you uncomfortable. It’s important to identify these sounds and know what they mean.
A banging noise can signify that your furnace experienced a minor gas explosion. That occurs when it takes too long for your furnace to ignite. The problem might be due to improper gas pressure or a clog. A professional should inspect your furnace to fix the problem.
Scraping sounds emanating from your furnace means that the ball bearings may be worn out. It might also mean that the blower wheel may have loosened. In either situation, you should turn off your heat and contact an HVAC specialist to come over and make repairs.
A clicking noise in your furnace usually means there’s an ignition problem. The clicking sound is due to the furnace automatically trying to ignite. However, it might also mean there’s a loose bearing, broken flame sensor, or dirty burner.
Squealing or Whistling Noise
The blower is usually the culprit when you hear a squealing noise coming from your furnace. If the blower is unable to work, it’s probably due to the motor being worn out due to age or overheating. If it’s due to age, you will need a replacement. If it’s due to overheating, it might simply need cleaning.
A whistling noise means there’s insufficient airflow inside the furnace. You may need the vents cleared, the air filter replaced, or ducts repaired or cleaned.
A buzzing noise coming from your furnace signifies that there is an electrical problem that requires an expert’s attention. It might be a faulty inducer motor, bad transformer, old or dry blower motor, or bad motor capacitor. Any of these problems involves the electrical parts of your furnace, which means a professional is needed to make repairs.
