Strange Furnace Noises & What They Mean

It’s customary to hear sound when many appliances or home comfort systems are running. Some homeowners may have difficulty, though, discerning between what is normal and the types of noises that cause concern. How can you tell the difference between usual furnace sounds and what may be warning signs or out of the ordinary furnace noises? 

A furnace that is operating as it should typically has a low hum or a similar soft sound. Any furnace noises that sound like loud clicking, banging, clunking or popping, are not the status quo and should be checked by a professional HVAC technician. If a broken or worn component is discovered, Masters Heating & Cooling will complete a furnace repair efficiently to keep your home warm for you and your family.

Furnace Noises:  What They Are & What They Mean

• If you hear rattling, it could be just a loose panel or access door. If after you check the doors and panels, you still hear rattling, it could be a loose part inside the furnace. Call Masters for a complete inspection and furnace repair. 
• Metal against metal or scraping sounds could mean there’s a problem with the blower wheel. It could be loose or even need to be replaced. 
• Popping sounds can occur with the normal expanding and contracting of the ductwork. Frequent or exceptionally loud banging should never be diminished. Call Masters to rule out any serious issues within your furnace.
• Screeching may mean the bearings in the blower motor need lubricated. This may also be a sign that a belt needs to be replaced. 

If you’re unsure about the sounds your furnace is making, it’s never wrong to be cautious and call an experienced and trusted HVAC company like Masters Heating & Cooling to fully inspect, clean or repair your furnace.
