What’s Making My Furnace So Noisy in Raceland, LA?

A loud furnace is frustrating and often a cause for alarm. If your furnace in Raceland, LA, is making unusual noises, you shouldn’t just ignore it. Here are some possible causes for why your furnace is so noisy:

Dirty Air Filter Due to a Clog

A dirty air filter that has a clog restricts airflow, which makes the furnace have to work harder. This might cause a whistling or whooshing sound as air struggles to pass through the air filter.

Not only can a dirty air filter make the furnace noisy, but it can also negatively affect your indoor air quality. Replace your filter every one to three months to keep your furnace running quietly and reduce pollutants in the air.

Parts Inside the Furnace Are Loose

Screws, panels or other parts inside the furnace can become loose. This usually occurs due to normal vibrations that the furnace makes during operation. If something is loose inside the furnace, you might hear rattling or banging sounds.

There’s an Issue With the Blower Motor

The blower motor turns the fan that moves air through the furnace. This air flows over the heat exchanger and into your home via the ductwork. If this motor gets out of balance, dirty or faulty, it can make humming, grinding or screeching noises.

Ductwork Makes Noise During Expansion

You might think the noise you hear is coming from the furnace when it’s not. When your furnace starts and stops, the metal ductwork in your home can expand and contract due to temperature changes. he contracting and expanding ductwork can make popping sounds.

Ignition Problems

If you hear loud booming or banging when your gas furnace starts, that could mean there’s an ignition problem. This happens when gas builds up before igniting, causing a mini explosion. This is potentially a fire hazard, so address the issue as soon as possible.
