If your furnace generates odd and loud noises, it’s critical to identify the noise source to resolve the problem. Noise in the device might suggest a far more serious problem or perhaps damage. Several elements might cause sounds to arise, each making a unique noise.

It would help if you did not disregard noises from the furnace. However, because the noises are normally so loud, they would be difficult to ignore even if you tried!

Causes of Loud Noise From Your Furnace

When you have a furnace creating loud rumbling noises, the spectrum of potential problems extends from small to dangerous and needs immediate attention. The rumbling is usually related to particular heating system difficulties, but additional failures might cause rumbling.

  • The Dirty Burners

The most typical cause of this noise is clogged burners. During normal furnace operation, soot accumulates on the burners and should be cleaned regularly. This is done as part of your annual furnace tune-up by KS Services. Soot can clog airflow if the burners are not cleaned regularly. In this instance, the burners do not receive sufficient airflow for combustion, resulting in a furnace that makes a loud, rumbling noise. The rumbling happens at the start of a heating cycle and during furnace operation. 

This condition is usually avoided by doing annual furnace maintenance. If your furnace burners are coated in soot, contact an HVAC specialist to clean them.

  • Problem With the Pilot Light

If your furnace is more than 15 years old, it most likely needs a pilot light to start the combustion process. When this element is not correctly transmitted or covered in soot, it can cause a furnace to generate rumbling noises. You can hear the sound while the furnace runs and even after a heating cycle has finished. You can hear the sound while the furnace runs and even after a heating cycle has finished.

  • Motor for Dirty Draft Inducer

The draught inducer in a furnace is located near the heat exchanger. It directs combustion gases into the flue pipe, securely expelled from the house, avoiding exposure or explosion inside the heat exchanger. It also delivers oxygen to the burners to help them function more efficiently. When this component is dusty or loose, it might cause a rumbling noise when the system starts up for a heating cycle.

  • Loose Panels

The furnace’s outside access panels might become unfastened and cause sounds while the system functions. Although rumbling can occur if the screws are only slightly loosened, they often smash around. Examine the furnace’s exterior to confirm that all metal panels are correctly fitted and fastened. Screws should be tightened as needed.

  • Heat Exchanger Cracked

A fractured heat exchanger is possibly the most significant problem a furnace may have, necessitating emergency servicing with no usage until repair or replacement is finished. A breach in the heating tune-up Lancaster, OH permits carbon monoxide to escape and mix with the air supply rather than venting securely outside, posing the risk of fatal carbon monoxide poisoning inside.

The sound generated is often a clink or rattling noise. However, you can hear a low-pitched rumbling in some systems. If none of the other factors listed above are present, a damaged heat exchanger might be the noise source. Please turn off your furnace, disconnect its gas feed, and contact your HVAC in Zanesville Ohio.

Never ignore any of these furnace noises! As soon as you detect them, contact a skilled heater repair Zanesville. Remember to schedule yearly furnace maintenance at the start of each heating season to keep your furnace safe and efficient all year.
