4 Reasons Your Furnace in Sharpsburg, MD, is Making Weird Noises

November 19, 2020

When you hear strange sounds while your furnace in Sharpsburg, MD, is running, one of its components needs maintenance or repair. In this guide, you’ll discover the most common reasons weird noises emit from a typical furnace.

Blower Motor Sounds

During a heating cycle, you may detect screeching sounds. These noises are commonly caused by defective bearings on a blower motor or the motor’s own hardware. You’ll no longer hear screeching sounds after a service technician lubricates the motor.

Damaged Blower Belt

A damaged or loose blower belt causes squealing sounds. Squealing can also happen if the shaft bearings are dry because they lack lubrication.

You can protect a blower belt by scheduling tuneups. Following bi-annual appointments, the moving parts will less likely dry out before and throughout the winter.

Blower Wheel

The metal surfaces on a loose blower wheel can make clanking sounds. You’ll hear this sound because the metals surfaces of the blower wheel are constantly rubbing against the housing.

Immediately after you notice a grinding sound, turn off the furnace and seek professional maintenance services. Depending on the fan’s condition, a service technician will either replace or repair it.

Grimy Burners

Because burners produce heat, the most dangerous burner-related sounds are quite noticeable. If your furnace’s burners are dirty, you’ll clearly hear a loud boom immediately after it begins a heating cycle.

While dirt is on the burners, you’ll experience a delayed ignition. This timing issue helps gas build up within a furnace. When a furnace can no longer handle the pressure, an explosion can happen during the ignition process. A tuneup prevents this because a service technician always inspects and cleans all dirty burners during the maintenance routine.

If your furnace makes weird noises, call Hagerstown Heating & Cooling to set up an appointment for furnace maintenance. We also offer a great duct cleaning service that can help you get the most out of your heating system.
