The Right HVAC Unit for Your Home

Is Your Furnace Making Strange Sounds? Find Out What They Mean

by Jamie Shaw

With the temperatures steadily decreasing, your furnace will be instrumental in keeping your house warm during the cold season. However, if your heating appliance begins to make weird sounds, it can cause a noisy and unbearable operation. Since these sounds indicate various problems, hiring an HVAC expert for a diagnosis call-out is crucial. They will determine the cause of the malfunction and fix it. The following loud furnace sounds will help you understand what they mean.

Scraping Sounds

If your heating unit produces a sound that resembles a train scraping away on tracks, your blower wheel could be scraping against the motor. Moreover, the scraping sounds could be caused by a broken motor mount, resulting in the blower wheel tumbling over your unit's surface. Therefore, if you hear your heating appliance making scraping noises, contact a furnace repair expert to replace the motor mount and fix the dislodged blower wheel. They will also lubricate the ball bearings to avoid overheating from grinding metal surfaces.

Wheezing Sounds

Air filters remove dust and debris for a clean and warm air supply. Over time, the filters clog with debris accumulation that restricts airflow. Since the debris build-up constricts the air passages, your heating unit will make wheezing sounds as it strains to draw in air. You must schedule regular furnace tune-ups for the technician to clean or replace your air filters, depending on whether they are reusable or disposable.

Booming Sounds

The gas burner could be defective if your heating appliance produces a loud booming sound. This is due to dirt, dust and other organic matter contamination that causes a gas build-up before the furnace starts. As a result, your heating unit will produce a booming sound when the flame ignites and can crack the heat exchangers, leaking carbon monoxide. To avert the danger of gas poisoning from a leak, you should hire professional HVAC services to routinely clean your gas burner to prevent build-up that might block your ignition.

Squealing Sounds

A high-pitched squeal from your heating unit will indicate that the blower motor compartment is malfunctioning. If the bearings are worn out from continuous friction, you will hear a squealing noise from the blower motor's operation. Moreover, your furnace will shriek if the fan belt is loose or misaligned. Therefore, you should engage a furnace technician to replace the motor bearings and tighten the belt to the right tension.

If your furnace makes weird noises, it could indicate an underlying issue. Therefore, you should hire an HVAC repair expert to examine your heating unit for signs of deterioration or aging. They will replace the worn-out parts for optimized function.
