Need a Furnace Repair? 4 Sounds That Scream Yes!

Do you still use a furnace to warm your Land O’ Lakes, FL, home rather than a heat pump? While some furnace sounds are normal, most signal serious trouble. Schedule a furnace repair if your system produces these noises:

Banging Blower Wheel

If you hear loud bangs or clanging noises from your furnace, it could be a sign of trouble with the blower wheel. The blower wheel is crucial for circulating warm air throughout your home. Over time, wear and tear can lead to an imbalance or damage in the blower wheel, causing it to hit the housing.

Screeching Blower Belt on the Brink

A high-pitched screeching or squealing sound is often a telltale sign of a failing blower belt. The blower belt is responsible for connecting the motor to the blower wheel. When it wears out or becomes misaligned, it screeches. Ignoring this noise can result in a complete breakdown of the blower system, so change the belt immediately.

Clicking Ignition System

Clicking or popping sounds during the startup phase indicate issues with the ignition system. This system initiates the combustion process that produces heat. A malfunctioning ignition system can lead to delayed ignition or repeated attempts to ignite, causing clicking noises. Ignoring this problem could result in a total furnace failure.

Rumbling Heat Exchanger

A deep rumbling or roaring sound from your furnace might indicate trouble within the heat exchanger. The heat exchanger is a vital component that transfers heat from the combustion process to the air. Over time, cracks or damage to the heat exchanger can cause these ominous sounds. A compromised heat exchanger poses serious risks, including carbon monoxide leaks. If you hear these noises, shut down your furnace and schedule an inspection.

While some furnace problems are easy and inexpensive to repair, others warrant a complete system replacement. Call Dymond Heating & Cooling when you need assistance troubleshooting furnace sounds and finding the best repair solution.
