Is Your Furnace Making Weird Noises?

Furnaces can run into a wide range of issues during their many years of warming your home. After a while, you may notice some odd sounds coming from your systems. From rattling to high-pitched sounds to humming and more, it’s vital to know what these sounds mean and what needs to be done to fix them.

In this blog post, we’ll look at some of the most common sounds you may hear from your furnace, what causes these sounds, and how a professional HVAC technician can resolve these issues for you.

Types of Noises a Furnace May Make

Furnace sounds can be nerve-racking, but they don’t have to be. If you understand what’s causing the noise, it’s easier to know what your system needs. Some of the most common furnace sounds include:

Rattling sounds

A rattling sound can make your furnace sound like something metallic is rolling around inside the system. You may hear these noises when the system is running for any amount of time.

Ratting sounds coming from a furnace could be a sign of loose parts within the system. When small metal parts such as screws or bolts fall out of place, they may be shifted around within the furnace as it’s running. This can cause a rattling noise that can be heard throughout the home.

Rattling sounds could also be a result of a cracked heat exchanger. This is the part of the system that heats your air. The heat exchanger is made of metal and is constantly moving warm and cool air through the system. This temperature change can damage the metal, cracking it open and leading to a rattling noise.

High-pitched noises

High-pitched squeals or shrill noises can be super irritating, especially when they come from your furnace. These noises can come from your system for a short time as the system warms up or any time the furnace is on.

These noises can be caused by worn-out blower motor bearings that have taken on damage after years of use. Replacing these bearings can be a breeze with the help of an HVAC technician.

High-pitched noises coming from your furnace can also be caused by low airflow through the system. Dirty air filters, damaged air ducts, and closed air vents can all lead to these sounds.

Humming or buzzing sounds

Buzzing noises and humming from your furnace can be worrisome, but these issues can often be fixed easily with the help of a professional. These issues can arise as the furnace starts up, or they can last as long as the system is running.

Buzzing and humming sounds are common for a furnace, but when they become loud, it’s typically related to the electrical system. A faulty transformer, a failing blower motor, or a bad inducer motor are all common culprits.
