Let’s talk about some unusual noises you could hear from your equipment, especially your furnace, such as squealing noises, what can cause it, and how to fix it.
When My Furnace Gives a Squealing Sound, What Does it Mean?
It could result from a loose belt, a furnace heil blower motor, a dry bearing on a motor, or possibly a combustion blower motor. If the noise is consistent and gets louder, it’s nice to get a diagnosis.
Generally, in terms of squealing, it’s often caused by dry bearings.
Can the Bearings or the Whole Unit be replaced?
Usually, the blower motors are in the heat passage, and those will dry out over a period, and they’re seal bearings. They’ve got an oil cage, and after a period, they’re gone due to longtime furnace usage (ten years or more); the heat is taking its toll, and it starts to dry out.
The best thing to do is get it out and replaced when it’s convenient, rather than on a cold January night.
