Are Those Furnace Noises Normal?

Furnaces often make noises (most especially the older models). Normal sounds include the minor pops that emanate from the ducts as well as the humming of the furnace which is being heard as the blower runs. If the noises you are hearing are so loud to the extent that they can keep you awake at night, then they are not normal and you should seek for a repair or professional maintenance.

If these noises are not paid attention to, they could lead to serious problems in the form of costly repairs or replacement as time goes on. Highlighted below are four noises you should be on the lookout for in your HVAC system.

Squealing
This type of noise occurs when the belt which connects the motor and fan together slipped or needs replacement. If the belt is not replaced, it can break thereby causing the blower to stop turning.

Repeated Clicking
Clicking noises are normal noises when the furnace is being turned on and off. When the noise persists (when it keeps emanating from the control panel or outside compressor), then it is not normal. It could be due to a fault in the relay or the electrical control is casing a break down in the relay.

Grinding
If a grinding noise is heard from the blower, shut off the furnace and put a call through to a technician. It may be that the motor’s bearings need to be replaced. The belt may need to be realigned or maybe it is worn out and should be replaced.

Rattling
A furnace that makes a rattling noise while working could be due to loose cover panels. In this case, tighten the cover panels. If the noise persists, then get in touch with a qualified technician to check it out. It may be that the blower is out of alignment or a malfunctioning in the motor.

    Thank you for writing this article. I was able to find a lot of useful information from this article. From now, I will be alerted if I hear a sound from the furnace. After all, safety should be the prime priority.
