Furnaces are not generally noisy, especially modern furnaces that are designed for noise reduction. A properly working furnace should  not make any noise. A furnace that is making some unusual noises might need some repairs. The type of sound you're hearing can actually help determine the issue with the system.

We will walk through some of the most common sounds that a furnace makes and detail what they signify. If you hear any of these sounds, then contact us for any heater service in Perth. We will inspect the furnace and fix the issue.

1. Scraping Noise

A scraping noise indicates that there's some fault in the blower wheel of the furnace. This noise will sound like metal parts rubbing against each other. If you hear such noise, you'll have to call a technician as soon as possible, as this sound can indicate issues related to other wear-and-tear in your system.

Your furnace can make these noises for various reasons. The wheel might have become loose and is making the noise by hitting against the blower casing. A broken blower wheel can also be the primary cause of this distinct noise.

2. Screeching Noise

Generally, a screeching noise can indicate problems related to the motor bearing. Adding some lubricant by a professional technician can resolve the issue with the motor bearing. Another common cause of this sound could be a bad belt. You need to call a technician to replace the belt as soon as possible, or else the blower might stop working completely, and you'll end up without any heat.

3. Popping or Banging Noise

A popping or banging noise is very common. These noises, most of the time, come from the air ducts as they expand and contract. It's actually pretty harmless. However, if there are significantly loud banging or popping sounds, then it can be an issue with combustion in the furnace. If not repaired immediately, this can put a lot of stress on all the parts of the furnace.

4. Thwapping Sound

This sound might indicate that there is something stuck in the blade of the blower. Moreover, this sound can also be heard if there is something stuck in the housing of the furnace. Even if the noise is not very loud, you should get your furnace checked by a professional technician to get the problem resolved as soon as possible. Not taking any action can cause severe strain on the motor, which can result in a major breakdown of the furnace.

No matter how strange the sounds your furnace makes, call a professional technician to look into it to avoid further inconvenience.
