Sounds Your Furnace Shouldn’t Be Making

woman-holding-hand-to-ear-to-listenWe’re sure it’s easy for some homeowners to ignore some of the noises that the various appliances in their homes make. It’s easy, after all, to deny that something may be amiss because repairing it can be an expensive nuisance. However, there are just some noises that just shouldn’t be ignored. While a slight rattle, for example, might just indicate a loose panel, it alternatively could be something more ominous, such as a cracked heat exchanger, which could potentially lead to a carbon monoxide leak.

Here at Canella, we understand just how vital it is to protect yourself and your family. If you do find yourself heating some suspicious sounds, don’t hesitate to give our number a call and schedule a visit from one of our technicians. In the meantime, read on to learn what the different sounds are that you should watch out for–or rather, listen for!

Screech!

A loud screeching noise is most likely an indication that something is amiss with the blower motor of your furnace. A malfunctioning blower motor means that the blower fan won’t work as it should, and as a result, your furnace will be unable to circulate warm air throughout your home successfully.

This may just simply mean that your blower motor is in need of desperate lubrication, however, it could also suggest that the fan has stopped altogether. To properly diagnose this problem, it’s important that you contact a local HVAC contractor. Once the problem is diagnosed, we can advise you on the next steps that should be taken.

Clank!

If you hear something that resembles metal striking metal, then you probably are hearing metal striking metal. This can be the indication of a serious issue with the furnace’s blower wheel. If this is the case, then you should turn your furnace off and contact a professional right away, so you can avoid further damage to the wheel. More damage to the wheel means more damage to your budget!

BOOM!

Typically, a bang or a boom that you might hear coming from the furnace is the sign that your furnace has dirty burners, and this can actually be a harmful issue. The noise you’re hearing is caused by a delay in ignition due to dirt and buildup. The gas builds up, and then when it ignites, a small explosion occurs inside the furnace.

We never recommend that homeowners try to clean the burners themselves. There is too much room for error here, and the last thing you want to do is spend more money than necessary. It’s always best to call in a professional, particularly when dealing with gas lines.

Rattle!

Rattling may be a really benign sound–for instance, it could be nothing more than a loose panel. However, a broken heat exchanger, as we mentioned above, could also be the cause. Or it could be a component that’s become loose. One loose or damaged component can lead to a domino effect inside the system, eventually leading to a breakdown.
