What Are The Heater Noises Happening Inside Your House?

Are you Concerned About Heater Noises?

As the days get increasingly cool, you’re likely relying more and more on your heater. As you do, you might find it making some alarming or unsettling noises. While these noises might seem concerning, they can be caused by a number of different factors, some of which are easily resolved and others that require more substantial repairs.

If you’re hearing noises from your heater, the good news is that you’re not alone. This is a common complaint from homeowners. Here are some tips to help you determine the cause of heater noises and if you can resolve the issue, or if you need to contact an expert for heating services

The Cause of Loud Banging Noises

banging noisesOftentimes, banging noises are caused by dirty burners. Over time, dirt will build up in your system. If burners are not cleaned, they can interfere with ignition, which causes gas to build up in your furnace.

When your system does finally ignite, it will result in a small explosion caused by the buildup of gas. This explosion causes a banging noise.

As you might imagine, this can present safety issues and issues for your furnace. Avoid these risks by ensuring that your different burners are regularly cleaned and igniting properly.

Hearing Squealing Sounds?

A squealing sound in your heater often means there’s an issue with either the blower motor or fan belt. It could mean that parts on the motor need to be replaced or it could be as simple as some of those components being misaligned. If it’s an issue with the fan belt, it could mean that the belt is loose or that it needs oil.

If you’re comfortable tightening the fan belt or adding oil to the fan belt, that can be a simple step to try on your own. If that doesn’t work or if you’re unsure of how to maintain the fan belt, it’s best to contact a professional to inspect the furnace.

The Source of Scraping Sounds

A scraping sound is concerning because if the issue is not addressed, it can lead to bigger problems. If you hear a scraping sound from your furnace, it’s best to turn it off immediately and contact a professional. Leaving the system off until the issue can be repaired can help to avoid additional damage or more serious problems.

Hopefully, these tips will help you deal with loud noises from your furnace. Timely identifying and dealing with problems can help avoid an HVAC emergency and can help to minimize damage to your system. If you have any questions or concerns about your heater, remember that it’s always a good idea to contact a local professional to have them inspect and service your system.
