Furnace Is Making Odd Sounds

Furnaces are known for their strange sounds. Normal sounds you may hear are small little pops or hums as the unit runs. When your furnace is noisier than normal or you start hearing a noise you have actually never ever heard in the past, this typically indicates that there is something wrong with your furnace and it may be time to talk to your HVAC technician about some maintenance and repair work. Here are 3 furnace sounds that you need to not overlook.

1. Scraping Noises
If your furnace starts to make scraping noises, particularly the noise of metal scraping metal, something is most likely loose and requires to be fixed instantly. There is probably an issue with your blower wheel. If your blower wheel is broken, your heating system will not have the ability to effectively heat your house. Any problems with your blower wheel need to be fixed by a technician.

2. Loud Pop or Bang When You Turn On Your Heater

When the burners lastly ignite, you will hear a loud pop or bang. These small surges can harm your furnace and split your heat exchanger, which can be a costly repair work. So if you begin to hear this kind of noise, it’s a great concept to speak with a technician right now prior to excessive damage is done.

If you start hearing a popping sound, there may be some issue with your ducts that may need to be repaired such as small ducts, closed vents, lightweight ducts, or a blocked air filter.

3. Screeching Noises
A high-pitched screeching sound could mean a variety of things, however usually, it is because of a part that needs to be replaced or fixed. Run-down parts such as a frayed blower belt or a malfunctioning blower motor can create these noises and can cause problems for your furnace that will be more major repair work. These are typically simple fixes, but it is best to get them fixed before they trigger any damage to your furnace.

Talking to Your Professional About Routine Maintenance
Of course, these are not the only uncommon noises your heater can make. Whenever you hear strange noises from your heater, it’s an excellent idea to talk to a professional. Neglecting these sounds can cause more major repair work later. If you begin hearing them, it’s important to make sure that they are fixed as soon as possible. Making sure that your technician carries out routine maintenance can keep your furnace from making any weird noises in the very first place.
