Keep reading to learn some of the top noises that you never want to ignore.
1. Whining Noise
A high pitched noise when you turn your furnace on can mean that the shaft bearings need some TLC. The first thing you will want to do is check if they need oil. You will also want to check if the blower belt or the blower motor are worn or broken.
If you do not feel comfortable checking any of these you can contact a reputable professional like https://www.schneidermechanical.com/ to have them diagnose what is causing the whining noise.
2. Loud Bang
Sometimes people experience a loud bang or a loud pop when they turn their furnace on. This can be caused by a few different things like a dusty furnace ignitor or a dusty furnace burner. When the furnace burner is dirty it can keep the burners from igniting and this will cause the gas to build up and when the gas finally ignites it makes a loud banging noise.
This is a problem that you want to take care of as soon as possible because it can cause a safety problem. One of those explosions can cause the heat exchanger to crack which can result in a carbon monoxide leak. You can also end up having to replace the heat exchanger if it completely goes out which will be a much more expensive repair.
3. Scraping Noise
If you ever hear scraping noises such as metal scraping metal, it means that something is loose and has to be fixed immediately. This means that there is more than likely a problem with your blower wheel.
If the blower wheel ever goes, the furnace will not be able to heat up your home and it will have to be repaired by a tech.
4. Rumbling Sounds
Hearing a gentle woosh is normal when you first turn on a furnace, but if you hear that gentle swoosh turn into a rumble it might be trouble. If the rumbling sounds continue after the furnace goes through a heating cycle and switches off it might be a burner issue.
This can lead to high levels of carbon monoxide inside your home, therefore you want to turn it off ASAP and call a tech.
