Some sounds are normal. The revving of your car engine when you press on the gas, the clicking of your gas stove when you’re cooking food, even the hissing of water coming from your faucet when you turn the dial, these are normal noises. However, there are some appliances in your home that should not make noises by any standards. Your furnace is one of these appliances.
While sure, hearing the sound of your furnace gently depositing heated air into your home is definitely harmless, any banging or clanking noises that it might make are absolutely not normal. Not only are they not normal, but they could also be dangerous as well, which is why a furnace noise should always warranty a call with an HVAC technician. Whether you need furnace repair in Orlando, FL or a whole system replacement because yours is leaking gas, we can be the team to help you get to the bottom of it.
Unusual Furnace Noises
So, you must be asking yourself what kinds of furnace noises are we talking about here? Well, let’s take a look at some of the possible noises, talk about what they could mean concerning the health of your furnace, and then we can approach the next steps to take to address these sounds.
Banging or Booming
No, your furnace is not supposed to sound like a gunshot. This is likely a problem with gas building up in the system, either from dirty burners or a delay in the ignition system. This can actually be a pretty bad problem to have because it could eventually lead to your heat exchanger cracking, which is a recipe for a carbon monoxide leak. Make sure you address this loud noise as fast as possible, both for the life of your heater and so you can finally sleep soundly again!
Clanging or Scraping
While there are a few noises that sound like clanging or scraping, what we really mean by those two words is anything that sounds like metal rubbing against metal. Your furnace has a blower wheel that could be misaligned and constantly scraping against another component, which isn’t an inherently terrible problem to begin with, but it could compound into something much worse later on.
Shut off your system and get it checked on by a professional as soon as you can.
Your furnace is not supposed to run like your car, you don’t want a constant rumbling noise coming from your basement at all hours of the day. A rumbling furnace could signify a dirty burner or even a lack of maintenance, since a pilot light might need to be adjusted or the combustion area might need to be cleaned. Rumbling signifies gas that’s burning unevenly, which can eventually compound into a cracked heat exchanger if you’re not careful.
