Furnaces—especially older models—often make noises. Normal sounds are minor pops from the ducts and the humming of the furnace as the blower runs.
Ignoring these noises would be a big mistake since what’s causing them could lead to even more costly repairs (or even costlier replacement) later on. Here are three furnace noises you should never ignore, what’s causing them, and who to call for furnace repair in New Jersey.
A loud scraping noise that sounds like metal rubbing metal or nails scratching a chalkboard probably means something is wrong with the furnace’s blower wheel. If you hear this noise, turn off your furnace ASAP and call a professional for help.
Here are three problems with the blower wheel, from least serious to most serious, that are causing this noise:
Here are two common reasons for the loud banging or popping coming from your furnace:
A high-pitched squealing noise is caused by:
This squealing or whining noise isn’t as big of a deal as the others listed above, but it’s best to get it fixed before it causes any further troubles inside your furnace. An annual furnace maintenance visit every fall can prevent the belt from getting too loose or certain parts from being under-lubricated.
There are a variety of things that can go wrong with a furnace, so this is just a sampling of what could be causing a noise and not a complete list. Even if the strange noise is minor right now, that does not mean you shouldn’t get it checked out because it could snowball into a much larger (and therefore costlier) problem later on.
