Boilers and furnaces make a variety of sounds while they work to heat your home. As the metal heats or cools, you hear the familiar hums and crackles — you know the sounds. But if you start to hear any unusual noises from your heating unit, it’s a sign that something isn’t working properly and needs to be fixed. Keep your ears open so you’ll know if there’s a problem with heating your home in the chilly winters of Bridgeville, Pennsylvania. Here are some things to listen for.
If there’s a loud bang when lighting the furnace, this can mean the burners are dirty, allowing gas to build up then explode when it finally ignites. This can be dangerous if left unattended, so be sure to call in a heating expert right away to check it out.
A scraping sound means it is likely that something is loose and hitting on another part. It could be it needs to be tightened or replaced if it’s been left too long and caused damage. This could be the blower wheel nut or another component. Call an HVAC expert to diagnose the correct part and get it fixed for you.
Squeals And Squeaks
If you hear a squealing noise when the heat is on, this is most likely a blower fan belt wearing out. The belt wears down or frays over time from the motion of turning the fan. Having it replaced will fix the squeal if that’s the problem. Another option is the blower wheel is squeaky and needs cleaning.
