When your furnace is running during cold weather, you have a\ngood idea of what kind of noises it makes. A modern furnace won\u2019t make a\nracket, but it does create a blanket white noise of air moving through the\nvents. When you\u2019re near to the HVAC cabinet, you\u2019ll be able to hear the burners\nrunning and the noise of the blower fan and its motor. <\/p>\n\n\n\n

But if your furnace is making unusual sounds, ones you aren\u2019t accustomed to hearing, you may feel worried something is wrong. Is it an emergency that needs 24\/7 services from a Smyrna, DE, HVAC<\/a> contractor? Or is it maybe nothing and you\u2019re overreacting?<\/p>\n\n\n\n\n\n\n\n

Before we explore some of the possibilities below, we want\nto reassure your that you\u2019re never overreacting when it comes to concerns about\na furnace. It may end up as small issue, but you\u2019ll still be thankful you\ncalled for professional to make sure of it.<\/p>\n\n\n\n

Banging and clanging from the vents<\/h2>\n\n\n\n

A sound like metal warping isn\u2019t uncommon in HVAC systems,\nsince it\u2019s often the sound of metal ductwork enlarging and contracting as heat\npasses through it. However, this may also indicate the ductwork has damage and\nneeds duct testing and sealing. If the sound is more mechanical, you may have a\nproblem with a bent blower fan blade or a loose part. Check with the sound from\nthe cabinet. You\u2019ll probably need to call for repairs for this.<\/p>\n\n\n\n

Shrieking and grinding<\/h2>\n\n\n\n

These are more extreme mechanical noises, and they are a\ngood reason to feel concerned. Shrieking is a warning that the bearings in one or\nmore of the motors is wearing down. Bearings can be replaced, and they need to\nbe before wearing down completely and causing permanent damage to the motor. A\ngrinding sound is likely a motor that\u2019s already burning out\u2014you may notice an acrid\nsmell as well. Call for emergency repairs to fix this.<\/p>\n\n\n\n

Rattling cabinet<\/h2>\n\n\n\n

This might be a simple problem: the cabinet door is loose.\nShut and latch it again to see if it fixes the problem. If it doesn\u2019t, the\ncabinet itself may be loose or the rubber on its feet has worn down.<\/p>\n\n\n\n

Whooshing\/booming<\/h2>\n\n\n\n

An abrupt \u201cwhoosh!\u201d noise from the furnace during its start-up\ncycle means the burners are having a delayed ignition for some reason. Gas is\nentering the combustion chamber and building up before it ignites, and the\nlarge amount of gas all ignites at once in a large noise. You\u2019ll need to have repair\ntechnicians find out what\u2019s preventing standard burner ignition, and they may\nneed to clean the burners.<\/p>\n\n\n\n

Clicking<\/h2>\n\n\n\n

If the furnace clicks as it tries to turn on, it probably\nmeans the electronic ignition system is dying and will need technicians to replace\nit. If the clicking sound comes after the blower fan turns off, this is a major\nconcern because it may mean a cracked heat exchanger\u2014and that\u2019s a health hazard\nfor your home! Shut off the furnace and gas to the furnace, then call for emergency\nrepairs.<\/p>\n\n\n\n

Keep in mind that you can\u2019t perform furnace repairs on your\nown. When in doubt, always call on the licensed pros.<\/p>\n\n\n\n
