You've grown accustom to the daily noises your furnace makes, but when your furnace starts to make an unusual noise, it could indicate that you either need routine maintenance or a repair.
Learn the noises your furnace shouldn't be making below.
Banging or Booming
It's not uncommon to hear a boom or bang when the furnace engages, especially in older models. Although, It could be a result from gas build up from a dirty burner or igniter; when the gas finally ignites, it creates a bang. This could be a safety hazard if the heat exchanger cracks in which case you would need a replacement; call a professional immediately if you smell natural gas.
Squealing or Whining
A high-pitched noise could indicate a faulty belt, failing fan motor, or the shaft bearings need oil. These fixes are pretty routine and can be pinpointed with a seasonal furnace tune-up before they become a big problem.
Clicking
Clicking is the most benign noise that can come from your furnace. If the clicking becomes louder or more frequent, it could indicate a faulty flame sensor, loose bolts, or an ignition problem (this requires immediate attention).
Rattling
Rattling metal is never a good sign. It could be as simple as a damaged or loose blower that can be fixed with tightening the screws, or if the rattling worsens, it could mean a complete system failure.
Keeping on top of your regular preventative maintenance is the easiest way to avoid any of these sounds. To schedule your appointment or if you have more questions, call 72 Degrees Comfort Company at 515-965-7272 or email us at office@72degrees.com.
