Need some troubleshooting tips for those spooky HVAC noises? Never fear! Here’s what you need to know.
Is Your Heat Pump “Wooshing”?
Heat pumps provide both cooled and heated air to your home. They’re incredibly energy efficient
and more common in areas with mild winters, like South Carolina. Chances are you have a heat pump or have a neighbor who does, and the closer you get to winter, the more likely you are to hear a “clunk, whoosh, ting-ting” combo. What does it mean? Nothing of significance. Your heat pump is simply defrosting.
Do You Hear Metal Hitting Metal?
On the other hand, if your heat pump starts to sound like a wind chime, you likely have a problem. Shut it down and check the outdoor unit. Fan blades and other components sometimes become loose and collide with one another. This can cause major damage and render your heat pump useless.
Is Your Furnace Popping?
Sometimes, a second or two after you turn up the heat, you’ll hear a bang or a pop as your furnace starts. This is more dangerous than you might think. The “pop” is the sound of a build-up of gas igniting. It could be a simple fix, maybe as easy as scrubbing buildup off the burner. However, because this could signify a problem with your gas line, it’s best to call a professional right away to check it out.
Is Your Furnace Rattling?
Ductwork often has gaps that lead to shifting noises as the furnace blows. This is normal. An easy fix involves covering seals in foil tape and adding insulation. If you hear rattling from inside the furnace, however, you should shut it off and call for repairs. This noise can indicate a loose or broken component which needs repair before it causes more damage.
