Popping. Do you hear a distinct popping, tinny sound in your home’s vents every time you run your heater? You might hear mild popping sounds whenever you turn on your home’s heater because your home’s vents are expanding or contracting depending on the temperature change. This is normal.
Why does my heater make noise?
A loud rumbling sound coming from the furnace is usually due to an issue with the blower wheel. A faulty burner could be causing the noise, or the noise could also be caused by rapid expansion and contraction of the air ducts. The issue is common when the ducts are made of metal.
