Furnace or Air Handler Noise – Loud, Unusual, Grinding, Metal to Metal?

What can cause a indoor furnace or air handler to make abnormal noises?

Here is an actual list of obstacles or issues I have found inside systems, blower compartments and duct work:

  • Dead mouse stuck in a blower wheel!
  • Blower Wheel is actually coming apart at the frame – makes a metal to metal grinding sound – too many dirty air filters over the years!
  • Bad Heat Exchanger in a gas furnace – flame is rolling out of the furnace as the furnace ignites makes a popping noise every time the furnace cycles on- very dangerous!
  • Mylar Balloon sucked into the top of a furnace!
  • Roll of duct tape – been there 17 years!
  • Toys – balls, boats, airplanes, etc.
  • Instruction or paper information sheets from equipment or duct work – been there for years!
  • Partial frames from old air filters!
  • Construction debris from when the home was built! 40+ years ago!
  • Beer Cans, bottles – small and large!
  • Water leaking from an underground water pipe or sewer pipe!
  • Loose insulation from the equipment or from the duct work sucked up into the system!
  • Abnormal Operating Dirt, Dust and Debris!
  • Plenum or Duct has come loose and making high velocity air sound!  (See attached picture.)

 

Huge gap in the duct plenum on this furnace is making a loud noise, but also losing heated and cooled air into the attic. Causing noise and comfort issues, not mention the lost money in wasted energy cost.
