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.)
