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.

 

If you need help with abnormal furnace, air handler, air conditioning noises call A.I.R. today at 405-618-2AIR or 405-421-5191. Or go to our website at airokc.com and schedule an appointment online.

Please have the noise checked out, you never know what is in your heating or cooling system unless you look or have someone look!

(We look for sound issues or any potential issues of any kind on every heating or cooling semi-annual service appointment. )

It is cold in here! Why? The dog chewed a hole in the heating and cooling duct work!

Hole in the return air plenum/platform.

As you may be able to see from the picture, a dog chewed into the bottom of this return air plenum which is located in the garage. The furnace being located in a garage area is very common, the furnace platform or return air platform/plenum in this case is one piece. So the outdoor air that is in the garage area is being pulled into the heating and cooling system. Then the heating and cooling system must heat or cool the outdoor air, not the conditioned air in the home. And this my friends is not good!

Your heating and cooling system is now responsible for heating and cooling conditioned air that it has conditioned in addition to outdoor air. This system will never keep you comfortable! So, check those HVAC units that are located in the garage. You never know what they have been subjected too in the past few weeks or months and may need to be repaired. Check them especially if you are having system performance problems or concerns.

Pets, bicycles, lawn mowers, cars and really any moving object can penetrate the old sheet rock casings for older systems. And penetrations are bad!

Call A.I.R. Plus if you need help with your system. We would love to help you!

Have a blessed day!
