Loud intermittent Metallic sound from Heating Unit
 
Hi,
From couple of days, a metallic sound like (bell ringing continously) comes from Heating unit when it is blowing the air.

The sound doesn't come everytime the Heating unit start blowing air, it is coming intermittently.

Please assit.

Thanks
UY

Could be soooo many things. The blower could be out of balance and vibrating. A damper in the duct work could be fluddering when the air is blowing past it. Try and follow the sound if possable to narrow down its locaton
