o If you gas furnace makes a “booming” sound when it comes on, it usually means there is an issue with the burner, such as dirt or rust, that is blocking the gas jets. You should only trust the job of cleaning the burner to professionals. The booming might also be due to a defective gas valve.
o A clicking noise as the furnace turns on sometimes indicates problems with the electrical ignition. If the clicking sound occurs after the blower fan turns off, it can point toward cracks in the heat exchangers, which can lead to carbon monoxide leaks in gas furnaces—so do not hesitate when it comes to calling for repair work.
o This sort of mechanical sound can mean issues with the blower motor, possibly with the bearings. Have technicians look into the sound and see if the motor needs replacement.
o If you have an older furnace that still uses a blower motor fan belt (rather than a direct motor), the eruption of clanging noises from the cabinet might mean the belt has snapped and is starting to strike other parts of the cabinet. Although repairs can fix this, in most cases you should give serious consideration to replacing the furnace with a newer model.Because there can be more than one cause behind a particular furnace noise, you will need repair technicians to diagnose the problem first and then apply the right solution.
