The furnace uses a part called the air handler to circulate air throughout the house. The part is essentially a large motor with a fan attached to it. A lot of friction is generated by the motor during operation, so to help cope with it the system is equipped with a number of oiled bearings. These bearings lessen the friction greatly, but they do wear out over time.
As the bearings wear down, the friction on the air handler increases and produces a loud grinding sound. If you hear this sound, you should have the bearings in your furnace replaced as soon as possible. Otherwise, the air handler motor may overheat and burn out.
The burner assembly is the part of the furnace that ignites natural gas in order to generate heat. Over time, carbon particles collect on the burner assembly jets. Eventually, the burner assembly will become so clogged that it starts to ignite later than it should. When the assembly finally ignites, it burns through all of the excess gas at once and generates a loud booming sound. Getting your burner assembly cleaned should take care of the problem for you. Make sure you schedule it quickly, though, before the assembly gets too clogged to ignite at all.
Rattling or banging noises coming from your furnace could be a sign of loose or broken components within your furnace. Over time, the vibrations and operational stresses can cause screws, fasteners, or e components like the blower wheel or motor mount to dislodge and damage your furnace. Contact us for regular furnace maintenance in Denver to stay ahead of the issue and identify problems before they get out of hand.

You may need the belt adjusted or the blower motor tweaked and lubricated to mitigate these sounds and the efficiency of your furnace.
