Compared to an air conditioning unit, a gas furnace is really a pretty
simple piece of equipment, with only a few significant components. The
major consideration is the heat exchanger, for if the heat exchanger becomes
cracked the furnace must be replaced. A cracked heat exchanger poses both
a fire hazard and a carbon monoxide danger.
Do not mess around with a cracked heat exchanger!
- A second component which requires periodic attention is the blower motor.
If you hear odd noises coming from your furnace, chances are the blower
motor has worn bearings and/or something is amiss with the blower assembly.
In either case, a competent service technician can make repairs. Or, if
the furnace is over 10 years old you may want to balance the cost of repairs
against a furnace replacement.
- Finally, the burners in your furnace will occasionally become dirty and/or
rusty. Routine maintenance will keep this from becoming a problem. Very
dirty burners lead to uneven flames and must be cleaned.
