Cleaning a Furnace

Dirt is the biggest enemy of your furnace. It can waste fuel and drastically lower efficiency. In some cases, it can even cause the furnace to overheat. Dirt affects all components of your furnace, so cleaning is the most important part of regular maintenance. The three parts of the furnace that should be cleaned: the filter system, the blower and the motor.
The furnace filter should be replaced or cleaned at the beginning of the heating season and about once a month during periods of continuous use. To check the filter, take it out and hold it up to the light if it looks clogged, replace it with a new filter of the same type and size regardless of the length of time it has been used.
A disposable furnace filter consists of a fiber mesh in a cardboard frame. The size of the filter is printed on the edge of the frame. An arrow on the edge of the frame indicates the correct direction of airflow through the filter. Air flows from the return-air duct toward the blower, so the arrow on the filter should point away from the return-air duct and toward the blower.
A permanent filter is usually sprayed with a special filter-coating chemical, available at hardware stores and home centers. Clean this type of filter according to the manufacturer's instructions, which are usually attached to the furnace housing.
