Although an electric heating system does have advantages, its operating cost generally makes it less desirable than any of the other furnace systems available today. The high cost means that minimizing heat loss caused by improperly installed ducts or inadequate insulation is even more important than with other types of systems. However, their maintenance costs tend to be lower over the lifespan of the furnace than other types of heaters [source: Trained Eye Home Inspection].
For maximum energy efficiency, have a professional service person clean and adjust your electric furnace every year before the beginning of the heating season. Do not attempt any repairs to the heating elements, electrical connections, relays, transformers, or similar components of an electric furnace; repairs to these components must be made by a professional service person.
The controls of an electric furnace may be mounted on the surface of the housing or installed behind an access panel on the front of the furnace. The access panel may be slip-fit on hooks fastened to the furnace housing with a series of sheet-metal screws. To remove the access panel to the blower, filter and blower motor, slip the panel up off hooks or remove a series of sheet-metal screws.
Electric furnaces are fused at a building's main electrical service entrance. Many electric furnaces are on separate circuits, sometimes located in a separate fuse box away from the main panel. The heating elements of the furnace are also fused, and these fuses are located on a panel that is on or inside the furnace housing.
If changing the fuses or resetting the breakers does not restore power to the furnace, call a professional service person. Do not attempt to repair heating elements, the transformer, heating relays, or power relays. Repairs to these components must be made by a professional service person.
