Furnace maintenance is a very important part of the efficient operation of a warm-air heating system and should never be neglected. The manufacturer of the heating equipment will provide recommendations for proper maintenance, and these recommendations should be carefully followed. By doing so, you will extend the life of the equipment, improve its efficiency, and reduce operating costs. Certain maintenance recommendations are general in nature and will apply to any type of furnace regardless of the fuel used.

These general maintenance recommendations are as follows:

1. Always read and closely follow the manufacturer's maintenance instructions (if they are available).
2. Check gas and oil pipes for leaks.
3. Check and clean (or replace) air filters.
4. Clean the furnace once a year (preferably before the heating season starts).
5. Oil the motor of a gas or oil burner two to three times each year.
