Keep the burner area of your furnace clean. Furnaces that require lubrication on the motors and bearings should be attended to by a qualified heating technician once a year. Do not have anything combustible within six inches of your vent pipe. This can cause high resistance and unneccessary heat build up in the furnace. Do not store combustible material such as paint thinners, gasoline, etc. near your furnace.
Filters are in place for the protection of the equipment.
Filters are used to keep dust and dirt from getting into your blower and evaporator coil, because that could lead to serious problems. If they get clogged, the sytem has to work harder which means that it uses more energy and you have higher utility bills. Every home and system differ as to how often the filter should be changed or cleaned. Most manufacturers recommend changing standard, throw away filters every month, these include the one inch polyester, one inch pleated and fiberglass. Washable filters should washed once per month, we do not recommend washable filters.
