Heating Systems Info.

All Forced Air Systems: Conventional filters on forced-air systems should be checked monthly and cleaned or replaced as needed. Electronic filters should be checked monthly and cleaned as needed. The manufacturers instructions should be followed carefully. Care should be taken to ensure the interior components are installed in the correct orientation after cleaning.

Noisy blower sections should be brought to the attention of a technician.

Water levels in humidifiers should be checked and adjusted monthly. Interior components should be replaced on an as needed basis. The pad on drum type humidifiers should be replaced annually. The water supply to humidifiers should be shut off for the summer months and activated for the heating months. On systems with air conditioning or a heat pump, the damper in the humidifier ductwork should be closed during the cooling season.

All Hot Water Systems: Radiators and convectors should be inspected annually for leakage (particularly at the valves). Radiators should be bled of air annually, and as necessary during the heating season.

Circulating pumps should be lubricated twice during the heating season. Expansion tanks should be drained annually.

Electric Heat: Electric furnaces and boilers should be inspected by a qualified technician every year to ensure that all the components are operating properly and no connections are loose or burned. The fuses or circuit breakers in some electric systems can be checked by the homeowner.

Electric baseboard heaters should be inspected to ensure an adequate clearance from combustibles. Baseboard heaters which have been mechanically damaged should be repaired or replaced.

Oil Furnaces and Boilers: Oil systems should be checked by a qualified technician on an annual basis. Oily soot deposits at registers of forced air systems may indicate a cracked heat exchanger. A technician should be contacted.

The exhaust pipe from the furnace or boiler should be checked for loose connections or corroded sections. The barometric damper on the exhaust pipe should rotate freely. The chimney clean out should be cleared of any debris. The oil tank should be inspected for leaks. Soot on the front of the furnace or boiler may indicate a draft or combustion problem. A technician should be contacted.

Gas Furnaces and Boilers: If gas odors can be detected, call the gas company immediately. Do not turn on any electrical equipment or use anything with an open flame.

Gas furnaces and boilers should be cleaned and serviced annually. The exhaust pipe should be checked for loose or corroded sections. The chimney clean out should be cleared of any debris. The heat shield (located where the burner enters the heat exchanger) should be checked to ensure that it is not loose or corroded. Burn marks around the heat shield may indicate a draft or combustion problem. A technician should be contacted.
