Maintaining the Home:
Interior Maintenance
Furnace Care
All heating systems should be checked periodically by a professional. Consult the installation manual for maintenance frequency or ask the dealer who installed the system how often professional inspections are recommended. Generally, oil burning units and heat pumps should be inspected annually; gas fired units and electric furnaces every two to three years.
Inspect the flame color in gas fired units annually. The flame should be primarily bluish in color. If it is yellow or if flames are lifting off the burners, call a professional to adjust the system.
Inspect the walls of the heat exchanger for deterioration, corrosion, debris, soot, mineral deposits or cracks. If any damage is evident, consult a professional to clean or replace the unit, depending upon severity. If the area only needs cleaning, you can perform this task. Ask the heating and cooling contractor to show you how during his/her next visit, or consult the installation manual.
Oil the motor and fan in your forced air heating system at the beginning of and during the heating season. The heating contractor can show you how or consult the furnace installation manual.
Clean or replace the air filter in a forced air heating system. Check the filter monthly during the winter. Consult the installation manual for directions and recommended replacement frequency.
Annually inspect the insulation on heating supply ducts/pipes to insure that it is secure. Refasten any loose insulation.
Check each room in the home for the level of heat output, especially rooms farthest from the furnace/boiler once a year. Uneven heat distribution indicates the system is out of balance. Consult a heating contractor.
Safety/Temperature Controls
Inspect and clean the thermostat annually. Use a soft brush to remove dust and lint. Use soft white paper to clean the contacts. Ask the heating contractor to demonstrate the procedure.
Each year, check to see that the master shutoff switch to the heating system is operational. If it does not shut off the system, consult a professional.
