It is important that you have your furnace inspected to ensure that it is in good  working condition.

-Be sure all furnace controls and emergency
shutoffs are in proper working condition.

– Leave furnace repairs to qualified
specialists. Do not attempt repairs yourself
unless you are qualified.Inspect the walls and ceiling near the furnace
and along the chimney line. If the wall is hot
or discolored, additional pipe insulation or
clearance may be required.

-Check the flue pipe and pipe seams. Are
they well supported and free of holes and
cracks? Soot along or around seams may be
an indicator of a leak.

-Is the chimney solid, with cracks or loose
bricks? All unused flue openings should be
sealed with solid masonry.

-Keep trash and other combustibles away
from the heating system.
