You should expect a service technician to check the follow
ing items during an annual inspection. Power to the unit
must be shut off for the service technician's safety.
Fresh air grilles and louvers (on the unit and in the room
where the furnace is installed) - Must be open and unob
structed to provide combustion air.
Burners - Must be inspected for rust, dirt, or signs of water.
Vent pipe - Must be inspected for signs of water, damaged
or sagging pipe, or disconnected joints.
Unit appearance - Must be inspected for rust, dirt, signs
of water, burnt or damaged wires, or components.
Blower access door - Must be properly in place and pro
vide a seal between the return air and the room where the
furnace is installed.
Return air duct - Must be properly attached and provide
an air seal to the unit.
Operating performance - Unit must be observed during
operation to monitor proper performance of the unit and the
vent system.
Combustion gases - Flue products must be analyzed and
compared to the unit specifications.
Problems detected during the inspection may make it nec
essary to temporarily shut down the furnace until the items
can be repaired or replaced.
Pay attention to your furnace. Situations can arise be
tween annual furnace inspections that may result in unsafe
operation. For instance, items innocently stored next to the
furnace may obstruct the combustion air supply. This could
cause incomplete combustion and the production of car
bon monoxide gas.
