Annual Preventive Maintenance is an investment in your family's future comfort
An
Annual Preventive Maintenance Agreement heads off heating or cooling
problems and gives you priority service over non-agreement
customers. It also gives you a reduced labor rate and parts
discounts. Written reports are given to you on each visit.
What exactly does our Annual Preventive Maintenance program cover? Find out in these checklists:
GAS FURNACE PREVENTIVE MAINTENANCE
ITEMS PERFORMED:
ü
Check thermostat
calibration.
Inaccurate
thermostats affect comfort and operating costs.
ü
Replace air filters
or air cleaner media.
Clean filtering media prevents furnace overheating.
It also ensures adequate airflow for comfort and improved air quality
within the occupied space.
ü
Check blower motor
brackets for breaks or cracks. Vibration and unbalance can weaken and break
brackets causing damage to the furnace.
ü
Check setscrews on
blower wheel for tightness and centered in housing. Setscrews sometimes work loose
and cause misalignment resulting in poor airflow and eventually damage
to the blower.
ü
Check blower wheel
for excessive dirt; wash blower wheel and housing if necessary. Dirt builds
up in the blower wheel vanes and restricts airflow, causing poor
efficiency in the system.
ü
Lubricate motors
and bearings if applicable.
Motor life can be extended with proper lubrication.
ü
Check condensate
drain for blockages on condensing gas furnaces. Clogged drains result in overflowing,
which causes damage to equipment and building. Some furnaces will
lockout when the drains become clogged leaving you without heat.
ü
Check combustion
air blower.
Examining the
blower wheel for rust, corrosion, and blockages can allow for early
repairs before it becomes an emergency.
ü
Check for gas leaks. Vibration can loosen some fittings and joints.
ü
Check for spider nests in air shutters & burner openings. Spiders love gas appliance air
passages for some reason. They frequently build nests which block
combustion air from allowing burners the proper amount of air for
combustion.
ü
Check main burners for deterioration, blockage, or corrosion. A defective burner can cause carbon
monoxide gas and premature heat exchanger failure.
ü
Check flue and combustion air piping for blockages and breaks.
Frequently, nests from insects and
rodents are found in the pipes. Occasionally, ice will build up in cold
damp weather where condensing furnace pipes exit the building. Blockages
can cause furnace shutdown and even damage the furnace.
ü
Check flame sensor signal. Corrosion, positioning, and poor grounding of flame sensor
can weaken flame signal and cause nuisance safety lockouts.
ü
Check gas pressure and adjust if necessary. High gas pressure will cause heat
exchanger failure, sooting, and furnace overheating. Low pressure will
cause inefficient and erratic operation.
ü
Check for proper control operation. Inoperative safeties are a fire
hazard.
ü
Check for flue gas leakage into living space. Even small amounts of leakage into the
occupied space can cause headaches and an ill feeling.
ü
Check condensate drain tubing on condensing furnaces for leaks &
cracks.
Condensate is acidic and will corrode any metal it touches requiring
early furnace replacement
ü
Inspect the
exterior of equipment and replace any missing screws to prevent air
leakage. As much as
25% of conditioned air can escape due to improperly fitted or secured
access panels.
ü
Check furnace overall operation.
