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:
AIR CONDITIONING/HEAT PUMP 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 coil clogging and
compressor damage. It also ensures adequate airflow for comfort and
improved air quality within the occupied space.
ü
Check evaporator &
condenser coils for excessive dirt accumulation.
A clean evaporator coil is
essential for proper system capacity and comfort. A dirty coil will
cause the same damage to the system as a dirty air filter. A clean
condenser coil is necessary for proper condensing temperature and
affects capacity levels and system efficiency. A clogged coil will
destroy the compressor and overload the condenser fan motor.
ü
Disassemble outdoor
unit & wash dirty condenser coils, if necessary.
This will usually necessitate an
additional cost to the Preventive Maintenance Agreement.
ü
Check blower &
condenser motor brackets for breaks or cracks. Vibration and unbalance can
weaken and break brackets causing damage to coils and the surrounding
area.
ü
Check setscrews on
fan & blower wheels for tightness and centered in housing. Setscrews
sometimes work loose and cause misalignment resulting in poor airflow
and eventually damage to the fan or blower.
ü
Check blower wheels
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
Check refrigerant
charge, pressures, and temperatures. An incorrect refrigerant charge can
easily go unnoticed and increase operating costs. More significantly, an
improper charge will damage the compressor.
ü
Check superheat and
sub-cooling. Accurate
diagnostic tests allow fine-tuning of your system. They also will
indicate potential problems, which can be eliminated. Records are kept
of your systems history.
ü
Check compressor
terminals for overheating due to lost continuity. A damaged compressor terminal
usually requires compressor replacement. This may be avoided if caught
in time.
ü
Inspect controls
and safeties for proper operation. Controls and safeties that do not
function properly can increase operation cost and cause other components
to fail.
ü
Check compressor
contactor contacts for pitting or burning. Manufacturers claim this condition is
the leading cause of compressor failure in three phase compressors.
Timely replacement can avoid compressor failure.
ü
Lubricate motors
and bearings if applicable.
Motor life can be extended with proper lubrication.
ü
Check for burned
wires & terminals.
In time some wires & terminals lose continuity and overheat.
ü
Check and tighten
electrical connections. Loose connections cause wire overheating which can
cause compressor or motor failure and frequently causes fires.
ü
Check condensate
drain for blockages. Clogged
drains result in overflowing, which causes damage to equipment and
building.
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 defrost
controls & auxiliary heaters in heat pumps.
Faulty defrost controls can damage coils & compressors and go
unnoticed until shocking electric bills come.
ü
Check system
overall operation.
