Parts information
Replacement parts are available from your local
contractor or dealer.
Extended warranty
Special warranty packages (called performance promise
plans) are available through your contractor. These
packages reduce the potential cost of service calls
following the first year of operation on your cooling (or
heating and cooling) system.
Some efficiency dos and do nots
• Do not constantly adjust the thermostat. Adjusting
your thermostat setting does not make your system
heat or cool any faster. Set your thermostat to a
comfortable setting and only adjust it when required.
• Do not restrict air circulation. Placing furniture, rugs,
and other obstacles where they interfere with air
vents makes your system work harder to achieve a
comfortable temperature level. This requires more
energy, which means greater energy costs.
• Do not locate lamps or other heat-producing
appliances (radios, TVs, heaters) near your
thermostat. The heat from these items gives your
thermostat false information about the temperature
in the room.
• Do select a comfortable thermostat setting, but keep
in mind that moderation in temperature selection
saves energy.
• Do turn on your kitchen exhaust fan when cooking
and your bathroom exhaust fan when showering.
Also, make sure your clothes dryer is properly vented.
If these items are neglected, excess heat and humidity
may be created, causing your air conditioning system
to run longer.
• Do set your thermostat a few degrees lower than
normal several hours before entertaining a large
group of people in a relatively small area. People give
off a considerable amount of heat and moisture in a
closed area.
• Do keep drapes and venetian blinds closed when
practical. These items provide insulation against heat
loss or gain.
• Do contact a qualified service person to make repairs
or adjustments to your system.
Characteristics of heat pumps
Constant heat
Heat pumps have a cooler supply air temperature than
furnaces. The common practice of over-sizing furnaces
contributes to an off-and-on again operation with short
blasts of hot supply air. The heat pump system is sized
more closely to the heating needs of your home. Heat is
supplied at a lower temperature over a longer period of
time to provide a more constant heat, and it may give you
the impression that your system never stops running.
Water run-off
During the heating cycle in mild weather, you may notice
water running off the outdoor coil. Moisture from the
air condenses on the outside surface of the coil, where it
gathers and runs off. This is a normal part of operation
and does not indicate a leakage.
Outdoor coil defrosting
At certain outdoor conditions (low temperature,
high humidity), frost may build up on the coil of the
outdoor unit. To maintain heating efficiency, the
system automatically defrosts itself. Steam rising from
the outdoor unit is normal and is an indication of
correct operation. The vapor cloud only lasts for a few
minutes. When the defrost cycle completes, the system
automatically switches back to heating. Auxiliary heat
is automatically energized to maintain comfort during
defrosting.
