AIR CONDITIONING AND HEAT PUMP HOMEOWNER’S
ROUTINE MAINTENANCE RECOMMENDATIONS
We strongly recommend a bi-annual maintenance checkup be performed
before the heating and cooling seasons begin by a qualified servicer.
Replace or Clean Filter
IMPORTANT NOTE: Never operate unit without a filter installed as
dust and lint will build up on internal parts resulting in loss of
efficiency, equipment damage and possible fire.
An indoor air filter must be used with your comfort system. A
properly maintained filter will keep the indoor coil of your com-
fort system clean. A dirty coil could cause poor operation and/or
severe equipment damage.
Your air filter or filters could be located in your furnace, in a
blower unit, or in “filter grilles” in your ceiling or walls. The in-
staller of your air conditioner or heat pump can tell you where
your filter(s) are, and how to clean or replace them.
Check your filter(s) at least once a month. When they are dirty,
replace or clean as required. Disposable type filters should be
replaced. Reusable type filters may be cleaned.
You may want to ask your dealer about high efficiency filters. High
efficiency filters are available in both electronic and non-elec-
tronic types. These filters can do a better job of catching small
airborne particles.
Compressor
The compressor motor is hermetically sealed and does not re-
quire additional oiling.
Motors
Indoor and outdoor fan motors are permanently lubricated and
do not require additional oiling.
Clean Outside Coil (Qualified Servicer Only)
HIGH VOLTAGE!
Disconnect ALL power before servicing. Multiple
power sources may be present. Failure to do so may
cause property damage, personal injury or death.
Air must be able to flow through the outdoor unit of your comfort
system. Do not construct a fence near the unit or build a deck or
patio over the unit without first discussing your plans with your
dealer or other qualified servicer. Restricted airflow could lead to
poor operation and/or severe equipment damage.
Likewise, it is important to keep the outdoor coil clean. Dirt, leaves,
or debris could also restrict the airflow. If cleaning of the outdoor
coil becomes necessary, hire a qualified servicer. Inexperienced
people could easily puncture the tubing in the coil. Even a small
hole in the tubing could eventually cause a large loss of refriger-
ant. Loss of refrigerant can cause poor operation and/or severe
equipment damage.
Do not use a condensing unit cover to “protect” the outdoor unit
during the winter, unless you first discuss it with your dealer. Any
cover used must include “breathable” fabric to avoid moisture
buildup.
•
Check the thermostat to confirm that it is properly set.
•
Wait 15 minutes. Some devices in the outdoor unit or in
programmable thermostats will prevent compressor op-
eration for awhile, and then reset automatically. Also, some
power companies will install devices which shut off air
conditioners for several minutes on hot days. If you wait
several minutes, the unit may begin operation on its own.

•
Check the electrical panel for tripped circuit breakers or
failed fuses. Reset the circuit breakers or replace fuses as
necessary.
•
Check the disconnect switch near the indoor furnace or
blower to confirm that it is closed.
•
Check for obstructions on the outdoor unit . Confirm that it
has not been covered on the sides or the top. Remove any
obstruction that can be safely removed. If the unit is cov-
ered with dirt or debris, call a qualified servicer to clean it.
•
Check for blockage of the indoor air inlets and outlets.
Confirm that they are open and have not been blocked by
objects (rugs, curtains or furniture).
•
Check the filter. If it is dirty, clean or replace it.
•
Listen for any unusual noise(s), other than normal operat-
ing noise, that might be coming from the outdoor unit. If
you hear unusual noise(s) coming from the unit, call a quali-
fied servicer.
