AIR CONDITIONING HOMEOWNER’S ROUTINE MAINTENANCE RECOMMENDATIONS
We strongly recommend a bi-annual maintenance checkup be performed
before the heating and cooling seasons begin by a
qualifi ed servicer
.

IMPORTANT NOTE:
Never operate unit without a fi lter in-
stalled as dust and lint will build up on internal parts resulting
in loss of effi ciency, equipment damage and possible fi re.
An indoor air fi lter must be used with your comfort system.
A properly maintained fi lter will keep the indoor coil of your
comfort system clean. A dirty coil could cause poor operation
and/or severe equipment damage.
Your air fi lter or fi lters could be located in your furnace, in
a blower unit, or in “fi lter grilles” in your ceiling or walls. The
installer of your air conditioner can tell you where your fi lter(s)
are, and how to clean or replace them.
Check your fi lter(s) at least once a month. When they are dirty,
replace or clean as required. Disposable type fi lters should
be replaced. Reusable type fi lters may be cleaned.
You may want to ask your dealer about high effi ciency fi lters.
High effi ciency fi lters are available in both electronic and non-
electronic types. These fi lters can do a better job of catching
small airborne particles.

Air must be able to fl ow 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 fi rst discussing your
plans with your dealer or other qualifi ed servicer. Restricted
airfl ow 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 airfl ow. If cleaning of
the outdoor coil becomes necessary, hire a qualifi ed 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 refrigerant. Loss of refrigerant can cause poor
operation and/or severe equipment damage.
Do not use an air conditioner cover to “protect” the outdoor
unit during the winter, unless you fi rst discuss it with your
dealer. Any cover used must include “breathable” fabric to
avoid moisture buildup.

•
Check the thermostat
to confi rm that it is properly set.
•
Wait 15 minutes. Some devices in the outdoor unit or
in programmable thermostats will prevent compressor
operation 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 confi rm that it is closed.
•
Check for obstructions on the outdoor unit
. Confi rm
that it has not been covered on the sides or the top.
Remove any obstruction that can be safely removed.
If the unit is covered with dirt or debris, call a qualifi ed
servicer to clean it.
•
Check for blockage of the indoor air inlets and outlets.
Confi rm that they are open and have not been blocked
by objects (rugs, curtains or furniture).
• Check the fi lter
. If it is dirty, clean or replace it.
•
Listen for any unusual noise(s), other than normal oper-
ating noise, that might be coming from the outdoor unit.
If you hear unusual noise(s) coming from the unit, call a
qualifi ed servicer.
