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 qualied servicer.
Replace or Clean Filter
IMPORTANT NOTE: Never operate unit without a lter in-
stalled as dust and lint will build up on internal parts resulting
in loss of efciency, equipment damage and possible re.
An indoor air lter must be used with your comfort system.
A properly maintained 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 lter or lters could be located in your furnace, in a
blower unit, or in “lter grilles” in your ceiling or walls. The in-
staller of your air conditioner or heat pump can tell you where
your lter(s) are, and how to clean or replace them.
Check your lter(s) at least once a month. When they are dirty,
replace or clean as required. Disposable type lters should
be replaced. Reusable type lters may be cleaned.
You may want to ask your dealer about high efciency lters.
High efciency lters are available in both electronic and
non-electronic types. These lters can do a better job of
catching small airborne particles.
Compressor
The compressor motor is hermetically sealed and does not
require additional oiling.
Motors
Indoor and outdoor fan motors are permanently lubricated
and do not require additional oiling.
Clean Outside Coil (Qualied Servicer Only)
Air must be able to 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 rst discussing your
plans with your dealer or other qualied servicer. Restricted
air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 airow. If cleaning of
the outdoor coil becomes necessary, hire a quali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 a condensing unit cover to “protect” the outdoor
unit during the winter, unless you rst discuss it with your
dealer. Any cover used must include “breathable” fabric to
avoid moisture buildup.
• Check the thermostat to con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.
TO AVOID THE RISK OF EQUIPMENT DAMAGE OR
FIRE, INSTALL
THE
SAME AMPERAGE BREAKER OR
FUSE AS YOU ARE
REPLACING
. IF THE CIRCUIT BREAKER OR
FUSE SHOULD OPEN
AGAIN
WITHIN THIRTY DAYS, CONTACT
A QUALIFIED SERVICER
TO
CORRECT THE
PROBLEM.
I
F YOU REPEATEDLY RESET THE BREAKER
OR REPLACE
THE
FUSE WITHOUT HAVING THE
PROBLEM CORRECTED,
YOU RUN THE RISK OF SEVERE EQUIPMENT DAMAGE.
• 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 conrm that it is closed.
• Check for obstructions on the outdoor unit . Con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 qualied
servicer to clean it.
• Check for blockage of the indoor air inlets and outlets.
Conrm that they are open and have not been blocked
by objects (rugs, curtains or furniture).
• Check the lter. If it is dirty, clean or replace it.
• Listen for any unusual noise(s), other than normal
operating noise, that might be coming from the outdoor
unit. If you hear unusual noise(s) coming from the unit,
call a qualied servicer.
