ROUTINE MAINTENANCE RECOMMENDATIONS

We strongly recommend a bi-annual maintenance checkup be performed

before the heating and cooling seasons begin by a 

qualified servicer

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
installer 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-
electronic types. These filters can do a better job of catching
small airborne particles.

OMPRESSOR

The compressor motor is hermetically sealed and does not
require additional oiling.

M

OTORS

Indoor and outdoor fan motors are permanently lubricated and
do not require additional oiling.

Air must be able to flow through the outdoor unit of your com-
fort 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 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 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
covered 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 oper-

ating noise, that might be coming from the outdoor unit.
If you hear unusual noise(s) coming from the unit, call a
qualified servicer.
