Issue Possible
Cause
Solution
My air conditioner is
not cooling at all.
Unit is not operating in
cooling mode.
Set the unit to be in
cooling mode, and
lower the set
temperature (pg. 13).
The compressor is not
on.
The compressor may
take up to 3 minutes to
turn on, or longer if it is
too warm.
The ambient
temperature is too
high.
Lower the room
temperature to be
below 90°F degrees.
The filter may be dusty
or blocked.
Clean the filters.
(pg. 16)
Blocked exhaust port.
Remove any
obstructions in the
exhaust hose and port.
My air conditioner
blows cold air, but
does not lower the
room temperature.
The unit is not vented.
The unit must be
vented. (pg. 4)
The area of the room
is too large.
Minimize the size of
the area to be cooled,
i.e. adding a drop
ceiling. Use more than
one unit to cool the
area, or use a larger
unit.
Open windows and
doors.
Close any open doors
and windows.
Too many heat
sources.
Remove or shut off
additional heat
sources such as radio
equipment, servers,
etc.
The room/garage may
be inadequately
insulated.
Properly insulate the
room to be cooled, i.e.
using fiberglass.
The ambient
temperature is too
high.
The unit may not work
if the room
temperature is above
90°F.
Direct sunlight is
heating the room.
Close curtains or pull
down blinds, and
minimize the direct
sunlight into the room.
The filter may be dusty
or blocked.
Clean the filter and
replace it if needed.
Dirty condenser coils.
Carefully vacuum the
coils clean.
Obstructed air intake
or exhaust ports.
Remove anything
blocking the ports.
NOTE:
If the ambient
temperature is above 90°F the
unit may not blow cold air.
