the unit may not blow cold
air.
TIP: Run the unit before it is
needed. For example, run
the unit in the morning
before the area gets hot,
and continue to run the
unit all day long in order to
maintain a low
temperature.

Troubleshooting continued

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