ISSUE
POSSIBLE CAUSE
SOLUTION
My air conditioner is not cooling
at all.
The 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.
The filter may be dusty or
blocked.
Clean the filter (pg. 17).
The exhaust port is blocked.
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. 3).
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.
There are open windows and
doors.
Close any open doors and
windows.
There are 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
to minimize the amount of direct
sunlight entering the room.
The filter is dusty or blocked.
Clean the filter and replace it if
necessary.
The condenser coils are dirty.
Carefully vacuum the coils clean.
The air intake or exhaust ports are
obstructed.
Remove anything blocking the
ports.
Note: If the ambient temperature is above 90° F 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.
