Issue
My air conditioner is not cooling
at all.
My air conditioner blows cold
air, but does not lower the room
temperature.
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.

Possible Cause
The unit is not operating in
cooling mode.
The compressor is not on.
The ambient temperature is
too high.
The exhaust port is blocked.
The unit is not vented.
The area of the room is too
large.
There are open windows and
doors.
There are 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.
The condenser coils are dirty.
The air intake or exhaust ports
are obstructed.
Solution
Set the unit to run in cooling
mode, and lower the set
temperature.
The compressor may take up
to 3 minutes to turn on, or
longer if it is too warm.
Allow the unit to begin cooling
the area before an ambient
temperature of 90° F is
reached.
Remove any obstructions in
the exhaust hose and port.
The unit must be vented.
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 or
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 the curtains or pull
down the blinds to minimize
the amount of direct sunlight
entering the room.
Clean the filter and replace it
if needed.
Carefully vacuum the coils
clean.
Remove anything blocking
the ports.
