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.
