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

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.
