What
size portable room air conditioner do I need.
The cooling capacity of
an air conditioner is measured in British Thermal Units (BTU),
and the capacity you require depends mostly on the size of the
room you need to cool. If you buy an air conditioner that is to
small for the room it will not cool adequately. If you buy one
that is too large, the air conditioner will cool the room before
it dehumidifies and this can leave you feeling clammy. For
larger areas, sometimes two smaller units are more efficient
than 1 large unit.

Make
any adjustments for the following circumstances:
(energystar.org)
Heavily shaded rooms,
Reduce capacity by 10%.
Very sunny rooms,
Increase capacity by 10%.
If more than 2 people regularly occupy the
room, add 600 BTUs for each additional person.
If the unit is used in a kitchen, increase
capacity by 4,000 BTUs.
Consider where you
install the unit. If you are mounting an air conditioner near
the corner of a room, look for a unit that can send the airflow
in the right direction.

Venting / Exhausting
Do portable
air conditioners require venting?
Yes, all portable air conditioners
require some type of ventilation. It is important that you vent
the hot air outside of the room you are trying to cool.
Our entire
units comes with hoses to vent the exhaust and window filler
kits to allow you to properly vent out of most windows. However,
you do not need to vent the hot air out a window. The window
venting kits also fit most sliding glass doors ( if you make
modifications , or you may make a custom modification and vent
the exhaust through a wall do not install exhaust hose into a
drop ceiling or anything that does not vent outside
