The room air conditioner sizing
chart shown below offers an
accurate estimate for cooling
needs under most situations.
The drawback to sizing charts
is they don't take into account
many of the variables that
affect overall performance.
One of the variables that affect
the performance of a room AC
is geographic location.
For instance, an 8 or 9,000 Btu
air conditioner would provide
sufficient cooling for a 400 sf.

But to cool the same sized room in muggy
Miami, you might want to consider an AC in
the 10 to 12,000 Btu range.
Up-sizing might also be necessary for a
family room frequented by multiple
occupants (people add heat), the kitchen, or
south facing rooms.
Room air conditioners with the Energy Star
label will consume less electricity than
unrated models. An EER (Energy Efficiency
Rating) of 10 or more is very good.
Although room air conditioners with higher
efficiency ratings are marginally more
expensive, they'll cost less to operate in the
long term.
Also, many Energy Star rated room air
conditioners qualify for rebates from local
utility companies.
