My shack is in the basement and there is no window space large enough 
for an A/C.  I have thus far resisted purchasing a portable non-window 
based unit although I may reconsider.

I don't ever need A/C between October - April; and during the Winter 
months it can be absolutely freezing even in SO2R mode with two amps - 
that's because heat rises and cold air sinks - right to the floor level 
where my feet are.

Between May - September the heat and humidity gradually build in the 
basement - and in July - August the humidity is very bad - and with more 
water vapor in the air, the temperature stays that much warmer than as 
compared to when there are low levels of humidity.  The heat/humidity 
can really sap your energy - it makes me sleepy very quickly even when 
operating in shorts and a T-shirt.  A large fan helps but that creates 
blower noise and very humid air blown at you is not very cooling.  A 
high powered window A/C would definitely help the score!

In Western CT our weather can be extremely unpredictable during WPX - I 
have seen years when it got down into the upper 20's at night and other 
years when it was close to 100 F.  Most of the time WPCW is ok but IARU 
and WAE can be rough to operate in full SO2R mode with two amps.

I would suggest to anyone to put a good size A/C in their shack if they 
can - better to be too powerful than not enough!  The additional score 
generated per $1 spent on A/C may be more cost-effective than almost any 
other equipment in or out of the the shack!
