H blisstout,

Thank you for your question.

Self Sufficiency Plans and Pamphlets

Evaporative Cooler Plans (Swamp Cooler)  7th from top of page

"These plans describe how to build swamp coolers ( evaporative coolers
) small enough to cool a single room and large enough to cool your
whole house. Coolers of this type reduce the average room temperature
to 66 degrees using 1/10 the electrical power of a conventional air
conditioner. The parts cost to build the large swamp cooler are $100
to $200. It is cheaper and easier to build your own swamp cooler which
works as well or better than a commercial unit, buying a new cooler is
should not be considered. $9.95, delivered via email."

A bit of an aside, I realize, but did you know that the ancient
Egyptians also used evaporative coolers:

They even used them to make ice!

Because right now, where I live it's 111 degrees F degrees in the
shade, the humidity is 2%, and the dewpoint is 15 degrees F - an evap
would work very well.  My neighbor has one running and the house is
quite pleasant.  I'm running the a/c at full speed.  :)

There is finally a do-it-yourself guide to servicing, repairing and
enhancing the performance of your evaporative "swamp" cooler yourself
and save lots of money.  The title of this great guide is Easy Cooler
Care.  Unfortunately it's not available in the hardware stores.  You
can get it at or or it can be special
ordered from all the major bookstores.

I hope this info helps you save money.  Those guys that set up coolers
for the season charge way too much!!  It's just way too easy!  This
book shows you how easy.
