My part of Texas has 'way too much humidity for "swamp boxes" but if your
figure is 20% or less during the hottest summer, charts indicate a decent
temperature drop of 20-25 degrees. I went with AC in my 1800 square foot
metal building and I was fortunate to find a very reasonable "take-out" 5
ton unit for cheap. The biggest surprise is the low monthly expense. I
guess I was thinking about the $200 - $300 per month that it takes to cool
my 2000 square foot house 24 hours a day 7 days a week.
I only run the shop unit about 40 to 60 hours a month and the bill is $60 to
$70 for the entire shop including serious lighting and 20 power tools and
welders. A big benefit is the humidity reduction . . which make the
effective cooling much more pleasant and there is NO rust in my shop . .
Make friends with an AC contractor and get in line for a good used
"take-out" unit . .
