Hi Mike,

I am in Arizona (abt 50 years now) and the weather is definitely warmer.
We keep the house at 84 degrees but the shack is routinely around 92 to 93
degrees during the day due to numerous computers, radios and amp running.
I have a ceiling and floor fan running as well so I can stay relatively
comfortable but sometimes will leave the shack for another room to cool

I plan on adding a split unit to my shack before next summer that will
cover around 200 square feet.  It is called a ductless mini-split.  N6WIN
(ND7K) has one for his shack and it worked very well with 3 of us in the
shack.  Pretty low cost to run but $2.5k to $3k to purchase and install (by
a professional a/c person).  Humidity is only an issue in July/August
here.  I am talking around 50% or so.  It is 46% today but was over 70%
this past Friday through Sunday with a ton of rain but temps were in the
80's.  50%+ gets a little sticky for a desert dweller.

I tolerate heat pretty well but not the cold.  Opposite of you. Without the
ceiling and floor fan though I could only stand it for a bit at a time.
That is my reason for wanting to add A/C in the shack.  I could use it for
heat as well in the winter time but I find the shack stays comfortable
during those months.
