OK. I get the point it's certainly worth considering. Hard to assign the $
value to the comfort but easier to assess if extra $xxx is worth being
comfortable during these few days. In reality over a longer period of time
(even only 10 years) the per very hot day cost might be not that high and
therefore the return on investment might be there. I need to see what the
price diff is between the units and associated costs.
Thx

Good point but if it is possible to get down to a more comfortable 75F
(which I used for the design param) then why not. Looks that with the
adjusted dry/wet bulb values I will be able to achieve it with a 5 tons
unit.

Let me rephrase: How much are you willing to pay for the
difference between 72 degrees and 82 degrees, on the
three to six 105 degree days you might encounter per year?

Is that more or less than the price difference for the
next smaller AC unit?
