Dutch and OM, thank you very kindly for the quick reply. The 20' of vertical exhaust was confounding me and I was actually concerned the air wouldn't make it up without the assistance of an inline fan, but if 3,413 BTU + outside ambient temps is all I need to cover then I think I'm in good hands. That is a great formula btw I won't forget it. Funny enough om, I was just thinking about you (as per my regular habit) and that nifty sharp a/c unit sitting so handsomly in one of your setups, but I wasn't aware that there were 2000watts of PSMH there too. Here goes!
