Efficient room A/C info request [RE-wrenches]

[Kurt Albershardt]

<x-flowed>
I have a similarly-sized and efficient Sharp unit from Costco in my wine cellar, at least until I get the 24V refrigeration system designed/installed.  Beware of power outages, since those electronically controlled units usually wake up in a non-cooling state.

Split systems are routinely >13 SEER and much quieter than window units (at several times the price, of course.)


Oh, and I'm not the one looking for the A/C if that matters...
