Well, after a hot week here in North Texas, decicded to have a real system installed. Getting too old to be screwing around with a window unit through a roll up door and nothing when I'm not there. I looking into mini splits first. Prices have gone up a lot. Only a couple rando brands come precharged, Mr Cool and one other (no thanks). LG, Mitsu, not so much, so you'll still need to hire someone. My guy, who did my house a while back, put in a regular 3.5 ton split system. Just the sheer size of the fan and coils make me really doubt a similar sized mini split could complete. My guy said the mini splits have a different compressor type so they do preform impressively. Just looking at one: 42k LG with heat pump. It's at least as much as I paid my mine. I bet mine has quite a bit more CFM and I can add ducting later if I want. All said and done with install and a cage around the condenser, it was 7k (barf) but these Texas summers are no joke. If we get multiple weeks in the triple digits (it happens), I'm not going to be missing that 7k at all.
