We've thought about doing that...a 5000 BTU window shaker that pulls 4 amps running...a heck of a lot less than the big whole house...AC is a NECESSITY in the midwest starting just about any time now until September.
Today is cloudier and with rain moving in this evening....I need to start thinking about painting projects. Built a shed in 2020 I need to pain the trim on, and a little around the windows. which will likely spill out into re-trimming the whole house. Its rock fronted with T1-11 around back.
Next yera the T1-11 is getting replaced with something much better...that stuff is junk Of course when I do that, it means new windows to get more air in the bedroom --- and likely spray in foam insulation, since I'll have the cavities open...maybe some rewiring too....when I"m at that....
While completely unrelated and discussed elsewhere, the honda eu2200 handles the AC perfectly...4amp running, spike to 16 amp on compressor start --- just enough to get a burp....
