Now if I lived in San Diego or Kapalua, I'd probably give the exact opposite answer. Actually, if I lived in Kapalua I'd be on the 17th green and not reading this. But I digress...
Now I do spray finishes in summer here. Have to. So I do put up with evacuating all the conditioned air from my shop, which my split AC units have to make up. It's not horrible by any means, but it does need to be taken into consideration. And I have to deal with high levels of humidity from the makeup air brought into my finishing room. So very rapidly the 72 degree, 48% RH goes up to 80 degrees and 75% RH. Not intolerable, but it does show just how much things can change quickly by sucking out all of the shop's conditioned air, and replacing it with outside air. I'd imagine that mid winter in coastal NH, that could get ugly. I know, I used to live about 30 miles from there.
