Especially in the summer. Most of us have oversized units that don't run for long enough to remove humidity in the air so they end up very humid inside.
My current house I have calculated can keep my house cooled to 75 from ~135 degrees and warmed to 70 degrees from -41 degrees. Needless to say i didn't freeze in the -5 the other day as the furnace only ran for 9 hours. lol
But yeah typically the newbies down here trying to do spray foamed sealed houses end up delivering extremely efficient but humid and moldy houses.
