If you use AC and want more humidity removal say it is at 68 outside
and it is raining you can run it on low to remove twice the humidity as
on normal high and not cool as much. You can run it better on Humidistat
at lower outside temps. You save on electric winter and summer. But
it will heat more evenly if that is an issue. Its like getting a fancy
car, more to break, more to repair. Ive calculated heating season
payback at 6 yrs. But get the 10 yr warranty. Also I dont beleive
electric costs to remain stable for 4 yrs thereby increasing payback.
