<div class="moz-cite-prefix">I think I posted to this list 3-4 years
ago about some of my experiments with this. I was scheduled to
have a new pair of heat pumps installed later that week so I
wasn't concerned with ruining the coils. When directly misting
the coils, I recall measuring a ~30% drop in current drawn by the
compressor.<br>
<br>
I agree, though, that this is probably a bad idea long term. At
minimum, I'd expect scale to build up on the fins and that'll have
a big effect on heat transfer. But even if you're using distilled
water, I'd expect to see increased corrosion where the aluminum
fins contact the copper coils because you're subjecting those
junctions to constant water (more so than normal condensation).<br>
