Hiya,
Well I'm considering biting the bullet and changing out my swamp cooler for
a refrigeration unit.
Before I even bother with getting quotes, one question keeps nagging at me.
Do these units use
recirculated air from the house or are they pulling all the air from the
outside? If they recirc, then
I might as well not bother as there's really no viable (monetarily and
aesthetically) way to add a
return air duct to it. It's clear I don't have a good understanding of how
these units work (I've been
in swamp cooler land for 25 years!). Just curious.
Thanks much,
jlc


Do you have forced air heat system ?? If so, the AC fits within it and
use same existing ducting. Yes, it recirculates inside air, otherwise
would run continously and cost a fortune to operate. You normally close
all doors and windows, which can be its own problem re "stale" air etc.
I've had both systems; if swamper has been OK (ie dry climate like
Denver), you won't like AC.
