I've not used one, but I've not heard anything good about them.


I suspect the main market is folks who live in apartment buildings or condos
that circulates cold water in summer to room air handlers. Some officer
workers may also be targets.

Like it or not, "management's" idea of adequate cooling isn't the same as
many of the tenants. If a tenant can't get management to set the water
chiller to a lower temperature he just hooks up his portable A/C. That's
usually against the rules but it's hard to "catch" folks doing it.
