Everything Worried American said is correct. We have one window unit.
The other two, however, are indoor units and somewhat portable. Same principle only water is poured from a pitcher into the front. They're far better than a fan; not as cooling as a/c.
Best of all, they run on regular house current. Central a/c doesn't and neither do many of the window a/c's. Big difference in utility bill.
We had a swamp cooler in our house for a long time. It was pretty darn effective.
ReplyDeleteThat said, we did just have central heat and cooling installed, but this was because our workspaces were a long way from the swamp cooler and regularly were a toasty 110.
