That's a great point. It looks so sleek in the ad, but then I'd also have to somehow get new window screens that work with it, plus the poor seal and who knows how many other minor irritations.

Why This Window Heat Pump Is Genius

I suspect they'll come down a lot in a few years to at least make the energy+unit cost competitive with window AC units.

I'm not sure I'll ever love window units though. They tend to break the window's air/noise seal (which is already weak especially with the cheap construction going on in Austin these days), and as someone sensitive to noise, I'll usually avoid them.
