Maybe, but they cost a lot less, with no ducts or concrete pads or
plumbing
or special electrical wiring, and low-cost Chinese and Korean labor, vs
local HVAC criminals. At $69 for 5340 Btu/h at 10.2 EER (Daewoo), a 3-ton
system is $69x36K/5340 = $465.17. And if one breaks, the rest keep
working.


The downside to window shakers-

1) Security...Your home is easily accessed if the burglar simply removes the
unit.

2) Noise...Why do you think they are called "window shakers"?

3) Convenience...Twice a year you'll be humpin' those suckers in and out.

4) Money...I don't make any money from window shakers.
