The Next Heat Pump Frontier? NYC Apartment Windows

New heat pumps easily fit over window sills, meaning they could
replace clunky apartment air-conditioning units.

A bit overpriced, imho, but window-sill heat pump is a new way of
doing it for apartment dwellers.

I've bean counted the cost of different fuels (electric, propane,
oil), and switch from electric to propane when temps get below 0C.

I installed a 24,000 BTU  Mini-Split some six years ago, which is nice
for AC/Heat. 

YMMV....but different geo-locations require different solutions,
depending upon energy cost, equipment cost, and climate.
