We need to figure out how to retrofit those old machines to be as efficient as the new ones, and be clean and pigeon free. Then we can keep them around.
Is there any reason a window unit couldn’t be a heat pump? My understanding is the difference is just about a single valve to reverse the direction of the coolant.

They still make those old style ones and they are energy star certified.
The ones that look like the new one are what’s used with heat pumps here.

From my understanding is a heat pump needs to be fully outside of the house.
Uhh, old style is heat pump too. Unlesz you are referring water evaporation.
