/diy/ - Do It Yourself

I was redirected here from /g/, an anon recommended this would be the proper place to ask:
Can somebody please elaborate on what (presumably) archaic heating/cooling unit/system is being shown in picrelated?
It's from a NYC apartment listing and "central air" is mentioned in the specifics. The /g/anon pointed out that this isn't central air, but a floor mounted AC unit.
If that's true I presume that heating as well as cooling is managed by that unit.
Can somebody elaborate on the specifics from the picture alone?
Is it pretty much all electric?
Thanks in advance.
