How do these combined heating/AC units work?

I suppose so. Although, since the apartment unit does have several settings, there is a possibility that we can find some kind of flow equilibrium.

But why male models?

A buddy of mine used to live in Weehawken and his apartment building had a central boiler with radiated heat, so tenants had no control at all over the heat. Most of the time he had his windows open to cool off the apartment because the heat never shut off.

When did they gentrify Harlem?

I have the same low, medium, and high and they’re all way too high. If I was handy, I could build a little instrument which changes the low setting on and off intermittently throughout the night and make millions selling this little thingamajiggy throughout the city.
