I don't think air ducts are needed for central heating.
It's much better to have individual AC units than have everyone get long covid because one person in the building was irresponsible
Of course ducts are needed for central heating with the exception of a boiler/radiator system.
You can do PTAC or mini splits to avoid ducts.
Neither of those are central heating.
I mean, I use one evaporator to condition the air on the first floor of my home. I get what you're saying, but a one bedroom apartment could be served by two PTACs.
Perhaps I've lost the thread of this conversation though.
Right, but "central heating" means that the heat is generated in one location then distributed to all other rooms via forced air or steam.
PATCs aren't a form of central heating
Who wouldn't use steam for central heating?
If it's cold enough to warrant central heating, you should probably distribute the heat in steam pipes.
Heat pumps are more efficient
Heat pumps can't create steam?
