A need is a necessity, is AC a necessity or a comfort? It's only a need if without it your life would be so insufferable that you cannot live normally, otherwise it's not a need but a comfort.

Many things aren't needed, survival doesn't mean biological survival so you don't need to bring up "a smartphone isn't a need" since without one a life in modern society becomes quite insufferable (banking access, government access, etc.).

Is AC a need or a comfort to you given this?

Some people live their lives quite ok without a smartphone in Germany, for example - so not a need there either.

I don't like the heat, so need for me - comfort is a need.
