I live in Phoenix, don’t have AC and don’t want it. But to be fair, that is a complex decision. And not one for everybody as prior AC zealots have posted in the other manner. Why don’t I want it?
While it may be blisteringly hot in PHX, it is usually dry (like Las Vegas). I dread humidity and probably would strongly reconsider if I lived in a more humid environment. I could be convinced if I lived in Miami.
We have high MEA’s, so other than cross town trips I usually go fairly high. Certainly higher than you do in Florida. Result, comfortable temps reasonably quickly.
It is miserable to fly in the afternoon in the summertime, regardless of cabin temps. Thermals! So I don’t very often. I just plan my trips around that fact. No installed AC system would change that.
All weight permently installed in an aircraft is bad for useful load and performance reasons and needs to be seriously considered. When I looked at adding AC many years ago it moved my plane from being a full fuel family aircraft to something less. At the time I had 2 teen kids living at home and could load all of the fam, full fuel and small bags. I will compare my svelte 2241 empty weight any day with more portly variants. I can haul more, but when I don’t use that load I climb and cruise faster. That is a permanent performance penalty. One some are happy to give up, I do so less willingly.
Mx hassles are not trivial. Even changing oil on an AC bird is a PITA.
So Wally, I do not consider myself “tough”. I prefer smart, prudent or some other term [;)] but seriously it is more of a mission, location and personal values sort of thing. In the end, we all choose our options with our mission, our values and finances in mind.
I think giving universal advice like don’t get one without xxxx (fill in your option, AC, Perspective, FIKI, etc…) is simply putting our values on someone else’s decision and we don’t know their values or mission.
