I don't deal with much of that homeowner shit, just coop owner shit.
But I will mention that in the 16 years we've "owned" this apartment, I'm only on my 2nd fridge. Same brand as the first - well, this is a Kitchen Aid, the previous one was an Amana, but the exact same product with different names. Nary a problem with the first, and so far, so good, on the newer one, which I figured had to happen with our kitchen reno.
My feeling about refrigerators is that they keep shit cold. And if they do that properly, that's all that matters. Ranges, dishwashers - that's a whole other story.
As far as air conditioners go...we only have window units. And in those same 16 years, I've probably had at least a dozen different air conditioners between the bedroom and the living "area." Basically, all pieces of shit, and I should've kept the first one I ever had, an old school Freidrich.
