There's a once-a-summer, or really more of a once-every-few-summers level heat wave rolling through the northeast right now...not something I'd necessarily take into account when buying a house. I grew up in very old unairconditioned house in inland New England, where I don't believe I knew anybody in the 90s/early 2000s who had central a/c, even in a fairly affluent area. From what I've read the models don't expect the region to face major summer heat effects from climate change.
When it's in the high 50s/low 60s evey night, and you have some thoughtful design so the house can be ventilated well with just the windows, the cool night air sticks around well into the next day, a cold shower or a little portable a/c unit can get you through the handful of hot nights each summer.
I live in NYC now, where a/c is necessary most nights in July and August, and find it kind of funny to see New Yorkers buying summer houses in my hometown and immediately spending thousands retrofitting central air. For me one of the great pleasures of going home to visit my family is sleeping with the windows open to the chilly night air!
