For example, West SJ and North SJ don't need AC.

Downtown and surrounds, East side .... toss up.

South SJ? It would be tough without it.
It also depends on the house itself. If you live on a shady, tree lined street, that makes a big difference. If where you live is well constructed and well insulated, that matters. If you're on a 2nd or 3rd floor apartment, that makes a difference, too.

Yes, this is a really important point. Our current rental faces west, and there are no trees in the yard. So the afternoon sun - the hottest part of the day - just pounds down on the front of our house. The room we use as a combination dining room/office gets the brunt of it. And it's poorly insulated. That room gets so overheated on summer afternoons that the inside walls are actually hot to the touch. Even with the AC running it's not comfortable to be in that room, and the whole house is warmer than it should be by evening. The house would not be livable without AC. But our neighbors a few doors down and facing the other direction have a big shady tree out front, and I see their windows open all the time.

Bring a compass with you. Don't rent a house with substantial west-facing windows that are unshaded.

A couple of hot weeks in September has always been part of the weather pattern. The last few years have been different; that type of heat later in the season, along with a similar wave in June or so.

The point is that people can grin and bear it for a couple of weeks, and maybe for an additional odd week now and then, without A/C. If the frequency or duration increase, more people will be getting A/C, as some are already doing.

A/C is not *necessary* in San Jose. Depending on several factors (such as how much sun your house/appt gets, and how well it is insulated), it can be a comfort. We only use A/C about 4-5 times a year at our house, when the inside temp goes over 81 (which generally only happens when we have 3 or more 95+ degree days in a row). When we do run the A/C, we generally run it for about 15-20 minutes around 6PM). We could get by without it.

I have relatives and friends in Santa Clara, Mountain View, Campbell, and North and South Jose. None of them ever had A/C and still don't, and all of them have been there since the early 1970's. Once a year they complain about a one or two day event near 95F that they call a heat wave.

AC is a must in San Jose. It gets as hot as Sacramento and Fresno for more than just a few days during the summer. When sacramento or Fresno are in 99-100 San Jose is give or take 3-5 degrees cooler.

Especially if you have an older house where it is not as energy efficient and inferior insulation, the newer house in sacramento and fresno probably stay cooler than those in san jose that are many years old.

North of downtown, you don't need air conditioning. South of downtown, you need air conditioning since it gets too hot often.
