So what do you actually do about it?
The most time-tested strategy is also the simplest, and it costs nothing. As one SF resident put it: "All windows open after 6pm until 8am, then windows shut and curtains drawn all day." This is basically how humans survived before electricity, and it still works. San Francisco's marine layer is your free AC — you just have to let it in at the right time and trap it during the day. Blackout curtains are your best friend here.
Beyond that, the fan game matters. A lot. Box fans in windows pulling cool evening air through the apartment can drop your indoor temp significantly in under an hour. Some folks get creative — one local described rigging up "a fan aimed at me with a humidifier in front of it to create a primitive swamp cooler." Janky? Sure. Effective? Apparently so. SF's low humidity actually makes evaporative cooling surprisingly viable.
Then there's the nuclear option: a portable AC unit. They're ugly. They're loud. They'll bump your PG&E bill. But as another resident confessed, "It's ugly, but it has raised my quality of life during those hot days and it's improved my sleep." Hard to argue with that. Sleep deprivation costs you more than a few extra dollars on your electric bill.
Here's the fiscal conservative take: none of this should be this complicated. The reason most SF buildings lack AC isn't climate — it's decades of building codes, rent control disincentives, and landlords with zero motivation to invest in tenant comfort. When your property is guaranteed to appreciate regardless of amenities, why bother upgrading?
Until the market actually forces better housing stock, you're on your own. Blackout curtains, box fans, and maybe a portable unit you found on sale. Welcome to San Francisco — where you pay Manhattan prices for amenities your cousin in Phoenix would laugh at.
