Central Air -- are there any rules?

as far as i know, there are no rules for central air in NY. as far as temp above 70, that sounds just stupid.

Most buildings with central air have a two-pipe system, where the same set of pipes carries hot water to your units in winter, and then chilled water in summer. In spring and fall the building switches, which raises the problem of when to switch.

Fancy buildings have four-pipe systems, where both hot and chilled water circulates all the time, and you choose hot or cold at your unit.

There's no rule requiring a/c that I'm aware of unless perhaps you live in a modern glass building with fixed windows. If your windows open, there ain't no rule you gotta be cool.

There is no city rule about AC, but some buildings may have dates when they switch their systems.

Thank you for your replies, much appreciated. I called my building and they said central air would be on May 15.

Rules only apply to heat, not AC. And no building should go by dates as to when they turn their system on since there can easily be a hot day or week before May 15.

Just to play Devil's advocate: you should always check:
1) Your lease if you are a renter
2) Your Proprietary Lease and By Laws if you own a Coop, and
3) You By Laws if you own a condo,

because even if the City has no regs requiring it, if you are entitled to something under the agreements you are a party to, you are entitled to it even if there's no law stating that everyone is entitled to it.
