It’s basically never enforced unless you’re being a nuisance or a minority. It’s just a law so that if someone is being a drunken pest but isn’t otherwise doing anything illegal then the cops still have cause to lock them up until they sober up (aka the drunk tank). It is a law that is intended to be selectively enforced but like most selectively enforced laws, it will be enforced more heavily against certain people.
AC systems are heat pumps so I’m not sure what you mean there.
