Bradbury "soft rains" response

The apocalypse come so Gainesville, pick a room or set of rooms in your home. Describe what electronic processes would continue to occur regardless of human presence. Be very thorough and specific. How long would these processes continue without intervention by humans? Bradbury writes science fiction. Is this piece plausible within our current world situation? Why or why not?

In the living room of my apartment the air conditioner would keep it a nice 75deg. The clock would keep ticking and the fan would be on regardless if there was nobody to turn it off. This may be fine for months but eventually it will get cold outside and the AC will continue to blow cold air and the fan would keep spinning. The first thing to start showing signs of neglect would be the big sliding glass doors. The AC vent blows right on them so when the temperature outside if drastically different the condensation begins to build up. This would eventually turn into mildew and mold and start to soften and rot the frame and wall around it.
I would assume these things would continue until the electricity went off. I think the situation Bradbury proposes seems plausible in the future. We are turning so many things into automated events that can be programed to continue for any given time.  It does remind me of a show that I think was on the discovery? or history? channel for a bit that showed what would happen if all the sudden all the humans were gone. Nature pretty much just took over.
