Light bulbs are hot!

Breaking news: Light bulbs are hot.   What's the big deal? When it's as hot as it's been, simply keeping the lights off can make it cooler.  Yes, the a/c can overcome their heat, but ceiling lights can make you feel hot just because you're closer to them and their heat has not yet affected the thermostat.

Beeping smoke detectors

You know it's a common problem when a TV show has it as part of the storyline.  "Modern Family' had the chirping smoke detectors and how it drives people crazy.  We don't recommend hitting them with a bat to stop the noise.  (They should all be replaced every 10 years.)
