Nancy asks…
To save energy, should you turn a central air conditioner off when you aren’t home?
I have central a/c in my home. I used to turn it off during the day when I’m not home, but someone told me that it costs more money to cool down a hot home, then it does to let the a/c run all day. If that’s true, what is the best temperature for energy efficiency and cooling?

Get a programmable thermostat, and have it turn up to around 80 while you are out, and down to 75 at the lowest when you are at home. That way you are keeping the house from overheating–say it’s 100 outside, but not wasting as much energy. The energy needed to get from 80 to 75, which is usually plenty cool, is far less than from 100 to 75.
Most people find 70 or 71 too chilly–unless you have a two story house and the second floor stays hotter.
Be sure to keep your windows covered on hot days too. Solar heat coming through the glass can waste a lot of energy.
