$this->bbcode_second_pass_quote('Johnston', 'I') heard something really disturbing the other day. Apparently, there is an epidemic of the people living in the big McMansions of western Sydney switching their air-conditioners on before they leave for work in the morning, so that they have a nice cool house waiting for them when they get home.
That's leaving the a/c on for 10+ hours, often in 38ºC heat (100ºF). Sheer insanity, just think of the energy bills.
Why can't people use a programmable thermostat? Let the house heat up to 85-90 degrees for the first several hours, THEN lower the temperature in the last hour or two before anyone gets home.
By the way, I leave my air conditioning on in summer during the day while I'm away at work. It's a window unit, so it's not programmable. In my defense, I set the thermostat to 3.5 out of 7, which equates to about 79 degrees. Also, when I go out of town, I either turn the unit off or turn the thermostat way up (to about 2 out of 7 on the dial, which equates to the middle 80s or so). It takes a few hours for the house to cool down if I don't have the air conditioning on during a hot day, so shutting off the air conditioning on a hot summer day isn't really an option.
