MYTH
It's more
efficient to leave the air conditioner running at a minimal
level during the day than to shut it off and have to re-cool the
house again later. |

MYTH
Opening the
registers in all rooms and leaving the interior doors open will
circulate cold air throughout the house more efficiently. |
|
MYTH
To cool off a
house faster, you should crank the thermostat 5-7 degrees cooler
than the desired temperature until the home cools off. |
|
FACT
The less you use the AC, the less electricity you use. When the
AC is running regardless of the level, you are paying for it,
when it is off, you're not. Keep your windows closed while the
AC is off as to not let in additional humidity, a well insulated
home should only drop a few degrees throughout the day while
you're not home. |
FACT
Closing
doors, vents and ductwork to unused rooms makes better and more
efficient use of an air conditioner. Cold air goes where the
heat is. If there is a hot unused room, the air conditioner will
work to cool it off. By closing that room off to the rest of the
house (by register or even more closing the duct work leading to
that room), your home will stay cooler more efficiently. |
FACT
Lowering the
temperature on the thermostat does not make the air conditioner
work any faster when cooling off your home. An air conditioner
extracts the hot air in a home and replaces it with cold. An air
conditioner only replaces a given amount of hot air with cold in
a particular time frame. |
