Myth (noun) \ ˈmith  \ — A widely held but false belief or idea.

Check out these myths associated with energy efficiency.

MYTH #1
When I’m not home, keeping my air conditioner at a lower temperature throughout the day means it doesn’t have to run harder to cool my home when I return.
FACT
To save energy, set your thermostat to a higher temperature during the day, and lower it when you return home.


MYTH #2
Closing vents on my central air conditioning system will boost efficiency.
FACT
Closing vents can cause the compressor to cycle too frequently and the heat pump to overload. You’ll also use more energy.


MYTH #3
Turning appliances off eliminates their energy use.
FACT
While turning your appliances off will help cut their energy use, electricity is still drawn from appliances that are left plugged in. This process is referred to as a “phantom” load. Consider plugging your appliances and electronic equipment into a smart power strip that requires a single switch to power all of them on and off and a single adapter to unplug them all.


MYTH #4
Ceiling fans can help cool a room.
FACT
Ceiling fans simply circulate air throughout a room to make your skin feel cooler. Fans do not cool the air, they just cool people. Using a ceiling fan may allow you to raise that thermostat, but leaving one running in an unoccupied room will simply waste energy.


MYTH #5
Bigger is always better when it comes to cooling equipment.
FACT
Too often, cooling equipment isn’t sized properly and leads to higher electric bills. A unit that’s too large for your home will not cool evenly and might produce higher humidity indoors.
