Last month, we debunked a few energy myths that have been out there for some time…myths that could have been costing you valuable energy dollars. This month, in part two of “Stop ‘MYTH’ Understandings…”, we’ll discuss a few more common energy myths and provide the facts so you can save.

MYTH 1: Knocking the chill off.
The term may be a southern thing but “knocking the chill off” a cold room or house by cranking up the thermostat to heat it faster skyrockets your energy bill. An extremely high temperature setting has little effect on how quickly your home heats up. In fact, it may increase your heating system’s run-time, which causes it to use more energy. Programming your thermostat allows you to set temperatures for while you’re away, at home and more. We suggest setting the thermostat at 78degrees Fahrenheit in the summer. Each degree below that increases your cooling costs by about three percent.

MYTH 2: Flipping light switches on and off costs more.
If you’ve been told it’s better to leave the light on than to flip the switch off and on, you can put that myth to rest. There’s some truth to this that stems from the early generations of light bulbs. Turning the lights on and off would decrease the lifespan of the bulbs; however, technology has advanced to the point that this is no longer accurate. It’s best to switch the lights off, even if you’ll be returning in a few minutes. Bottom line… it’s always better to turn “off” the lights when you leave a room.

MYTH 3: Installing a larger HVAC system will be more efficient
Too large an HVAC system will increase energy bills, decrease comfort and shorten the system’s life. A system that’s too big runs in short cycles. Its energy use at start up is the highest, along with the wear on the parts. When choosing a new HVAC system, make sure the contractor does a load calculation for your home using Manual J to determine the precise size it needs to be.
