Do your electricity bills skyrocket during the hot summer months?
If so, you might be tempted to turn off the air conditioning when you leave the house, but energy experts warn that doing so could do more harm than good.
When you’re leaving the house for a day of work or errands, you don’t have to turn off the air conditioner to conserve energy, according to How Stuff Works.
Instead, just adjust the temperature on the air conditioner, cranking it up to just a few degrees above the setting you normally leave on at home.
If you have central air conditioning or a standalone unit, this adjustment can save you energy and money without making the house too warm when you get home.
“Turning off the air conditioning during the day isn’t necessarily a bad thing,” the experts said. “It’s a myth that the air conditioner has to work extra hard to cool a hot house.”
But during a heat wave or high summer temperatures, it can take several hours for your home to cool down after the air conditioner has been off all day.
This is especially true if you live in a humid place. Your air conditioner works to reduce the humidity in your home and you need to take care of that.
“If the system is shut down for more than a few hours, humidity levels will begin to rise, which can lead to mold growth, damage to electronic equipment, and warping of wood and paper,” the experts warn.
That’s why you should leave the air conditioning on – even if you’re going away for the weekend. So when is turning off the cooling system the right choice?
According to Logan Kureczka, chief communications consultant at Duke Energy in North Carolina, you should turn off your air conditioning if you’re going away for more than two days.
Kureczka told How Stuff Works that turning off the air conditioner for two full days will have the biggest impact on your energy savings.
“You’ll save the most energy — and your bill — by turning off your device,” Kureczka explained.
On weekdays or weekends, turning the air conditioner to a higher temperature and closing all the curtains should be enough to keep the house cool without wasting energy or money.
“As a rule, a temperature increase of just two degrees helps to reduce cooling costs by five percent,” says Kureczka.
Running the ceiling fan won’t do much — as Kureczka said, fans have a cooling effect on people in the room, but they don’t change the temperature, so they won’t help if you’re not home.
And if you travel frequently, especially during the summer months, you could benefit from a remote control thermostat.
“Investing in a programmable or smart thermostat is a great way to monitor and control the energy efficiency of your home even when you’re not there,” added Kureczka.
“You can turn on the thermostat before leaving and then start cooling down on the way home.”
