Charlotte, N.C. (WJZY) -- With the hot temps, it's nice to be indoors with the A.C. cranked up high. But turning up the air could make your monthly bill go up by 30 to 50 percent according to Duke Energy.
Some of us may turn up the thermostat before we leave for work and turn it back down when we get home. Duke Energy says it can do that for you and save you some money in the process.
"A residential customer can save 32 dollars a year - or 8 dollars a month for a several month period - on their bill they get a credit. That gives us the ability to cycle back their air conditioner from time to time in the summer. Often, they won't notice it's been done," said Tom Williams with Duke Energy.
It looks like a switch connected to your A.C. unit that can turn off the air conditioning for a few minutes every half hour during the afternoon and evening.
"It's a very economical way instead of building a new power plant; we're able to knock off demand off the system. It allows keep power bills low and reduce demand from the system so we don't have to produce as much electricity," said Williams.
That's one way, but others, like NODA resident Lauren Schalburg, are conserving energy and saving money another way.
"We have 17 solar panels on our sun-facing roof. We've had it less than a year so I've been trying to compare bills. We've been saving between 15 and 30 dollars a month," said Schalburg.
Which comes out to 180 to 360 dollars saved a year compared to Duke's program which saves you 32 a year.
Both good options, according to Schalburg, but she says the panels work better for her lifestyle than giving Duke Energy control over her thermostat.
"I wouldn't use it because I work at home during the day. Every time I walk by the thermostat, I think about if I want to adjust it seriously, so I just turn it up if it's not hot," said Schalburg.
