What Should You Set Your Thermostat To In The Summer

Okay, picture this: I'm sprawled on my couch, a melted popsicle stick glued to my hand, trying to decide if I should brave the walk to the freezer for another one. The internal debate is REAL. Suddenly, the phone rings. It's my dad. And the first thing he asks? "Are you running the air conditioner at 68 degrees again?! You're going to bankrupt yourself!" Ah, dads. Always thinking of the bottom line. (And probably secretly judging my popsicle consumption.)
That got me thinking. We all want to be comfortable in the summer, but nobody wants to see their energy bill skyrocket. So, what is the magic number? What temperature setting allows us to achieve peak chill without triggering financial doom? Let's dive in, shall we?
The "Official" Recommendation
Alright, let's start with what the experts – you know, those serious-looking people in lab coats – suggest. The U.S. Department of Energy recommends setting your thermostat to 78°F (26°C) when you're home and need cooling. Now, before you throw your device across the room in protest (I see you!), hear me out.
Must Read
78 degrees might sound unbearably warm. I get it. But the reasoning is actually pretty sound. It's a balance between comfort and energy efficiency. Every degree you lower your thermostat can increase your energy bill by 1-3%. Seriously, those degrees add up! That's money you could be spending on... more popsicles!
And hey, that's just a starting point. Don't be afraid to experiment a little. Maybe 76°F is your sweet spot. Or maybe you're a heat-resistant superhero and can comfortably rock 80°F. Find what works for you.

Factors That Affect Your Ideal Temperature
Here's the thing: there's no one-size-fits-all answer. Your "perfect" temperature depends on a bunch of factors:
- Your Personal Preference: Are you always cold? Do you run hot? This is the most important factor, really.
- Your Home's Insulation: A poorly insulated home will lose cool air faster, making it harder (and more expensive) to maintain a comfortable temperature.
- Local Climate: Are you battling the sweltering humidity of the South, or the dry heat of the desert? This will impact how the temperature feels.
- Activity Level: Are you lounging around reading a book, or running a marathon (inside... somehow)? More activity = more body heat.
- Home Layout: Does your home have multiple floors? Hot air rises, so upstairs might be warmer than downstairs.
Think about these things when you're making your decision. (And maybe write them down on a popsicle stick – just kidding! Mostly.)
What About When You're Away?
This is where things get interesting. When you're not home, you should absolutely adjust your thermostat. The Department of Energy suggests setting it to 85°F (29°C). Or even turning it off completely if the weather allows!

Think of it this way: you're not trying to cool an empty house. You're just preventing excessive heat buildup. Your AC system has to work much harder to cool a house that's been baking in the sun all day than one that's been kept at a slightly higher temperature. So, save yourself some money and crank it up (or off!) when you leave.
Consider a programmable thermostat (or even a smart one!) to automate this process. You can set it to automatically adjust the temperature when you leave for work and then cool down the house before you get home. Hello, future! And hello, lower energy bill!

The Bottom Line: Experiment and Find Your Balance
Ultimately, the best thermostat setting for summer is the one that keeps you comfortable without breaking the bank. Experiment to find what works for you. Play around with the settings, monitor your energy bill, and adjust accordingly.
Don't be afraid to adjust your thermostat throughout the day, either. It's not a set-it-and-forget-it kind of thing. If you're feeling chilly in the evening, nudge it up a degree or two. If you're baking during the afternoon, bring it down a bit.
And hey, maybe my dad was right (don't tell him I said that). Maybe I shouldn't run the AC at 68 degrees all the time. But a girl's gotta have her popsicles! 😉
