It’s the age-old pre-vacation debate. You’ve packed the suitcases, watered the plants, and locked the back door. Now you’re standing at the thermostat with your finger hovering over the “Off” button, wondering: Am I just throwing money away by cooling an empty house, or should I turn it off? And honestly, it’s a fair question. Logic says “save energy,” but your home’s ecosystem says “not so fast.”
Here is the breakdown of why hitting “Off” is actually a bad move, and what you should do instead to save money without coming home to a swamp.
1. The Humidity
Your AC isn’t just a “cold air maker” – it’s a massive dehumidifier. In many climates, the humidity is a bigger threat than the heat. If you turn the system completely off for a week in the summer, moisture builds up inside your drywall, flooring, and furniture. The risk? You could return to a home that smells like an old basement, or worse, find mold growth on your baseboards and inside your closets.
2. The Added Cost
If you turn the AC off and your house hits 90°F inside, every single thing in your home – the couch, the carpet, the walls – soaks up that heat. When you finally get home and crank the AC back down to 70°F, the unit has to work at maximum capacity for hours (or even a full day) just to remove the “heat load” stored in your furniture. This puts massive strain on the system and often negates the energy you saved while you were gone.
3. The Damage to Your Electronics (and Pets)!
High heat is the enemy of modern technology. If your home regularly climbs above 85°F, it can shorten the lifespan of your TV, gaming consoles, and even your refrigerator (which has to work twice as hard in a hot kitchen). Plus, if you have indoor plants or – more importantly – fish or small pets, a “turned off” AC can be a literal death sentence.
So, What Should I Do Then?
So, what’s the move? Don’t turn it off – just turn it up. A good rule of thumb is to set your thermostat about 4 to 7 degrees higher than your usual “at home” temperature, but never higher than 80°F–82°F.
Why 82°F? We’re glad you asked! This is generally considered the threshold where humidity starts to win. Keeping it at 82°F ensures the air stays moving and the moisture stays out, but your electric bill stays low.
The Smart Thermostat Advantage
If you have a smart thermostat (like a Nest or Ecobee), use the “Vacation Mode.” This allows the system to run just enough to keep the air from stagnating, and you can even “wake up” the house from your phone while you’re at the airport heading home.
The Verdict
Don’t kill the power. Leave the AC on, bump the temperature up to the low 80s, and close your blinds or curtains to keep the sun from “baking” the interior. You’ll save money, protect your home, and – most importantly – you won’t walk into a sauna the second you get back.
