Alright, let’s talk about something just about every Southern homeowner has wondered while staring at that thermostat:
“Should I turn my AC off when I leave… or just let it run all day?”
Short answer?
👉 It’s not bad to leave it running, but it might not be the smartest way to stay comfortable or save money.
Let’s break it down the Wally way.
First Things First: Your AC Isn’t Meant to Run Nonstop
Your air conditioner is designed to cycle on and off, not run full blast from sunup to sundown.
When it runs all day long, it can:
- Put extra wear and tear on your system
- Increase your energy bills
- Struggle to keep up if something’s not quite right
Now, does that mean you should shut it off completely when you leave?
Not exactly.
The Big Myth: Turning It Off Saves the Most Money
Seems logical, right? If it’s off, it’s not using energy.
But here’s the catch:
When you turn your AC completely off, your home heats up, a lot. Then when you turn it back on, your system has to work extra hard to cool everything back down.
That can:
- Use just as much (or more) energy
- Put strain on your system
- Take forever to get comfortable again
So What Should You Do?
👉 Set it and forget it… smartly.
The sweet spot is adjusting your thermostat, not shutting your system off.
Here’s what we recommend:
- When you’re home: Keep it comfortable (typically 72–75°F)
- When you’re away: Bump it up about 5–8 degrees
- When you’re sleeping: Adjust for comfort (and maybe save a little more)
This keeps your home from turning into an oven without making your AC work overtime later.
When Running All Day Might Be a Problem
Now, if your AC truly never shuts off, that’s a different story.
That could mean:
- Your system is undersized
- Your home isn’t well insulated
- Your filter is clogged (this one’s super common 👀)
- Or your unit needs maintenance or repair
If your AC runs constantly and still can’t keep up… it’s waving a red flag.
What About Super Hot Southern Days?
Let’s be real, South Carolina summers don’t play around.
On those 95°+ days, it’s normal for your AC to run longer than usual. But it still shouldn’t:
- Run nonstop 24/7
- Struggle to hit your set temperature
- Blow warm or weak air
If it does, it’s time to call in reinforcements.
Easy Ways to Help Your AC Out
Want to keep things cool without overworking your system?
Try this:
- ✅ Change your air filter regularly
- ✅ Keep blinds/curtains closed during the hottest part of the day
- ✅ Seal up air leaks around doors and windows
- ✅ Schedule regular maintenance
A little effort goes a long way.
