You should turn off your air conditioner when the outside temperature is cool enough to keep your home at a comfortable temperature by opening windows.
Optimal Times to Turn Off Your AC
According to the reference, the only time it's truly beneficial to turn off your air conditioner entirely is when the outdoor temperature allows you to keep your home at a moderate temperature by opening your windows. This avoids wasting energy while maintaining a comfortable indoor climate.
Here's a breakdown of situations when it might make sense to turn off your AC:
- When it's cool outside: If the outside temperature is consistently lower than what you’d set your AC to, it's a good time to turn off the AC and open windows.
- Mild weather periods: During spring and fall, when temperatures are mild and pleasant, you likely don’t need AC.
- Nighttime cooling: If the nights are cool, opening windows can provide refreshing air and save on energy costs.
Energy-Saving Tips When Your Home is Unoccupied
It's also important to note that even when you don’t completely turn off your AC, you can save energy when your home is unoccupied. Here are a few strategies:
- Raise the thermostat: When you're away, raise the thermostat to a higher temperature. This prevents the AC from working as hard to maintain a lower temperature.
- Use a programmable thermostat: This allows you to set a schedule so that the AC automatically adjusts when you are away or asleep.
- Smart AC features: Some newer AC units have built-in features that help save energy. Consider these if you are in the market for a new AC.
