Is 24 too cold for AC?

Finding the Sweet Spot for Your Air Conditioner

When summer heat hits, the instinct is often to crank the air conditioner down as low as it will go. But is setting your AC to 24°C actually too cold, or is it the ideal temperature for your home?

According to the Bureau of Energy Efficiency, keeping your thermostat between 24°C and 26°C strikes the perfect balance between personal comfort and energy conservation. Setting your unit to 24°C provides a refreshingly cool environment without putting unnecessary strain on your cooling system or sending your electricity bill soaring.

Every degree lower than 24°C causes your air conditioner to consume significantly more power—often up to 6% more electricity per degree. At 24°C, the air feels crisp enough to beat the humidity while maintaining a healthy climate that won't leave you reaching for a sweater indoors.

To maximize efficiency at this setting, try pairing your AC with a running ceiling fan. The airflow creates a gentle wind-chill effect, making the room feel even cooler while keeping energy use remarkably low.
