- Babies have sensitive temperature needs and need a bit warmer environment to avoid chilling. 23-25°C (73-77°F) is a great level for them.
- Seniors tend to feel cooler and may benefit from a slightly warmer indoor temperature. They are usually okay at 23-26°C (73-79°F).
- For most adults, the best temperature is between 24 and 26°C during the day. It’s comfortable for rest and work and does not skyrocket energy costs.

What should I set my AC to at nighttime?
Your bedroom temperature impacts your sleep, even if you do not notice it. An indoor temperature of around 18°C (65°F) helps the body prepare for sleep. A bit cooler environment is good for deeper sleep stages, including REM, which is essential for rest and memory retention. If your bedroom is warmer than 21°C (70°F), your sleep gets lighter, less restorative sleep and you may awaken from time to time.
If you prefer a slightly warmer room, setting the AC between 15-19°C (60°F – 67°F) is still acceptable as it encourages a consistent, uninterrupted sleep cycle.
Energy-saving tips for a cooler house in summer
Knowing the best temperature for AC in summer does not help you solve growing energy bills. Luckily, there are some practical tips to let you make the most of your air conditioning and control your utility expenses.

- Regular maintenance. Don’t leave your AC unit to chance! Timely service checks will help it work efficiently. Also, regularly clean your AC and replace filters to ensure optimal airflow and performance.

Additional ways to keep your home temperature comfortable.
Your home temperature does not depend solely on the AC! Instead of cracking your air conditioner, use these simple tips to make your home cooler in summer:
Use natural ventilation
During cooler times of the day—like early mornings and late evenings—just open windows and doors. It will allow fresh air to flow through your home and make it feel more inviting and less reliant on your AC.
Use dehumidifiers
High humidity can make warm air feel even hotter. A dehumidifier helps lower humidity levels and create a more comfortable environment. Dehumidifiers come in two main types: compact, portable units for individual rooms and larger, whole-house models for widespread moisture control.
Check your insulation
Good insulation keeps heat from getting into your home in summer. Take a moment to inspect your insulation, especially in attics and basements, to ensure it’s doing its job well.
Seal air leaks
Make sure there are no gaps around windows, doors, and electrical outlets. If found, use weatherstripping and caulking to seal these air leaks. It can significantly improve your home’s energy efficiency and block hot air from outside.
Use fans wisely
Ceiling and portable fans can circulate air and create a wind-chill effect. These plain devices will let you feel cooler without the overuse of your air conditioner.
Block the sun
Draw the curtains or blinds to keep your home shaded on the hottest days. This small change can help block out unwanted heat and keep your indoor spaces more comfortable. You can use special blackout curtains to maximize the effect.
Cook smart
Do not use the oven when temperatures are incredibly high. Instead, opt for microwave meals or use a slow cooker. This will also simplify your meal preparation.
Consider window tints
Consider tinting your windows. Modern films block out a significant amount of solar heat and harmful UV rays. They help keep your interiors cooler and also protect your furniture from sun damage.
