To optimize your sleep environment, consider using a programmable thermostat. This allows you to set temperature adjustments throughout the night, ensuring a comfortable sleeping experience without overworking your AC unit.

Should You Adjust Your AC Temperature When You’re Away?

When you’re away from home, adjusting your AC temperature can lead to significant energy savings and enhance the lifespan of your unit. Setting your thermostat to a higher temperature while you’re out is advisable, but how much should you adjust it?

  • Summer Recommendations: A temperature setting of around 78°F is generally considered comfortable when home. However, when you leave, increasing the temperature to about 85°F can prevent excessive energy usage without compromising your comfort when you return.

  • Programmed Thermostats: Utilizing a programmable thermostat can optimize your energy savings. You can set it to start cooling your home shortly before you return, ensuring comfort without unnecessary energy usage.

  • Humidity Control: While raising the temperature during your absence will cut energy costs, be cautious about humidity levels, especially in regions prone to heat. High humidity can create an uncomfortable return and could affect your home’s integrity if left unchecked.
