What temperature should you set your Air Conditioning to in Summer?

The ideal temperature setting for air conditioning in the summer largely depends on personal preferences and the desired balance between comfort and energy efficiency. However, some general recommendations can be followed:

1. Energy Efficiency: The U.S. Department of Energy recommends setting your air conditioner at 78°F when you’re home and awake and raising the temperature while you’re away from home or asleep. This setting is considered a good balance between comfort and energy efficiency during the hotter months.
2. Personal Comfort: Everyone’s comfort level is different. You may find that 78°F is too warm, or perhaps it’s just right. Adjust the temperature to find a comfortable setting for you and your family. Remember that for every degree you raise the set temperature, you can save significantly on cooling costs.
3. St. Louis, Missouri Climate: Summers in St. Louis can be hot and humid. The high humidity can make it feel warmer than the actual temperature. If you find it uncomfortable, consider using a dehumidifier alongside the air conditioner. A lower humidity level can make a higher temperature setting feel more comfortable.
4. Ceiling Fans: Using ceiling fans with your AC can make the room feel more relaxed even when the thermostat is set to a higher temperature. Just remember to turn off fans in rooms that aren’t being used, as fans cool people, not rooms.
5. Heat Reduction: Consider other ways to keep your home cool, like using blinds or curtains to block out sunlight, ensuring your home is well-insulated, or planting shade trees.
6. Regular Maintenance: Ensure your AC unit is serviced regularly and its filters are cleaned or replaced as needed. A well-maintained unit will work more efficiently and can cool your home at a lower cost.

Ultimately, the right temperature setting for your air conditioner in the summer in St. Louis, Missouri, will depend on your personal preferences, how well your home retains cool air, and any energy efficiency goals you might have. Adjust and find a temperature that meets your comfort and efficiency needs.
