The best AC temperature, according to the Department of Energy, is 78°F when you are home during the day.
Understanding Ideal AC Temperature
Setting your air conditioner to the right temperature balances comfort with energy savings. Many people think lower is better, but this isn’t always the case. Here's a breakdown:
Recommended Temperature
- Daytime (When Home): 78°F is the recommended temperature by the Department of Energy.
Why 78°F?
- Energy Efficiency: Lowering the temperature further increases energy consumption significantly.
- Comfort: While it might seem warm, many people find 78°F comfortable, especially when dressed in light clothing.
- Savings: Setting your thermostat higher can lead to substantial savings on your energy bills.
Factors Affecting Comfort
- Humidity: High humidity can make 78°F feel warmer. Dehumidifiers or air conditioners with dehumidifying features can help.
- Air Circulation: Using fans to circulate air can help you feel cooler without lowering the thermostat.
- Clothing: Adjust your clothing to suit the temperature. Lighter, breathable fabrics can make a big difference.
Practical Tips for AC Usage
- Programmable Thermostats: Use a programmable thermostat to adjust the temperature automatically when you are away from home or sleeping.
- Seal Windows and Doors: Prevent cool air from escaping by sealing gaps around windows and doors.
- Regular Maintenance: Clean or replace your AC filters regularly to maintain efficiency.
Other Temperature Considerations
While 78°F is the recommended temperature for daytime, you might want to adjust it slightly for other situations:
- When Away: Set the temperature higher when you're away from home to save energy.
- Nighttime: You might prefer a slightly lower temperature for sleeping, but try to keep it as close to 78°F as is comfortable to avoid unnecessary energy waste.
Conclusion
Setting your AC to 78°F when home during the day is a great way to balance comfort with energy savings. By understanding how other factors like humidity, air circulation, and clothing affect your comfort level, you can optimize your air conditioning usage and reduce your energy bills.
