Finding the perfect AC temperature is a balancing act. Set it too high, and you’re sweating. Set it too low, and your energy bills skyrocket. So, what’s the ideal temperature to keep your home comfortable without draining your wallet? Let’s break it down.
The Sweet Spot for Comfort and Savings
According to the U.S. Department of Energy, the magic number is 78°F when you’re home. This setting provides a good mix of comfort and efficiency. But if 78°F feels a little warm, try lowering it by a degree or two and see how you feel. Small adjustments can make a big difference in your comfort and energy costs.
When you’re away from home, bumping up the temperature to around 85°F can help cut down on cooling costs. At night, lowering the thermostat to between 60°F and 67°F can help improve sleep quality.
Smart Ways to Maximize Comfort
If 78°F doesn’t sound cool enough, don’t worry! There are ways to make your home feel cooler without cranking up the AC:
- Use Ceiling Fans – Fans don’t lower the temperature, but they create a wind-chill effect that makes you feel cooler.
- Close the Blinds – Keep blinds or curtains closed during the hottest parts of the day to block out the sun’s heat.
- Limit Heat-Producing Activities – Cooking on the stove, running the dryer, or using the oven can all raise indoor temperatures. Try to do these in the evening when it’s cooler.
- Seal Leaks – Check for gaps around doors and windows. A well-sealed home keeps cool air in and hot air out.
Programmable and Smart Thermostats
Want to save even more? A programmable or smart thermostat can automatically adjust temperatures based on your schedule. For example, it can raise the temp when you’re out and cool things down before you get home. Smart thermostats even learn your habits and adjust settings for maximum efficiency.
Regular Maintenance for Peak Performance
Even if you set the thermostat to the perfect AC temperature, your AC won’t run efficiently if it’s not well-maintained. Keep your system in top shape by:
- Changing the air filter every 1-3 months.
- Scheduling regular tune-ups to keep the system running efficiently.
- Cleaning the outdoor unit to prevent dirt buildup from blocking airflow.
Bottom Line
The best AC temperature for your home depends on your comfort preferences and energy goals. Start with 78°F and adjust as needed. Combine this with smart habits and regular maintenance to keep cool without overpaying for energy.
