Smart Thermostat Settings for a Cozy (and Efficient) Winter
October 30, 2025For many homeowners, this winter comes with a key concern: How can I stay warm without my energy bill skyrocketing? If you’ve recently upgraded your system with a smart thermostat—especially after a new HVAC installation in Lancaster, PA—you’re already ahead of the game. However, to make the most of your smart device, it’s essential to know how to use it effectively.
Here’s how to optimize your smart thermostat settings for maximum comfort, efficiency, and savings this winter.
Smart Thermostat Setting Tips to Stay Warm in Winter
1. Understand the Difference Between “Auto” vs. “On”
If your smart thermostat was recently installed, a common setting that can be easily overlooked is the difference between “Auto” and “On.”
- Auto: The fan only runs when the system is actively heating. This setting is more energy-efficient and helps maintain consistent temperature levels.
- On: The fan runs continuously, even when the system isn’t heating. While this can help circulate air and maintain temperature balance, it consumes more energy and may result in higher utility bills.
In winter, use the “Auto” setting to conserve energy while maintaining a comfortable temperature.
2. Follow the Recommended Temperature Settings for Winter
To face the winter climate, the U.S. Department of Energy recommends setting your thermostat to 68°F (20°C) during the day when you’re home and lowering it 7–10 degrees at night or when you’re away. Smart thermostats make this easier by automatically adjusting based on your routine.
Here’s a simple winter schedule to consider:
- 6:00 AM – 9:00 AM: 68°F (wake-up time)
- 9:00 AM – 5:00 PM: 60–62°F (while you’re at work)
- 5:00 PM – 10:00 PM: 68–70°F (evening hours)
- 10:00 PM – 6:00 AM: 60–62°F (overnight)
With smart thermostats, you don’t have to remember to make these changes—they’ll adjust for you.
3. Use Your Smart Thermostats to Reduce Energy Costs
Smart thermostats are more than just programmable devices—they learn your patterns, adjust to weather changes, and even suggest energy-saving settings based on your usage to help reduce your end-of-the-month bill.
Some ways in which smart thermostats help you save money include:
- Adaptive Learning: They adjust to your typical home or away schedule and optimize heating accordingly.
- Energy Reports: Many models provide monthly reports, allowing you to see how small adjustments can lead to significant savings.
- Remote Access: With the app, you can adjust your home’s temperature from anywhere. This can be a lifesaver if you forget to turn down the heat before heading out, or if you want to come home to a warm environment but don’t want to leave the heating on all day long.
4. Take Advantage of Programming Features
Besides the mentioned, smart thermostats come packed with features designed for comfort and savings. Make sure you’re using these top tools:
- Scheduling: Establish a weekly schedule that aligns with your routine.
- Geofencing: This uses your smartphone’s location to adjust the temperature when you leave or return home.
- Zoning Support: If your HVAC system allows it, you can set different temperatures for different areas of the home.
- Weather Tracking: Many smart thermostats adjust settings based on local weather, helping you stay comfortable even during Lancaster’s cold snaps.
