Thermostat Settings and Heating Efficiency Tips

Your thermostat is one of the simplest—and most powerful—tools for controlling home energy costs. The U.S. Department of Energy recommends setting your thermostat to 68°F when you’re awake and home, and lowering it to around 60°F when you’re sleeping or away. These small adjustments can significantly reduce heating demand without sacrificing comfort, especially during New Jersey’s long heating season.

Smart thermostats take this a step further by automatically adjusting temperatures based on your schedule. In many NJ homes, they can pay for themselves in under two years through reduced energy use. Instead of manually adjusting temperatures, you can create setback schedules that optimize efficiency while keeping your home comfortable when you need it.

Without proper thermostat management, homes often waste energy heating empty spaces or maintaining unnecessarily high temperatures. Skipping these adjustments can lead to higher utility bills and unnecessary strain on your heating system. With a few simple changes, you can improve comfort, reduce costs, and extend the life of your HVAC equipment.

Step-by-Step Guide

1. Set Baseline Temperature

  • Set to 68°F when home and awake

  • Comfortable balance between warmth and efficiency

  • Adjust slightly based on preference

2. Program Setback Temperatures

  • Lower to ~60°F when sleeping or away

  • Saves energy during low-use periods

  • Avoid extreme swings that strain the system

3. Create a Daily Schedule

  • Morning: increase temperature before waking

  • Daytime: lower when home is empty

  • Evening: raise for comfort

  • Night: reduce again for sleeping

4. Install or Upgrade to a Smart Thermostat

  • Automates temperature adjustments

  • Learns habits and optimizes efficiency

  • Allows remote control via mobile app

5. Avoid Constant Manual Adjustments

  • Let programmed schedule manage temperatures

  • Frequent changes reduce efficiency

  • Consistency improves performance

6. Check Thermostat Placement

  • Ensure it’s not near drafts, sunlight, or heat sources

  • Improper placement can cause inaccurate readings

  • Affects system performance

7. Monitor Energy Usage

  • Track heating bills and adjust settings if needed

  • Look for patterns in energy consumption

  • Optimize over time
