What temperature should I set my thermostat to?

Pick a comfortable occupied setpoint and save by setting back while asleep or away. Consistency and scheduling matter more than the exact number.

Savings come from reduced run time, which is produced by setback periods rather than by a heroic occupied setting. A modest setback for eight hours a day generally outperforms a small permanent change.

Heat pumps behave differently. Deep setbacks can trigger auxiliary electric heat during recovery, which can cost more than it saves. Use a smaller setback or a control designed for heat pump recovery.

What to check first

  • Whether your system is a heat pump, and how it handles recovery
  • That the schedule matches when the home is actually occupied
  • That the thermostat is not mounted in direct sun or near a supply register
  • Whether humidity, not temperature, is driving discomfort in summer

When to call a professional

  • The measured room temperature differs substantially from the thermostat reading
  • The system cannot maintain setpoint in normal conditions
