How to cut the cost
- Set the target temperature (for example 68°F) instead of the maximum; the unit cycles heat off once reached.
- Use Focused mode toward you rather than Diffused mode to warm yourself with a lower room temperature.
- Use the sleep timer (30 minutes to 8 hours) at night.
- In purifier models, keep heat off and run only fan mode in shoulder seasons; it costs about 1/40th as much.
