For most Denver-area homes, the ideal winter thermostat setting is around 68°F during the day when you’re home and active.
At night or while you’re sleeping, lower the thermostat by 6–8 degrees to save energy. If you’re away for several hours, setting it in the low 60s works well.
During cold snaps, avoid keeping your home below the mid-50s for extended periods, as this can increase the risk of frozen pipes. These winter thermostat settings balance comfort, energy efficiency, and home safety in Denver’s high-elevation, low-humidity climate.
If you prefer a warmer home, make small adjustments first. Many homeowners find that 67–69°F feels comfortable when airflow is balanced and indoor humidity is slightly increase
