What can I do outdoors to save in the winter?

What can I do outdoors to save in the winter? 

Clean your windows and open drapes to let sunlight naturally warm your home during the day. Sweep your chimney by hiring a professional to ensure it’s clean, safe and ready for use during colder months. 

Switch to LED holiday lights — they’re more energy efficient, longer lasting and safer than incandescent lights. Be sure to take down both indoor and outdoor holiday lights once the season ends to avoid unnecessary energy use. 

Keep leaves and debris away from HVAC units to maintain efficiency and airflow. Avoid using emergency or auxiliary heat modes unless absolutely necessary, as they consume significantly more energy.
