Most homeowners leave windows open at the wrong times, accidentally pulling hot air in and trapping heat inside. A simple shift in your window routine, timed around outdoor temperatures, can drop indoor temps by 5 degrees or more without touching your thermostat.
Running your AC all night drives up energy bills, but most homes can shed heat naturally once the sun goes down. A smart window-opening strategy combined with simple airflow techniques can drop indoor temps by 10 to 15 degrees overnight without touching your thermostat.
