It’s common knowledge that a programmable thermostat is a smart investment to regulate temperatures in your home and keep your heating and cooling bills as low as possible. In the hot summer months, when you’re away during the day, set your thermostat to what the average high temperature will be for the day. When the difference between your indoor and outdoor temperature is small, it allows your HVAC system to work as efficiently as possible. So while the morning temps are cool, check to see what the average high is and set your thermostat for that temperature.
