What temp to do set your heat and A/C at?

<p>Forgot to mention we do set for 60 at night during the winter. The 68 is daytime when I work in a home office. Summer stays 78 round the clock but AC is only on when the outside temperature around 90 and it is humid. We like open windows and if the evening temp is into the 70’s we will turn the AC for the night.</p>
