In the winter, put on that hoodie and turn your heat down a few degrees so that your heating doesn’t have to work so hard. Likewise, in the summer, wear less cloths or more flowy cloths so your AC doesn’t have to work so hard. By turning your thermostat up in the summer and down in the winter, you can save literally hundreds of dollars a year in utility expenses. Heating and cooling is easily the most expensive thing in your house if you use them constantly. By turning them down (or off when you can), you’ll save a bunch of money.
