No matter what part of the country you live in, you are always going to need either heating or cooling. Or like me, both. Some heating and air conditioning units can be terrible energy hogs.
1. Make sure all windows are closed up tight when running your heat or air. The last thing you want to do when paying for temperature control is to have it all go out the window!
2. In the summer, try sheer curtains, blinds or solar shades to keep the sun from warming up your room. There is also a tinted window film that you can put on your storm door or windows, too.
