Winter Heating:
1. Close fireplace dampers when not in use. Do not use your fireplace and central heating unit at the same time. Interior heated air can be sucked up through your chimney.
2. Know 3 to 5 percent more energy is used for each degree that your...
... furnace is set above 68 degrees
... A/C is set below 78 degrees.
3. Open window shades and drapes to help warm rooms during the day, and close them to keep warmth in at night.
