* In the heating season adjust your thermostat while you are not at home or at night while you are asleep. For each degree you lower your thermostat, you can save approximately 3% on energy consumption. * Close your drapes or blinds at night to keep the heat inside your premises. * During the cold weather heating season, seal all openings such as window air conditioners and chimney dampers. * During all seasons do not block any supply air outlets or return registers with furniture or other objects. * Look for a high-efficiency model when shopping for a new gas heating furnace, the latest models can give you up to 98% efficiency and if you have an old furnace this can really add up into big savings.
