When people think about ways to save money on winter energy costs and go green at the same time, bigger investments like energy efficient air conditioners and furnaces come to mind. While appliances pay for themselves in energy savings in only a few years, there are many smaller things the average homeowner can do to help the process along during the winter months. First, there’s a least one basic that bears repeating. A clean furnace filter will help you save money while a dirty one will have you paying more money for less heat. It’s a small investment to buy a new one whenever it’s needed, but that small investment goes a long way to saving you money and prolonging the life of your furnace. Then there are things you can do that don’t have anything directly to do with the furnace but affect it and your energy bills nevertheless. Covering over outlets and switch boxes with the insulating covers you can buy at home improvement stores will do their part in reducing heat loss and a drain on your wallet and furnace both. The chimney can be another area where you’ll lose heat. If you still use it from time to time during the winter months, airtight glass doors at the fireplace are a great way to make the system more efficient. While these can be expensive, a chimney that’s no longer being used on a regular basis can stop siphoning the heat from your house with a chimney balloon installed into the flue. If you go this route, remember to deflate the plug and store it before you use the fireplace.
