As the cold weather approaches, now is the time to think about how to save money on your heating bill. Your furnace will run more efficiently if you change/clean your furnace filler. Also, the air will circulate better if you vacuum out your vents and registers. If you are changing out your furnace filter, think about switching to a reusable filter it may cost a little more up front, but it will save you money in the long run and it will be one less thing that goes to the landfill.
