Before it gets chilly outside, take a moment to walk around the house and inspect all the heater vents in your home. Make sure none of them are blocked or closed. That may sound simple and silly, but these things can happen over the course of the year, when people move furniture or accidentally bump a vent closed while vacuuming. Make sure there's ample room around the vent to allow for maximum efficiency when you do need to keep the chill out of the room this winter.
