Have you checked your furnace filter?

If you have not checked your furnace filters for a month or so, or worse since last winter then it's about time that you do so. Any filters that are dirty should be cleaned well (I use soapy water) and any that are past their usage should be replaced immediately.

These filters help control the quality of the warm air entering out homes and protect you from dust related ailments. Also by allowing the furnace to operate at it's best you will find your bills will actually start to drop too!
