I don’t know about you but when I think about my furnace I really don’t know much more about it than turning it on and off or changing the temperature. At least that’s how it used to be before my furnace starting making funny noises. I was worried I’d be stuck with no heat in the cold winter months to come so I started looking for Furnace Facts about my particular model. I discovered that I was supposed to service the furnace once a year and do some easy maintenance to make sure it ran better. My furnace was dusty and this was blocking the vent making it hard for the heat to get out. When I cleaned it, everything worked better.
