It’s very normal that your furnace will have a funny smell the first time you turn it on. It can sometimes smell like burning, sometimes a little musty. Don’t get worried, it’s a very normal thing and happens in most homes.
Over the course of the spring and summer, dust has accumulated in and around your heat exchangers, vents and registers. As the furnace gets fired for the first time, that dust gets burned off creating that funky smell.
Not long. If the smell doesn’t go away within a few days of your first usage, it is definitely something to get looked at. Your furnace should feel like you have a fire burning, not smell like it.
