With temperatures dropping into the 30s at night, you've most likely turned on your furnace for the first time this season. If you smell an odor drifting through your home the first few times it clicks on, don't be alarmed. It’s most likely dust that has settled on coils and other heating elements during the spring and summer that needs to burn off, so you should only notice it for a day or two. It might help to open a window or turn on your attic fan to let some of the odor out.
If the smell lingers for longer than a couple of days, it could be something else.
Have you changed your furnace filter? You should change or at least inspect your furnace filter every couple of months to be sure it isn't clogged. Households with pets may want to change the filter more often, as pet dander can quickly clog a furnace.
How long has it been since your air ducts have been cleaned? It’s a good idea to have a heating expert examine your ducts each season. A professional will use high-end, truck-size units to clean out all of the duct work and inspect it for any signs of mold or mildew.
Still smell something? If the smell is still bothering you, give us a call. And if you ever notice a rotten egg or oil smell when your furnace comes on, evacuate your home and call 911, as this can indicate a gas leak.
