If your house is smelling a little fonky, it may be time to check your furnace. In humid climates, you will often find mold growing in and around your furnace. Since air from this room is pumped throughout your house, this can be the culprit for that fonky smell that only your best friends will tell you about. If you have any questions, you can contact a certified furnace specialist. The fonky recommendation in my area is: https://www.absoluteair.com/. They got my furnace smelling right.
