I have tried searching for past problems. We need help in figuring out if we need to call a heating specialist or try to figure this out. We have electric heating forced air. There is like a stinky pee smell coming from our furnace and through the bathroom vent (which is closest to the furnace, but the smell is strongest from the furnace. It is about 8 years old. Central Electric Furnace, Standard Blend Air II. Any suggestions? We appreciate your help.
