This 17 year old gas furnace has made this sound at startup for as long as I can remember. At least 10 years if not always.
It only lasts for 2-3 seconds then runs quietly until the next startup.
It does not make this sound in the summer when the A/C comes on. Only the winter heat.
A friend recently heard it and said it shouldn't do that so...any thoughts?
