A furnace can sound perfectly normal and still not be safe to leave running.
That's what one of our techs found in a Humboldt home this past year. The furnace itself was an easy fix, a small part swap and it fired back up. But the part that keeps the flame separated from the air moving through the house was worn through with rust, badly enough that the furnace was giving off carbon monoxide, a dangerous odorless gas.
The tech shut the gas to that furnace off right there. Not patched. Off.
Turning it off wasn't the end of the visit, it was the start of doing it right. That furnace came out and was replaced with a new system that could actually be trusted to run safely, not just one that sounded fine.
If your furnace hasn't had a look yet this year, now's a good time to get a tune and clean scheduled before the cold really sets in.
