Furnace heat exchanger

If the OP was showed the crack in the heat exchanger, then its a waste of time to call the gas company. They are just going to kick it back to an HVAC company.

They usually just check for CO and then red tag it or shut it down and tell you to call an HVAC company.

They don't determine what's causing it, just whether its coming from the vents, or flue pipe, or furnace burner compartment, etc, etc.

This was where I was headed. Tough time to get shut down then have scramble to get repaired during busy season and sub zero temps.

Even worse time to die from CO poisoning.

Not a good time for a furnace to go out, I've had some great service with Plumb-line for HVAC issues, good guys.

The furnace works great. I just had it cleaned because we are thinking of selling the house. I purchased a new CO alarm a few days back so now we have 2 in the house.
