A noble goal for sure, I’m right there with you. I’m trying to go carbon free myself. The gas furnace is the last thing for me, and it’s mostly simply because the heat pump just won’t do it up to a certain point. I took the idea that reducing 90% of my emissions was better than not doing anything and staying on it.

I hold to my advice, heat pump will take care of 90% of your HVAC needs, with gas as a backup. Another way of thinking is what happens if there’s a -20 degree day and the power goes out? If anything, a gas furnace is a nice safety backup.

I think this winter my gas furnace has kicked on 3 times total so far, and those were only in the early hours of the morning on incredibly cold days. Everything else? Pure electric.
