Smart thermostat

Nests work great if you have the wiring, and it really does take just a few minutes to install. If you go to their website, they will probably have an easy diagram that you can compare to your current wires.

I would be concerned about a 40 yo furnace on the reliability front. Your problem is that failure is VERY expensive if you do not have backup and/or repair before your insulation can no longer hold back the cold. And of course, you also need an alarm to warn you when furnace has failed.

Now might be a good time to replace furnace, or even better get heat pumps. Deals available from NHEC, and maybe from Build Back Better if it passes
