I replaced the gas furnace in my central-Ohio home with a heat pump in March of 2024. After a winter which included some very cold days, I am pleased with the performance of my heat pump. This performance depended not only on the heat pump model, but also on climate, house size, and other house characteristics. In the attached pdf article, I share what I have learned about heat pumps after a year’s experience.

Congratulations + thanks for the data-driven writeup!
I replaced my gas furnace with a Bosch heat pump in 2021. I live in the Phoenix, AZ area so the annual low temperature rarely goes below 25 F, so it was an easy sell. Saved some extra money in the last few years, although most of that was in the increased air conditioning efficiency, and the heat pump savings was mostly due to the fact that I have solar panels and there's a surplus of power available in the Feb/Mar timeframe when heat is required.

Most people in Ohio look at you funny when you say you have a heat pump. Some HVAC contractors here are all-in on heat pumps, but others won't even talk to you about them. There are actually some all-electric neighborhoods here that were built in the early 1980's, so that is a built-in market for heat pumps.

Really? Weird. I used to live in Indiana as a child and I remember someone had installed a heat pump.
You guys are lucky, you have soil that you can drill down into for a geothermal (rather than air) heat pump. We have essentially cement; basements are extremely rare because it costs a lot to dig here, and the drainage is poor.
