I’m in a very similar predicament but the temperature where I’m at only go down to the 30s-40s mostly during the winter. I get some rebates where I’m at to replace a furnace so that brings replacement costs to be about equal between furnace and heat pump. I don’t have solar, kw per hour costs are around 13 cents. My AC is non op needing to be replaced (it regularly gets into the 100s for months on end) and my furnace is functioning at 25 years old and no problems, although when it turns on it sounds like a small bomb exploding in my ducts. I have 50% of my house with extremely drafty single pane windows, the other 50% have been replaced. House was made in the 1930s out of brick and appears to be well insulated otherwise though. I am afraid that my overall utility expenses will go up drastically with a heat pump though. Can a heat pump even keep up with a house that loses heat like crazy out of the windows? I seem to get contradicting information from the salespeople, the internet, etc. if anyone has any anecdotal info it would be greatly appreciated
