If your intention is to heat or cool air using as little electricity as possible, a basic split air conditioning unit is going to be more than adequate for 90% of people. If you live in Yakutia, then yeah you probably need to look into something else, but for the vast majority of people it’s going to be fine. A general recommendation doesn’t mean it’s the best choice for literally every single person.

But it very often catches many who simply take it as an irrefutable truth.
As I gave as an example, my one Daughter who is recognized by her peers as an expert in this field, and is all about improved efficiency and renewable energy, did the math and found that it doesn’t work for her. And it’s not because she lives in a terrible climate - it’s warmer and varies less than where I live by a noticeable amount. It’s because when you compare total costs, over the life span of a heat pump, she would end up paying extra to have one verses a simple natural gas furnace. It would be even sillier for my neighbor who is a logger. He uses 100% wood heat. Because he can literally harvest, process, and store enough firewood for several years in one afternoon. Anything else is far more expensive. But the math says it works for me.
You can’t make general statements about 90% of all people until everyone does the math. This is just one of the field studies my Daughter is doing. Trying to collect enough real time data on real homes and families and doing the math to help pinpoint locations where it makes sense and where it does not make sense at this time. It does not always workout like you and I might think it would.
