The cost increase is marginal, but the benefits are enormous.

Modern heat pumps work well down to -20F. If it’s that cold I don’t want to live there.

Hm, doesn't look marginal to me. A heat pump is like 5X-10x more costly and requires quite specialist install. An air conditioning unit is pretty easy to install by normal technicians.

When I shopped heat pumps, the actual unit was about 1.5x the cost of an equivalent air conditioner, and after installation the difference was even less.

It's basically the same exact install.
