> If so, that would be why. A lot of places here get quite cold. Heat pumps in Alaska: * https://www.adn.com/business-economy/energy/2024/09/01/energ... However, before spending money on new mechanical units, it's usually better to improve insulation and air tightness first: there's no sense heating (or cooling) and then have the conditioned air leak in/out of the house. Further, there are hybrid / dual-fuel systems:…
I lived in Alaska and am there a few months every year. You actually don't want insane insulation. Alaska is wet, and if you trap condensation and add heat for warmth, you get mold.
Yes, you do want high insulation, and also good air tightness.

You want a very good building envelope and you control inside conditions through mechanical means. You control condensation dehumidifiers.
