I’m surprised you needed AC at 10k ft. I have a cabin south of FairPlay at 9200 ft and the high temperature for the year has never exceeded 81 F.

Good to hear on the heat pumps though. I’m planning to eventually replace the propane boiler with them.

So the home is southern facing and was full of windows on the southern side. So even with windows open/shades down the heat from the sun would still radiate in.

When I bought the home I had a company come to help me plan the heating and I don't fully understand the science but the home is built to keep heat in with the windows and no attic.
