Comment on Would it be better to just have a lot of society be underground?
Bytemeister@lemmy.world 9 hours agoBetter option is to run a heat pump into that underground loop. You really don’t want underground air getting into your house, and a heat pump will let you cool or warm the air using that same underground loop.

I was thinking of a closed loop system not pumping moldy humid air into a house.
Your idea isn’t bad but does need a space big enough for a technician to service the external unit. Also, the external part of a heat pump isn’t supposed to be enclosed. Not sure if a tunnel counts as enclosed or not.

Ground loop heat pumps are already a thing.
As for maintain the unit, you just have a service panel you can remove to access it.
