Yes, making spare parts and service work is super important. We'll likely set up regional distribution points for spare parts so anything critical can be easily sent next day.
I'm in a temperate climate so there's little actual danger, but the idea of freezing/roasting my butt off for multiple days to wait for parts/labor is deeply unattractive.
My hesitancy is in the ongoing service. I’ve looked into geo-coupled heat pumps but the lack of qualified contractors locally deterred me.
