The nearly infinite amount of forum posts about heat pumps dying prematurely and costing thousands and thousands to fix. You don't see how adding complexity on top of complexity in a complex system add points of failures ?

I don't see see a heat pump as complex. It's a compressor, valves and coils. The complexity are the stupid computers foisted onto us.
