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 forgot this is an american centric forum and things are just made cheap/disposable because "it's cheaper'

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.

We don't have a choice. Do you? We're all at the mercy of the manufactures.
Can you offer some evidence of this? I don't see how adding a refrigerant to water heat exchanger after the compressor, before the reversing valve, could possibly hurt the longevity of a system.

Thing with mini-splits is you replace the entire unit so it doesn't matter.
