The ability to be bidirectional only requires a $20 valve (first result from a search is https://www.amazon.com/Fdit-Conditioning-Reversing-Refrigeration-Maintenance/dp/B07SJ7J7X2 https://www.amazon.com/Fdit-Conditioning-Reversing-Refrigera...). That's not the reason for the cost.
- PaulDavisThe1st 3y agoI don't believe that this is correct. Yes, you need the valve. But at each end you need a device capable of either radiating heat to the atmosphere or absorbing heat from the atmosphere. Although the principles behind both processes are similar, heat pumps & minisplits (the indoor part of the system) are fairly distinct from each other. Others have already mentioned the much greater volume of air that a heat pump typically provides service too, additionally.
