The problem are large building air conditioning systems, grocery store chillers and industrial machines - they contain an awful lot of coolant and are very expensive to replace which means they tend to last for decades.
I don’t know how popular these are. I have seen multiple condo buildings with a water source heat pump in each unit. The usual suspects (Mitsubishi, Daikin, etc) have hydronic systems with outdoor heat pumps on their websites. Chiltrix markets a small-building solution.
