Every system has its pros and cons - some of which most people don't even think of. Like that catchpan under the refrigerator that collects all the condensation from the evaporator coils? It relies on heat from the condenser coils to evaporate the collected condensation. Not saying that you should ditch the idea just for that, only that it's one of those little things people don't think of.
Anyhow, I wonder how feasible it would be if all heating and cooling systems in a home could be connected to a central heat-exchanger system. The problem with it would be that it would require a self-isolating system of quick disconnects that would make the process of installing a new appliance (say, a refrigerator) a not-so-difficult matter. Otherwise, it would be a more complex process where after hooking up the threaded coolant connections, you must then fill the exchanger loop for that system with coolant. Pricey.
