> Is there a way to get your house (currently with hydronic gas heat) retrofitted for heat pumps that doesn’t result in either a ton of demo or ugly lines all over the exterior?

It's literally the same physical design as an air conditioner. So... yes, unless you hate seeing AC units too, I guess.

A house with hydronic gas heat probably doesn’t have ducts right now. An owner of a house asking how to retrofit a heatpump without a ton of demo increases the likelihood that their house doesn't have ducts.

Adding ducts to an existing house qualifies as a ton of demo in virtually every case.
