Sure, but those amenities are highly visible. Lots of units have a stainless dishwasher exterior, but most will still be the landlord-special plastic tub inside. Who is shopping around based on whether or not there’s a heat pump? I would consider myself relatively well-educated on this and still the heat/cooling source is an afterthought.
Honestly the ductless mini split system in my new apartment was a big factor for me. But it was the first time I'd seen one over here in the mid-atlantic.
