heat pump question

Long time, no see here but I have a question.

Came across something I have not seen previously. New construction with three heat pumps, the outdoor units all had the form factor you expect for mini splits. However, they were hooked to conventional air handlers and ducting inside. I'm not sure if this is the face of the future, or if somebody did something a little outside of the box. My question has to do with temperature differentials. Should I expect the same temperature differential with these and the "old school" style big boxes outside?

I think there are a couple manufacturers of systems with air handlers paired with "slim" outdoor units.  If you grab the model #s, you can check compatibility.

I've found no difference in operation.  But, it's more likely for the systems with the slim outdoor units to have inverter tech and some have the hyper heat for really cold climates.

What Bill said. 

I see the rather often. As I understand it, their variable speed compressors and variable or multi speed blowers will not always provide the traditional temperature differential.
