Average mini-split performance has improved measurably in the intervening 5 years too (according to measured field data in PNW ductless program), even when the model name/number didn't change.

There were a couple of Goodman guys at my dealer meeting. I asked the split system product manager about the report. We'll see if he ca find anything out from the Daiken side.

Well inquiries to ashrae and Goodman/Daiken bore zero fruit. Those of you who have splits or vrv's could be very helpful if you put a WEL on your equipment.
