Heat pump records: the highest value on each rating

The single highest certified rating on each measure, from manufacturers with a QMID on file. These records cross every size, and small units rate higher than large ones, so each card names the size and duct type it comes from; “Best in each size and type” below is the like-for-like view. Every number on a card comes from one AHRI certification; ties go to the lower reference number.
