Record holders, size class by size class

The highest certified value on each single rating, in each size class. A record is one rating, not an overall verdict; for that, see the cold-climate picks. A record across all sizes would mostly go to the smallest units, so each record here is for one size and type.

Covers heat pumps sold new today (R-454B and R-32 refrigerant). See older R-410A models · Updated
