Explore certified heat pump models

Filter every outdoor model in this refrigerant group. Each row’s numbers come from one representative AHRI certification (its best COP at 5°F). Sorting by a rating leaves out models without that rating.

Duct type: “Ducted (incl. mixed)” lists every model with a ducted or a mixed (multi-zone) certification, since a mixed system can serve ducted heads; “Ductless (incl. mixed)” every model with a ductless or a mixed one. The rankings compare mixed pairings with ductless units. Why
