Goodman heat pump

GSZH506010A*

Ducted split systemTwo-stage

The Goodman GSZH506010A* is a ducted split system heat pump outdoor unit with a rated cooling capacity of 56,500 BTU/h (about 4.5 tons) and a two-stage compressor running on R-410A refrigerant. ENERGY STAR lists 4 certified indoor-unit pairings for it. In cold weather it still delivers 21,600 BTU/h at 5°F — 38% of its 47°F output, below the 76% median across the 308 models we track (better than 1% of them). Its HSPF2 of 7.8 is higher than 6% of models in our database, and its best certified SEER2 of 15.2 beats 6%.

Same equipment sold under other brands

These listings share the same certifying manufacturer (Daikin Comfort Technologies Manufacturing, L.P.) and identical certified capacities and efficiency ratings, so they are almost certainly the same hardware with a different badge. If you get quotes for any of them, you are comparing installation price and warranty, not equipment. How rebadging works.
