Ducted split systemTwo-stageENERGY STAR cold-climateENERGY STAR Most Efficient (some pairings)

The Trane 5TWR7036A1 is a ducted split system heat pump outdoor unit with a rated cooling capacity of 34,800 BTU/h (about 3 tons) and a two-stage compressor running on R-454B refrigerant. ENERGY STAR lists 468 certified indoor-unit pairings for it. In cold weather it still delivers 24,800 BTU/h at 5°F — 74% of its 47°F output, close to the 76% median across the 308 models we track (better than 45% of them). Its HSPF2 of 9.4 is higher than 51% of models in our database, and its best certified SEER2 of 17.1 beats 35%.

Same equipment sold under other brands

These listings share the same certifying manufacturer (Trane and American Standard Heating and Air Conditioning) 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.
