Ducted split systemVariable-speed (inverter)ENERGY STAR cold-climateENERGY STAR Most Efficient (some pairings)

The Bosch BOVA-60RTB-M20S is a ducted split system heat pump outdoor unit with a rated cooling capacity of 52,000 BTU/h (about 4.5 tons) and a variable-speed (inverter) compressor running on R-454B refrigerant. ENERGY STAR lists 25 certified indoor-unit pairings for it. In cold weather it still delivers 38,500 BTU/h at 5°F — 70% of its 47°F output, below the 76% median across the 308 models we track (better than 36% of them). Its HSPF2 of 9.5 is higher than 61% of models in our database, and its best certified SEER2 of 18.5 beats 58%.

Same equipment sold under other brands

These listings share the same certifying manufacturer (Bosch Thermotechnology Corporation) 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.
