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

The ACiQ B5H3V60*K*AAA* is a ducted split system heat pump outdoor unit with a rated cooling capacity of 58,000 BTU/h (about 5 tons) and a variable-speed (inverter) compressor running on R-454B refrigerant. ENERGY STAR lists 32 certified indoor-unit pairings for it. In cold weather it still delivers 47,500 BTU/h at 5°F — 78% of its 47°F output, above the 76% median across the 308 models we track (better than 54% of them). Its HSPF2 of 9 is higher than 47% of models in our database, and its best certified SEER2 of 20 beats 72%.

Our take in 30 seconds

Best for: mixed climates with occasional hard freezes

Strengths

  • Cooling efficiency up to SEER2 20, better than 72% of models
  • Variable-speed compressor: quieter, steadier temperatures and better humidity control
  • Uses newer, lower-impact R-454B refrigerant
  • Also sold under 8 other badges, so you can compare more quotes for the same unit

Good to know

  • No notable drawbacks in the certified data.
