Mini-split / multi-splitVariable-speed (inverter)ENERGY STAR cold-climateENERGY STAR Most Efficient (some pairings)

The Mitsubishi Electric PUZ-AK30NLHZ*** is a mini-split / multi-split heat pump outdoor unit with a rated cooling capacity of 30,000 BTU/h (about 2.5 tons) and a variable-speed (inverter) compressor running on R-454B refrigerant. ENERGY STAR lists 7 certified indoor-unit pairings for it. In cold weather it still delivers 32,000 BTU/h at 5°F — 89% of its 47°F output, well above the 76% median across the 308 models we track (better than 73% of them). Its HSPF2 of 10.1 is higher than 77% of models in our database, and its best certified SEER2 of 23.8 beats 91%.

Our take in 30 seconds

Best for: cold and very cold climates

Strengths

  • Keeps 89% of its heat at 5°F, so backup heat rarely runs
  • Heating efficiency (HSPF2 10.1) beats 77% of models
  • Cooling efficiency up to SEER2 23.8, better than 91% of models
  • Variable-speed compressor: quieter, steadier temperatures and better humidity control

Good to know

  • Efficiency depends on the indoor unit: SEER2 ranges 17.6–23.8, so ask which pairing you're quoted
