Mitsubishi Electric heat pump efficiency: 373 outdoor models compared

Mitsubishi Electric has 373 heat pump outdoor models certified with this refrigerant group, in 1,233 AHRI-certified combinations. They are also sold as AMERICAN STANDARD / MITSUBISHI ELECTRIC, Trane / Mitsubishi Electric. Each model is compared with models of the same size and duct type, so the scores below do not depend on which sizes Mitsubishi Electric makes. Ranks are among manufacturers with a QMID on file and at least 10 scored models.

Mitsubishi Electric in the cold

From NEEP’s cold-climate listings: 185 Mitsubishi Electric models against all 253 listed models.

Mitsubishi Electric capacity and COP from 47°F downNEEP cold-climate listings at maximum capacity · 253 models (2.6% of the catalog) have ratings at 47, 17 and 5°FAt 5°F a typical Mitsubishi Electric model keeps 61% of its 47°F capacity; the typical listed model keeps 62%.

Top Mitsubishi Electric models

Its top five cold-climate picks and its top five all-around models across sizes (both scores compare each model with models of its own size and duct type, so sizes compare), then, on each single rating, the model that beats the largest share of comparable models.

Cold-climate picks

Top 5 Mitsubishi Electric cold-climate picks across sizes. Qualifies when its capacity retention at 5°F (capacity at 5°F as a share of capacity at 47°F) is at least 70% and Capacity retention at 5°F, COP at 5°F, HSPF2 are all rated. Score = the equal-weight mean of its peer percentiles on Capacity retention at 5°F, COP at 5°F, HSPF2 (share of the other models in its peer group it beats, 0–100), all from one certified pairing: in each duct type a model is sold in, its qualifying pairing of that type with the best score; equal scores (one decimal) go to the higher heating capacity at 5°F.

All-around best

Top 5 Mitsubishi Electric models on the all-around score across sizes. Score = 50% heating, the mean of its peer percentiles on COP at 5°F, Capacity retention at 5°F, HSPF2, plus 50% cooling, the mean of its peer percentiles on SEER2 and EER2 (share of the other models in its peer group it beats, 0–100). All five ratings are required; there is no minimum heat kept at 5°F. In each duct type a model is sold in, it is scored on its pairing of that type with the best score; equal scores (one decimal) go to the higher cold-climate score, then the higher heating capacity at 5°F.

Mitsubishi Electric size class by size class: cold-climate and all-around

Its best model on each board in every size and duct type it makes. Both scores are 0–100 against every model of that size class (the line on each bar is 50, the typical model there). Cold-climate picks must keep at least 70% of their heat at 5°F; the all-around score needs all five ratings and has no such bar.
