JANITROL heat pump efficiency: 47 outdoor models compared

JANITROL has 47 heat pump outdoor models certified with this refrigerant group, in 3,377 AHRI-certified combinations. Each model is compared with models of the same size and duct type, so the scores below do not depend on which sizes JANITROL makes. JANITROL has no QMID (IRS Qualified Manufacturer ID) on file, so it is not ranked against other manufacturers.

How JANITROL compares with comparable models

For each rating: the share of same-size, same-type models that a typical model of this manufacturer beats (50% is typical), its rank, and the raw median for context. Raw medians are not comparable across manufacturers that make different sizes.

Top JANITROL 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

No JANITROL model keeps at least 70% of its heat at 5°F with all three cold-climate ratings.

All-around best

Top 5 JANITROL 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.

JANITROL 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.
