ThinkAir heat pump efficiency: 4 outdoor models compared

ThinkAir has 4 heat pump outdoor models certified with this refrigerant group, in 4 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 ThinkAir makes. ThinkAir has no QMID (IRS Qualified Manufacturer ID) on file, so it is not ranked against other manufacturers.

How ThinkAir 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 ThinkAir 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 ThinkAir model keeps at least 70% of its heat at 5°F with all three cold-climate ratings.

All-around best

No ThinkAir model has all five all-around ratings.

ThinkAir 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.
