Paths: 2

Criteria

A model qualifies when one certification meets every value in at least one row.
Path	SEER2	EER2	COP@5°F	Cap. 5/47
DuctedDucted equipment only	≥ 15.2	≥ 10	≥ 1.75	≥ 70%
Non-ductedNon-ducted equipment only	≥ 16	≥ 9	≥ 1.75	≥ 70%

Where the thresholds fall

Every model's representative certification on each rating Xcel CC checks, with its thresholds drawn. A model must clear every line of one path at once, on one certification, so these single-rating views show each hurdle, not the combined pass rate.
