"% of 47°F capacity at 5°F" = heating capacity at 5°F ÷ heating capacity at 47°F, both from the ENERGY STAR record (ENERGY STAR's cold-climate designation requires ≥70% and COP ≥1.75 at 5°F; criteria).
Rough running-cost yardstick (top-rated pairing)
| kWh per 1,000 full-load hours | Cost at U.S. avg rate | |
|---|---|---|
| Cooling (24,000 BTU/h ÷ SEER2 20.5) | 1,171 | $214 |
| Heating (25,000 BTU/h ÷ HSPF2 11.5) | 2,174 | $398 |
Cost estimates: cooling kWh ≈ cooling capacity × full-load hours ÷ SEER2 ÷ 1,000; heating kWh ≈ 47°F heating capacity × full-load hours ÷ HSPF2 ÷ 1,000. "Per 1,000 full-load hours" is a yardstick for comparing systems, not a prediction of your bill; your hours depend on climate, house and settings. Rate: U.S. average residential 18.31¢/kWh (EIA, July 2026 (preliminary)).
