| Indoor unit | Series | Cooling BTU/h | SEER2 | EER2 | HSPF2 | Heat 47°F | Heat 17°F | Heat 5°F | % of 47°F cap. at 5°F | COP 5°F | Cold climate | Refrigerant | AHRI ref. | ENERGY STAR record |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| ACIQ-09W-HP230C | ACIQ Series | 9,000 | 21.2 | 12.6 | 9.1 | 10,000 | 8,000 | 7,000 | 70% | 2.07 | Yes | R-454B (GWP:470 | Lower GWP) | 216032261 | 3723254 |
"% 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 (9,000 BTU/h ÷ SEER2 21.2) | 425 | $78 |
| Heating (10,000 BTU/h ÷ HSPF2 9.1) | 1,099 | $201 |
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)).
