| 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 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Multi-spilt series | 36,000 | 22.75 | 12.5 | 10.5 | 36,000 | 33,400 | 33,400 | 93% | 1.95 | Yes | R-32 (GWP:675 | Lower GWP) | 217751661 | 4572997 |
"% 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 (36,000 BTU/h ÷ SEER2 22.75) | 1,582 | $290 |
| Heating (36,000 BTU/h ÷ HSPF2 10.5) | 3,429 | $628 |
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)).
