| Reported field | Value / range | Records supplying it |
|---|---|---|
| SEER2 · BTU/Wh | 15.2–21 | 174 / 174 |
| EER2 · BTU/Wh | 11.2–13.5 | 174 / 174 |
| HSPF2 · BTU/Wh | 8.1–10.2 | 174 / 174 |
| Cooling capacity · BTU/h | 21,600–24,000 | 174 / 174 |
| Heating capacity at 47°F / 8.3°C · BTU/h | 23,600–27,400 | 174 / 174 |
| Heating capacity at 17°F / −8.3°C · BTU/h | 18,700–22,400 | 174 / 174 |
| Heating capacity at 5°F / −15°C · BTU/h | 13,900–18,600 | 174 / 174 |
| COP at 5°F / −15°C | 1.7–2.3 | 174 / 174 |
| Equipment / loop type | HP - Split System | 174 / 174 |
| Refrigerant / source-reported GWP | R-454B (GWP:470 | Lower GWP) | 174 / 174 |
| Compressor staging | Continuously variable | 174 / 174 |
| Connected capability | No | 174 / 174 |
47°F = 8.3°C; 17°F = −8.3°C; 5°F = −15°C. COP is dimensionless. These are reported rating points, not a prediction of a particular home’s heat demand or operating limit.
Matched systems
Each row is one source record. The component column distinguishes listed combinations from outdoor-model ratings without an indoor configuration.
