| Reported field | Value / range | Records supplying it |
|---|---|---|
| SEER2 · BTU/Wh | 15.2–18 | 450 / 450 |
| EER2 · BTU/Wh | 10.5–13.5 | 450 / 450 |
| HSPF2 · BTU/Wh | 7.8–9 | 450 / 450 |
| Cooling capacity · BTU/h | 33,400–37,600 | 450 / 450 |
| Heating capacity at 47°F / 8.3°C · BTU/h | 31,800–37,400 | 450 / 450 |
| Heating capacity at 17°F / −8.3°C · BTU/h | 25,200–37,600 | 450 / 450 |
| Heating capacity at 5°F / −15°C · BTU/h | 24,600–26,600 | 450 / 450 |
| COP at 5°F / −15°C | 1.9–2.18 | 450 / 450 |
| Equipment / loop type | HP - Split System | 450 / 450 |
| Refrigerant / source-reported GWP | R-454B (GWP:470 | Lower GWP) | 450 / 450 |
| Compressor staging | Continuously variable | 450 / 450 |
| Connected capability | No | 450 / 450 |
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.
