Ranges include the 449 published source records for this model. Values in different rows may describe different configurations. Open an individual record to compare values from the same test configuration.
| Reported field | Value / range | Records supplying it |
|---|---|---|
| SEER2 · BTU/Wh | 15.2–16 | 449 / 449 |
| EER2 · BTU/Wh | 11.7–12 | 449 / 449 |
| HSPF2 · BTU/Wh | 7.8–8.1 | 449 / 449 |
| Cooling capacity · BTU/h | 39,500–42,000 | 449 / 449 |
| Heating capacity at 47°F / 8.3°C · BTU/h | 37,400–41,000 | 449 / 449 |
| Heating capacity at 17°F / −8.3°C · BTU/h | 24,200–26,600 | 449 / 449 |
| Heating capacity at 5°F / −15°C · BTU/h | 18,400–22,600 | 449 / 449 |
| COP at 5°F / −15°C | 1.98–2.42 | 449 / 449 |
| Equipment / loop type | HP - Split System | 449 / 449 |
| Refrigerant / source-reported GWP | R-410A (GWP:2088) | 449 / 449 |
| Compressor staging | Two-stage | 449 / 449 |
| Connected capability | No | 449 / 449 |
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.
