Ranges include the 186 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 | 15.2–16.5 | 186 / 186 |
| EER2 · BTU/Wh | 11.7–13 | 186 / 186 |
| HSPF2 · BTU/Wh | 7.8–8.5 | 186 / 186 |
| Cooling capacity · BTU/h | 33,800–37,600 | 186 / 186 |
| Heating capacity at 47°F / 8.3°C · BTU/h | 37,200–39,000 | 186 / 186 |
| Heating capacity at 17°F / −8.3°C · BTU/h | 23,000–24,200 | 186 / 186 |
| Heating capacity at 5°F / −15°C · BTU/h | 17,500–19,600 | 186 / 186 |
| COP at 5°F / −15°C | 1.84–2.4 | 186 / 186 |
| Equipment / loop type | HP - Split System | 186 / 186 |
| Refrigerant / source-reported GWP | R-454B (GWP:470 | Lower GWP) | 186 / 186 |
| Compressor staging | Two-stage | 186 / 186 |
| Connected capability | No | 186 / 186 |
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.
