Ranges include the 288 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 | 288 / 288 |
| EER2 · BTU/Wh | 12–12.5 | 288 / 288 |
| HSPF2 · BTU/Wh | 7.8–8 | 288 / 288 |
| Cooling capacity · BTU/h | 17,000–18,300 | 288 / 288 |
| Heating capacity at 47°F / 8.3°C · BTU/h | 16,100–17,000 | 288 / 288 |
| Heating capacity at 17°F / −8.3°C · BTU/h | 10,700–11,300 | 288 / 288 |
| Heating capacity at 5°F / −15°C · BTU/h | 8,700–9,100 | 288 / 288 |
| COP at 5°F / −15°C | 2.26–2.34 | 288 / 288 |
| Equipment / loop type | HP - Split System | 288 / 288 |
| Refrigerant / source-reported GWP | R-454B (GWP:470 | Lower GWP) | 288 / 288 |
| Compressor staging | Single stage | 288 / 288 |
| Connected capability | No | 288 / 288 |
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.
