Heating performance & equipment details
Ranges include the 6 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 | 18.8–21.2 | 6 / 6 |
| EER2 · BTU/Wh | 12–13 | 6 / 6 |
| HSPF2 · BTU/Wh | 10–13.5 | 6 / 6 |
| Cooling capacity · BTU/h | 22,000–24,000 | 6 / 6 |
| Heating capacity at 47°F / 8.3°C · BTU/h | 25,000–29,000 | 6 / 6 |
| Heating capacity at 17°F / −8.3°C · BTU/h | 16,900–22,200 | 6 / 6 |
| Heating capacity at 5°F / −15°C · BTU/h | 23,600–24,200 | 6 / 6 |
| COP at 5°F / −15°C | 2.16–2.34 | 6 / 6 |
| Equipment / loop type | HP - Mini or Multi Split · HP - Split System | 6 / 6 |
| Refrigerant / source-reported GWP | R-454B (GWP:470 | Lower GWP) | 6 / 6 |
| Compressor staging | Continuously variable | 6 / 6 |
| Connected capability | No | 6 / 6 |
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.
