Heating performance & equipment details
Ranges include the 273 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 | 273 / 273 |
| EER2 · BTU/Wh | 10–12 | 273 / 273 |
| HSPF2 · BTU/Wh | 7.8–8.1 | 273 / 273 |
| Cooling capacity · BTU/h | 32,400–35,000 | 273 / 273 |
| Heating capacity at 47°F / 8.3°C · BTU/h | 30,600–32,800 | 273 / 273 |
| Heating capacity at 17°F / −8.3°C · BTU/h | 20,400–22,000 | 273 / 273 |
| Heating capacity at 5°F / −15°C · BTU/h | 17,000–18,400 | 273 / 273 |
| COP at 5°F / −15°C | 2–2.44 | 273 / 273 |
| Equipment / loop type | HP - Split System | 273 / 273 |
| Refrigerant / source-reported GWP | R-454B (GWP:470 | Lower GWP) | 273 / 273 |
| Compressor staging | Two-stage | 273 / 273 |
| Connected capability | No | 273 / 273 |
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.
