| EER2 · BTU/Wh | 11.7–12 | 231 / 231 |
| HSPF2 · BTU/Wh | 7.8–8.5 | 231 / 231 |
| Cooling capacity · BTU/h | 38,000–41,500 | 231 / 231 |
| Heating capacity at 47°F / 8.3°C · BTU/h | 38,500–40,000 | 231 / 231 |
| Heating capacity at 17°F / −8.3°C · BTU/h | 25,000–26,200 | 231 / 231 |
| Heating capacity at 5°F / −15°C · BTU/h | 18,700–20,000 | 231 / 231 |
| COP at 5°F / −15°C | 2–2.3 | 231 / 231 |
| Equipment / loop type | HP - Split System | 231 / 231 |
| Refrigerant / source-reported GWP | R-454B (GWP:470 | Lower GWP) | 231 / 231 |
| Compressor staging | Single stage | 231 / 231 |
| Connected capability | No | 231 / 231 |
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.
