| EER2 · BTU/Wh | 12–12.5 | 11 / 11 |
| HSPF2 · BTU/Wh | 7.8 | 11 / 11 |
| Cooling capacity · BTU/h | 17,500–17,600 | 11 / 11 |
| Heating capacity at 47°F / 8.3°C · BTU/h | 16,000–16,500 | 11 / 11 |
| Heating capacity at 17°F / −8.3°C · BTU/h | 10,100–11,800 | 11 / 11 |
| Heating capacity at 5°F / −15°C · BTU/h | 8,000–10,200 | 11 / 11 |
| COP at 5°F / −15°C | 2.04–2.48 | 11 / 11 |
| Equipment / loop type | HP - Split System | 11 / 11 |
| Refrigerant / source-reported GWP | R-410A (GWP:2088) | 11 / 11 |
| Compressor staging | Single stage | 11 / 11 |
| Connected capability | No | 11 / 11 |
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.
