| EER2 · BTU/Wh | 11.7–14 | 63 / 63 |
| HSPF2 · BTU/Wh | 7.8 | 63 / 63 |
| Cooling capacity · BTU/h | 21,200–24,000 | 63 / 63 |
| Heating capacity at 47°F / 8.3°C · BTU/h | 22,400–23,800 | 63 / 63 |
| Heating capacity at 17°F / −8.3°C · BTU/h | 14,200–15,200 | 63 / 63 |
| Heating capacity at 5°F / −15°C · BTU/h | 10,900–12,200 | 63 / 63 |
| COP at 5°F / −15°C | 1.8–2.06 | 63 / 63 |
| Equipment / loop type | HP - Split System | 63 / 63 |
| Refrigerant / source-reported GWP | R-410A (GWP:2088) | 63 / 63 |
