| EER2 · BTU/Wh | 11–12 | 207 / 207 |
| HSPF2 · BTU/Wh | 8–8.5 | 207 / 207 |
| Cooling capacity · BTU/h | 44,000–47,000 | 207 / 207 |
| Heating capacity at 47°F / 8.3°C · BTU/h | 41,000–46,000 | 207 / 207 |
| Heating capacity at 17°F / −8.3°C · BTU/h | 35,200–37,800 | 207 / 207 |
| Heating capacity at 5°F / −15°C · BTU/h | 27,400–29,400 | 207 / 207 |
| COP at 5°F / −15°C | 1.68–2 | 207 / 207 |
| Equipment / loop type | HP - Split System | 207 / 207 |
| Refrigerant / source-reported GWP | R-410A (GWP:2088) | 207 / 207 |
