| EER2 · BTU/Wh | 12–12.5 | 9 / 9 |
| HSPF2 · BTU/Wh | 7.8 | 9 / 9 |
| Cooling capacity · BTU/h | 17,500–17,600 | 9 / 9 |
| Heating capacity at 47°F / 8.3°C · BTU/h | 16,000–16,500 | 9 / 9 |
| Heating capacity at 17°F / −8.3°C · BTU/h | 10,100–11,800 | 9 / 9 |
| Heating capacity at 5°F / −15°C · BTU/h | 8,000–10,200 | 9 / 9 |
| COP at 5°F / −15°C | 2.04–2.48 | 9 / 9 |
| Equipment / loop type | HP - Split System | 9 / 9 |
