Indoor configuration coverage
1 of 1 EPA records for this model do not list individual indoor units. EPA’s reporting template permits this for multi-split systems. Manufacturer-documented kits are identified on their individual source pages. These rows identify an outdoor-model rating and do not establish a complete matched system or compatibility with an arbitrary indoor unit.
Heating performance & equipment details
Ranges include the 1 published source records for this model. Values in different rows may describe different configurations. Open an individual record to compare values from the same test configuration.
| Reported field | Value / range | Records supplying it |
|---|---|---|
| SEER2 · BTU/Wh | 21.2 | 1 / 1 |
| EER2 · BTU/Wh | 13.15 | 1 / 1 |
| HSPF2 · BTU/Wh | 8.9 | 1 / 1 |
| Cooling capacity · BTU/h | 18,100 | 1 / 1 |
| Heating capacity at 47°F / 8.3°C · BTU/h | 19,282 | 1 / 1 |
| Heating capacity at 17°F / −8.3°C · BTU/h | 11,575 | 1 / 1 |
| Equipment / loop type | HP - Split System | 1 / 1 |
| Refrigerant / source-reported GWP | R-32 (GWP:675 | Lower GWP) | 1 / 1 |
| Compressor staging | Continuously variable | 1 / 1 |
| Connected capability | No | 1 / 1 |
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.
Source ratings & listed systems
Each row is one source record. The component column distinguishes listed combinations from outdoor-model ratings without an indoor configuration.
