Both can cool through ducts; the key difference is whether the outdoor system also supplies heat.
| Decision | Central AC | Heat pump |
|---|---|---|
| Cooling | Yes | Yes |
| Heating | No | Yes |
| Efficiency metrics | SEER2 / EER2 | SEER2 / EER2 / HSPF2 |
| Existing furnace | Common paired route | May remain as dual-fuel backup |
| Quote focus | Cooling load and ducts | Heating load, balance point and backup |
