| Service Detail | Why It Matters |
|---|---|
| HERS / duct-leakage test on completion | California requires it on new systems — it's the number that proves the ducts don't leak |
| Manual D duct sizing, not just Manual J on the box | The right-size unit on the wrong ducts still leaves hot and cold rooms |
| Low-GWP refrigerant — R-32 or R-454B | New units are moving off R-410A; ask what yours ships with |
| Electrical panel capacity checked before an all-electric swap | A heat-pump changeover can need a panel upgrade nobody quoted for |
| Refrigerant line set — reused or replaced? | Old lines often can't carry a new refrigerant type; reusing them can risk the warranty |
