What this code covers
Air conditioners built to be fixed in place on a window, wall, ceiling or floor. Both all-in-one (self-contained) units and split systems, with an indoor and an outdoor part, are covered. Air conditioners for cars and other vehicles, portable units and loose parts have their own codes.
How to tell it apart from neighbouring codes
| Code | Choose it if… |
|---|---|
| 841510 (this page) | The unit is made to be fixed to a window, wall, ceiling or floor, as one box or as a split system. |
| 841520 | The air conditioner is built for people in a motor vehicle (car, truck, bus). |
| 841581 | Another type of air conditioner (not fixed in place) with a refrigerating unit and a valve that reverses the cycle, so it can heat as well as cool. |
| 841582 | Another type of air conditioner (not fixed in place) with a refrigerating unit but no reversing valve, for example a cooling-only portable unit. |
| 841590 | You are shipping parts only, such as an indoor coil or a front panel. |

Common misclassifications
- Evaporative (swamp) air coolers declared as air conditioners → 847960. They cool with water evaporation, not a refrigerating unit, and have their own subheading in heading 8479.
- Heat pumps that only heat water or a building declared as 841510 → 841861. Heat pumps other than the air-conditioning machines of heading 8415 belong in heading 8418.
- Wall or window fans declared as air conditioners → 841451. A fan that only moves air, with no part that changes temperature and humidity, is a fan under heading 8414.
