Amana shares Goodman nomenclature. Paste your model number for an instant decode.
Always confirm against the data plate's rated capacity line — model ranges occasionally reuse digits for non-capacity codes, and the plate is authoritative.
| Capacity code | BTU/hr | Tons |

| 09 | 9,000 | 0.75 |
| 12 | 12,000 | 1.0 |
| 18 | 18,000 | 1.5 |
| 24 | 24,000 | 2.0 |
| 30 | 30,000 | 2.5 |
| 36 | 36,000 | 3.0 |

On the data plate — a metal or foil sticker on the side or back of the outdoor unit (or behind the front panel on indoor split units). Use the model number, not the serial number, which encodes the manufacture date rather than capacity.
Amana shares Goodman nomenclature. Divide the BTU code by 12 to get tons.
Paste the model number from the outdoor unit's data plate into the decoder above — it applies Amana's nomenclature automatically. Example: ASX160241 = 2.0 tons.
Amana shares manufacturing with Goodman and Daikin and embeds capacity as a multiple of 12,000 BTU/hr. Like Goodman it also recognises the code 61 as 5.0 tons.
Modern strings such as ASX140241K or AVXC200361 lead with A for the Amana line. SX flags single/dual-stage condensers and VXC a variable-speed inverter; in the ASZ family a Z at the third position marks a heat pump. The capacity is the standard step (024, 036, 048…) embedded in the string.
Older lineages use shorthand such as RCE24A, where the size digits trail the prefix without zero-padding (24 → 2.0 tons).
The decoder above applies this nomenclature automatically. Capacity codes are nominal — always confirm against the rated-capacity line on the unit’s data plate.
Capacity decoding on this page follows Amana’s published model-number nomenclature. To confirm a unit’s actual rated capacity and efficiency, cross-check the authoritative references below.
Tonnage is derived from nominal cooling capacity: 1 ton of refrigeration = 12,000 BTU/hr.
Model-number conventions and standards evolve, and manufacturers occasionally reuse digits for non-capacity codes — the rated-capacity line on the unit’s data plate is always authoritative. Figures here are for identification and planning, not a substitute for a professional load calculation.
