Product hub: The Whynter ARC-14S is a dual-hose portable air conditioner rated at 14,000 BTU under the older ASHRAE method and 9,500 BTU under the DOE/SACC method. Whynter lists coverage up to 500 square feet.
Those numbers are exactly why portable AC shopping gets confusing. The unit has two legitimate BTU ratings, room size matters, window fit matters, and drainage can change with humidity.
Core Size and Capacity Specs
| Specification | Published value | Why it matters |
|---|---|---|
| ASHRAE cooling rating | 14,000 BTU | The older laboratory rating commonly used in product names. |
| DOE/SACC rating | 9,500 BTU | Better reflects portable-AC real-world losses. |
| Coverage | Up to 500 sq ft | Whynter’s published room-size target. |
| Hose system | Dual hose | Separate intake and exhaust paths help limit negative room pressure. |
| Power | 1,300W / 11.6A max | Important for outlet and circuit planning. |
| Dehumidification | 71 pints/day | Moisture removal can be significant in humid rooms. |
| Window kit | About 20 in min, up to 46–56 in depending on current kit/version | Measure the actual window before buying. |
| Unit dimensions | 16 × 19 × 35.5 in | Floor-space and storage planning. |
| Weight | 73 lb | Portable on casters, but not lightweight. |

Best Second-Level Questions
- Why is the ARC-14S listed as both 14,000 and 9,500 BTU?
- What size room can the ARC-14S cool?
- Do you have to drain the ARC-14S?
Dual Hose Changes the Airflow Problem
A single-hose portable AC exhausts room air and can pull replacement air into the room through gaps. A dual-hose design uses one hose for intake and one for exhaust, which helps reduce that pressure penalty.
The Window Kit Is Part of the Fit
Whynter provides a sliding window kit, but current product/manual pages show slightly different maximum lengths depending on version. That is a good reason to measure your window opening and verify the kit included with the exact unit you are buying rather than assuming every ARC-14S package is identical.
