What Size Room Can the Whynter ARC-14S Cool?

Short answer: Whynter lists the ARC-14S for rooms up to 500 square feet.

That is a useful starting point, not a promise that every 500-square-foot room behaves the same. A sunny top-floor room with weak insulation can be a much harder cooling job than a shaded basement of the same size.

Start With Floor Area

Measure room length × width to get square feet. Then account for the things that add heat or change the effective room volume:

• High ceilings
• Large west- or south-facing windows
• Poor insulation
• Multiple people
• Gaming PCs, servers or other heat-producing electronics
• Open doorways into adjacent spaces

Remember Which BTU Number You Are Comparing

The ARC-14S is 14,000 BTU under ASHRAE and 9,500 BTU under DOE/SACC. When comparing it with another portable AC, use the same rating method on both units.
