Experts say that portable air conditioners that use dual exhaust hoses, such as the 14,000 BTU Whynter ARC-14S, tend to perform at least a little better than single hose models, especially in larger rooms. The ARC-14S does perform well in expert tests, and user feedback is better for this portable AC unit than for most others.
- Good performance in larger rooms
- Dual-hose design for better efficiency
- Good features
- Big and heavy
- Relatively loud
- Cooling in smaller rooms not much better than a single-hose model
