Ranked #3 in Best Portable Air Conditioners

Whynter ARC-14S

4.2

$499.99as of Jun 7

The Whynter ARC-14S is a long-running dual-hose portable AC that cools strongly for hot climates, but reviewers are candid that its real SACC capacity (~9,500 BTU) falls far short of its 14,000 BTU ASHRAE claim. ConsumerAnalysis now recommends the Midea Duo over it on efficiency. It remains a solid dual-hose option, but at over 80 lbs with no handles and louder, less efficient operation, it trails the newer inverter units.

Strengths

— Dual-hose design cools more efficiently than single-hose units
— Strong cooling output for hot climates
— Eco-friendly CFC-free refrigerant and recognized brand

Watch-outs

— Real SACC capacity (~9,500 BTU) is well below its 14,000 BTU ASHRAE claim
— Very heavy at over 80 lbs with no handles, hard to move
— Loud and less energy-efficient than the Midea Duo

How they stack up

Midea Duo MAP12S1TBL

The only dual-hose unit among the top picks, which is why it out-efficiencies the single-hose LG LP1419IVSM and LG LP0621WSR. Its inverter makes it quieter than the Whynter ARC-14S and Black+Decker BPACT12HWT. The Whynter ARC-14S is the other dual-hose unit here, but it is heavier, louder, and less efficient than the Midea Duo.

Whynter ARC-14S

The other dual-hose unit alongside the Midea Duo MAP12S1TBL, but older and without an inverter — so it is heavier, louder, and less efficient than the Duo. Its dual-hose design still makes it more efficient than the single-hose LG LP1419IVSM, LG LP0621WSR, and Black+Decker BPACT12HWT in principle, though its real SACC capacity is lower than its rating suggests.
