With a high real SACC rating and Wi-Fi control, it is the top single-hose pick, trailing only the dual-hose Midea Duo on pure efficiency.

Strengths

— Dual-inverter compressor runs as quiet as 44 dB, great for bedrooms
— Fast, powerful cooling — drops a 150 sq ft room 15 degrees in 30 minutes
— High real SACC capacity that beats most single-hose competitors

Watch-outs

— Single-hose design is inherently less efficient than dual-hose

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

LG LP1419IVSM

The best single-hose unit here, using an inverter compressor like the Midea Duo MAP12S1TBL for quiet operation — but as a single-hose design it is less efficient than the dual-hose Duo. It cools faster and quieter than the dual-hose Whynter ARC-14S and the Black+Decker BPACT12HWT, and it is far more powerful than the small-room LG LP0621WSR.

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.
