Ranked #3 in Best Portable Air Conditioners

LG LP0621WSR

4.0

2 sourcesall derived

The LG LP0621WSR is the small-room value pick: a compact 8,000 BTU ASHRAE (6,000 BTU DOE) unit that cools spaces up to 250 sq ft quickly and quietly for less than the bigger units here. Reviewers praise its ease of use and fast small-room cooling, noting it runs as low as 51 dB. It is not for large rooms and there are no smart features, but for a bedroom or office on a budget it is an efficient fit.

Strengths

— Affordable, compact unit ideal for small rooms up to 250 sq ft
— Quiet at low fan, as low as 51 dB
— Easy single-hose installation and intuitive controls

Watch-outs

— Low 6,000 BTU DOE capacity limits it to small spaces
— Single-hose design is less efficient than dual-hose units
— No Wi-Fi or inverter; basic feature set

Ranked #2 in Best Portable Air Conditioners

Whynter ARC-14S

4.0

2 sources$436.37as of Aug 1

The Whynter ARC-14S is a long-running dual-hose portable AC that cools hard for hot climates, though 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 is still a solid dual-hose option, but at over 80 lbs with no handles, plus louder and 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 LP0621WSR

The smallest and most affordable unit here, sized for rooms the larger Midea Duo MAP12S1TBL, LG LP1419IVSM, and Whynter ARC-14S would over-cool. Like the LG LP1419IVSM and Black+Decker BPACT12HWT it is a single-hose design, so it is less efficient than the dual-hose Midea Duo, but its low capacity is well-matched to small spaces.

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.
