How they stack up

Black+Decker BPACT12HWT

The only unit here with a built-in heater, making it the year-round choice the cooling-only Midea Duo MAP12S1TBL, LG LP1419IVSM, Whynter ARC-14S, and LG LP0621WSR lack. As a single-hose unit it is less efficient than the dual-hose Midea Duo and Whynter ARC-14S, and its real cooling capacity is closer to the small-room LG LP0621WSR than its 12,000 BTU label implies.

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.
