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 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.
