Ranked #5 in Best Portable Air Conditioners

Black+Decker BPACT12HWT

3.9

2 sources1 derived$539.99as of Aug 1

The Black+Decker BPACT12HWT is the year-round pick, a 4-in-1 unit that adds a heater to the usual AC, dehumidifier, and fan, covering rooms up to 550 sq ft. Installation is easy on this single-hose design, and casters and handles make it simple to move. Real SACC cooling capacity is modest (~6,000 BTU) despite the 12,000 BTU ASHRAE label. For a buyer who wants heating and cooling in one affordable, portable box, it fills a niche nothing else here does.

Strengths

— 4-in-1 unit adds heating for year-round use, not just summer cooling
— Cools and heats rooms up to 550 sq ft
— Quiet once the room reaches the set temperature

Watch-outs

— Single-hose design is less efficient than dual-hose units
— Real SACC cooling (~6,000 BTU) is far below the 12,000 ASHRAE claim
— Can be loud while actively cooling

Ranked #4 in Best Portable Air Conditioners

LG LP1419IVSM

3.9

2 sources

The LG LP1419IVSM is a powerful, quiet single-hose portable AC built around LG's dual-inverter compressor. LG rates it as low as 44 dB, which is bedroom-quiet for a single-hose unit. A high real SACC rating and Wi-Fi control make it 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
— Large and heavy at roughly 70 lbs and 2.5 feet tall
— Premium price

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.
