The LG LP1419IVSM is a powerful, quiet single-hose portable AC built around LG's dual-inverter compressor. ConsumerAnalysis found it lowers a 150 sq ft room 15 degrees in about 30 minutes, and LG rates it as low as 44 dB — bedroom-quiet for a single-hose unit. 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.

  • 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

$579as of Jun 7

The Midea Duo MAP12S1TBL is the consensus best portable AC, pairing a space-saving dual-hose design with an inverter compressor for quiet, efficient cooling.

  • Inverter compressor keeps it ultra-quiet — as low as 42 dBA
  • Strong, stable cooling and humidity control even at max settings
Watch-outs
  • Heavy at over 70 lbs, awkward to move between rooms
  • Premium price for a 10,000 BTU (SACC) unit
  • Dual-hose window kit is more involved to install

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.

Midea Duo MAP12S1TBL

The only dual-hose unit among the top picks, which is why it out-efficiencies the single-hose LG LP1419IVSM and LG LP0621WSR. Its inverter makes it quieter than the Whynter ARC-14S and Black+Decker BPACT12HWT. The Whynter ARC-14S is the other dual-hose unit here, but it is heavier, louder, and less efficient than the Midea Duo.
