2 sourcesall derived

  • — Class-leading CEER of 15.5, far above the 12.8 federal minimum

Ranked #4 in Best Window Air Conditioners
Midea MAW08HV1CWT 8,000 BTU Smart Inverter Window AC
2 sources1 derived$319.99as of Aug 1

The Midea MAW08HV1CWT is the window unit to reach for in a medium room. Its variable-speed inverter compressor sips power and avoids the jarring cycling of cheaper ACs, and the 4-in-1 design adds dehumidify, fan, and a supplemental electric-heat mode. TechGearLab named it the best all-around pick, and its 350 sq ft coverage suits most bedrooms and living rooms. It is not silent, but it is efficient, smart, and genuinely a year-rounder.

Strengths
  • — 4-in-1 inverter unit cools, dehumidifies, ventilates and heats, so it earns its window slot in shoulder seasons too
  • — Variable-speed inverter holds the set temperature without the loud on/off cycling of single-speed compressors
  • — TechGearLab's top do-it-all pick; dropped a test room 10.9F in one hour
Watch-outs
  • — Heat mode is electric-resistance and only takes the edge off in mild cold, not a furnace replacement
  • — Measured 50.5 dBA on high at four feet, audible during quiet TV or calls
  • — App setup and Wi-Fi pairing can be fiddly on first install

How they stack up

LG LW6023IVSM 6,000 BTU Dual Inverter Window AC

The most efficient and the smallest-capacity unit here, ideal where the 8,000 BTU LG LW8017ERSM and the Midea MAW08HV1CWT would be overkill. It is quieter than the LG LW8017ERSM thanks to its Dual Inverter, though the U-shaped Midea MAW08V1QWT is quieter still.

Midea MAW08HV1CWT 8,000 BTU Smart Inverter Window AC

More versatile than the LG LW8017ERSM thanks to its inverter compressor and added heat mode, though the LG is cheaper. Not as whisper-quiet as the Midea MAW08V1QWT U-shaped unit, but easier to find in stock and a simpler install.
