The Best Window Ac Units

Updated April 2026·Experts: nytimes, WIRED, The Spruce, RTINGS

Best Overall

Midea U-Shaped Smart Inverter Window AC (8,000 BTU)

$239, $380

This is the one. Wirecutter has picked it for 6 years running, Reddit loves it, and the inverter tech makes it genuinely different from every cheap box AC on the shelf. Buy this first.

What holds up

  • Inverter compressor runs near-silently and modulates between 2,000, 8,000 BTU based on need
  • Extremely low power draw, as low as 111W at partial load, max ~680W
  • No startup surge makes it ideal for generator use during outages
  • U-shaped design lets you open/close the window while installed
  • WiFi smart home integration included

What to know

  • Reports of units being removed from sale or availability issues in 2025, 2026
  • Some Reddit users report units never adequately cooled their space despite working quietly
  • 8,000 BTU may be insufficient for larger rooms without upgrading to 10,000+ BTU model
  • Higher upfront cost than basic non-inverter window units
What people say
Probably one of the best (if not the best) air conditioners to use with a generator for power outages. Inverter controlled compressor so it has no start up surge and low power usage.

Best for Large Rooms

LG 12,000 BTU Smart Window Air Conditioner

$300, $450

  • Notably quiet operation, The Spruce calls the 10,000 BTU variant 'nearly silent'
  • Smart WiFi connectivity for remote control
  • Strong community reputation on Reddit for reliability

What to know

  • Requires 240V outlet for some higher-BTU models
  • Larger physical footprint and heavier than smaller units
  • RTINGS notes they haven't been able to test LG units directly yet
  • Smart features require app setup which some users find cumbersome

Best Mid-Range

GE AHEF06BC Window Air Conditioner

$180, $280

  • Good balance of cooling capacity and price
  • GE brand reliability and wide service network
  • Efficient performance for medium-sized rooms

What to know

  • No inverter compressor, less efficient than Midea U
  • Louder operation compared to inverter-based units
  • Fewer smart features than LG or Midea equivalents

Best Portable Alternative

Midea Duo MAP14HS1TBL Portable AC

$500, $600

If your building won't allow window units or you have casement windows, stop fighting it and get the Midea Duo. It's the only portable AC Wirecutter actually recommends without major caveats.

What holds up

  • Wirecutter's top portable AC pick, quieter, more powerful, more efficient than competitors
  • Dual-hose design prevents negative pressure issues common in single-hose units
  • 14,000 BTU handles larger spaces portables typically struggle with
  • Can be moved between rooms unlike fixed window units

What to know

  • Roughly twice the price of equivalent window AC units
  • Bulky floor footprint takes up living space
  • Dual hose still requires window access for exhaust
  • Less efficient than a properly sized window inverter unit
What people say
The Midea Duo MAP14HS1TBL is quieter, more powerful, and more efficient than any other portable AC we've tested.
