Summary
Hushed, efficient cooling for larger spaces at a surprisingly competitive price. Reddit users consistently praise LG window units for quiet operation and reliability.
The top portable AC pick for anyone who can't install a window unit. Dual-hose design makes it genuinely more powerful and efficient than single-hose portables.
Pros
- 12,000 BTU handles larger rooms (up to ~550 sq ft) effectively
- 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
- 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
Cons
- 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
- 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
Our take
If your room is too big for the Midea 8K, this LG is the move. WIRED calls it 'hushed, efficient room cooling at a surprisingly low price' — and Reddit backs that up hard.
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.
