Pros

• High cooling capacity: Great for large rooms (up to ~1,000 sq ft). If your space is big, this model can keep it cool reliably.
• Good power efficiency for its class: While not the top-of-the-line inverter model, its EER/CEER ratings are decent for an 18,000 BTU unit.
• Solid airflow and dehumidification: The unit moves a good amount of air (≈ 530 CFM) and removes moisture, which helps comfort in humid conditions.
• Convenience features: Auto-restart after power cut, a timer, filter alarm, Energy Saver mode — all useful for reducing hassle and energy waste.
• Durable / well-built: Slide-out washable filter, robust physical size, useful for heavy-duty cooling.

Cons

• High noise at full power: At the highest fan/cooling mode, the sound (~60-65 dB) will be noticeable, especially in quiet settings.
• Large and heavy: The size and weight (~130 lbs) mean installation is non-trivial. You’ll need a supportive window frame or sleeve and likely help.
• High power & electrical requirements: Needs 208-230V supply; if your local setup is different, you'll need provisions (transformers or wiring) which add cost.
• Moderate efficiency vs premium inverter models: There are units with higher efficiency and variable speed compressors that do better on electricity costs.
• No heating mode: This is a cooling (and dehumidifying/fan) unit only. If you need heating too, you'd need a separate system.
• Upfront cost and running cost: Big capacity, big energy draw. Even though reasonably efficient, running it a lot will mean significant electricity usage.

Conclusion

The LG LW1816ER is a strong pick if you have a large space to cool and power infrastructure that supports 208-230V. It delivers solid, dependable cooling, good airflow, and features that help with convenience and some energy savings.
