Pros

1. Good cooling capacity: This unit can cool large rooms (up to ~1,000 sq ft) which is ideal if you have living rooms, large bedrooms, or open areas.
2. Solid airflow and dehumidification: The dry airflow (~530 CFM) and decent dehumidification (~4.9 pints/hr) help keep humidity under control, improving comfort especially in humid weather.
3. Useful features for comfort & convenience: Timer, auto-restart, energy saver mode, filter alarm make for more user-friendly operation and easier maintenance.
4. Robust build & decent efficiency for class: With CEER ~ 11.8, this unit is competitive among non-inverter large capacity ACs. Though not top of the line, it's acceptable for many users.
5. 4-way air direction helps distribute cooled air more evenly, helping avoid hot spots.
6. Good physical durability: Washable filter, solid slide-in/out chassis, strong components.

Cons

1. High noise at high settings: The sound levels (~65 dB at high) will be quite noticeable. If you are sensitive to noise or need quiet in certain parts of the day, that may be an issue.
2. High voltage requirement: Needs 208-230 V supply. If your house or building uses lower voltage (110-120V) you’ll need proper wiring / circuit setup. That adds cost.
3. Large size and weight: ~130 lbs is heavy; needs strong window frame / support and careful installation.
4. No heating mode: If you want a unit that also heats, this doesn’t offer that; in places with cooler climate, that’s a limitation.
5. Efficiency isn’t top-tier compared to inverter models. If you run AC many hours per day, inverter types may give better savings.
6. No WiFi / smart control: Lack of built-in WiFi means less flexibility for remote control, scheduling via app etc. (unless an external controller is added).

Conclusion

The LG LW1824RD is a good choice if you need strong cooling for a large space, and you have the right infrastructure (window size, 208/230V supply, and structural support). It gives good cooling power, acceptable operational features, and performs well in humid conditions thanks to good airflow and dehumidification.
