Pros

• All-season capability: Offers both cooling and heating, so the unit works year-round rather than just in hot months.
• Power for large spaces: Can cool large rooms up to ~1,400 sq ft, which is great for big living rooms, halls, open-plan spaces.
• Strong airflow & dehumidification: Helps reduce humidity and makes the space more comfortable, especially in humid climates.
• Convenience features: Timer, auto-restart, washable filter, airflow control (4-way), remote control make usage more flexible.
• Good build & installation design: Slide-in/out chassis helps with installation, the large weight and structure suggests good durability.

Cons

• High power requirement: Needs 208-230 V and draws substantial current, especially in heating mode. If your power supply or wiring isn’t strong enough, there may be costs to upgrade.
• Large size & weight: The unit is heavy (~140-145 lbs), bulky depth, so installation needs strong support, proper window size, and likely can’t be moved or fitted easily.
• Noise on high output: On high cooling/heating or fan speeds, noise levels are relatively high; in quieter settings this might be noticeable.
• Efficiency not top-tier: While offering large capacity + heating, its energy efficiency (for both cooling and heating) is moderate—so electricity bills will be significant if the unit is used heavily.
• Cost of ownership: Besides purchase cost, running costs (electricity), installation (brackets, wiring), and maintenance will add up.
• Supplemental heat: The heating function is supplemental — sufficient for moderate cold but not intended to replace a full-scale heating system in extreme cold climates.

Conclusion

The LG LW2423HR is a very capable unit for someone who needs strong cooling and heating in a large space. If your room is big (~1,300-1,400 sq ft), you have 230V supply, and you value both functionalities, this can be a good investment.
