Frequently Asked Questions by Customers

• What is the cooling capacity and how many square feet can it cool?
  The unit delivers 18,000 BTU of cooling and is intended to cool spaces up to about 1,000 square feet.
• Which refrigerant and compressor type are used?
  It uses R-32 refrigerant and a variable-speed rotary dual-inverter compressor.
• How efficient is the device (CEER rating) and what are noise levels in different modes?
  The CEER rating is 14.7. Noise levels are around 59 decibels on High, about 56 on Mid, about 53 on Low, and down to ~44 in Sleep mode.

  Dry air flow is about 500 CFM, and it dehumidifies approximately 4.2 pints per hour.
• What are the electrical requirements and window size compatibility?
  It requires 208-230 volts, 15-amp plug, draws around 9.2-10.2 amps when cooling. It fits window widths of 29 to 41 inches and a minimum height of 19 inches.
• What special modes and convenience features are included?
  It supports WiFi control (ThinQ), works with Google Assistant and Amazon Alexa, offers a sleep mode, auto restart after power loss, a 24-hour timer, filter check/reminder, 4 cooling fan speeds plus fan-only speeds, energy saver function, remote control, 4-way air deflection, and a slide-out washable filter.
• What are the unit’s dimensions, weight, and warranty period?
  It measures about 26 inches wide, 17.71 inches high, 30.67 inches deep, and weighs around 112 pounds. Warranty for parts & labor is one year.

Pros

1. Strong capacity for large spaces
   With 18,000 BTU cooling capacity and rated to handle up to ~1,000 sq ft, this model is well-suited for large living rooms, open areas, or spaces with high heat load.
2. Better energy efficiency
   The dual-inverter compressor plus a relatively high CEER (~14.7) mean it should consume significantly less power for the same cooling compared to non-inverter units. LG states this model offers up to ~35% energy savings over DOE’s minimum standard.
3. Quieter operation, especially at low / sleep mode
   Sleep mode noise is ~ 44 dB, which is quite reasonable for a unit of this size. For nighttime / low-demand use, that helps reduce disturbance.
4. Smart control & modes
   Includes Wi-Fi through LG ThinQ, remote control, timer, auto-restart after power outage. Also has Dry (dehumidifier) mode, Fan mode, etc. This gives flexibility to adapt to different comfort needs and weather.
5. Built quality & features
   Uses R-32 refrigerant (lower global warming potential than many older refrigerants), slide-in/out washable filter, multiple fan/cooling speeds, 4-way air deflection. These aid durability, maintenance, and comfort.
6. Good user feedback
   Users generally praise its cooling effectiveness, quietness (especially in lower modes), and it being energy efficient. Some mention it significantly cools large areas.

Cons / Trade-Offs

1. High noise at full power / high mode
   While the sleep/low mode is fairly quiet, at higher cooling or fan speeds the noise (≈ 59 dB) is fairly loud. If you run it at full capacity often (e.g. midday peak heat), it might be noticeable.
2. Size, weight, installation challenge
   The unit is heavy (~ 112 lbs) and large dimensions; installing it will likely require two people and possibly additional support/brackets. Also, the window must be sufficiently large and strong.
3. Voltage requirement
   Needs 208-230V supply, so in regions where the standard supply is lower / different, you may need electrical adjustments. This can add cost and complexity.
4. Higher upfront cost
   Dual-inverter, high-capacity, smart features cost more initially than basic ACs. While electricity savings may offset this over time, the initial investment is higher.
5. Operating cost still non-negligible
   Even with better efficiency, operating such a powerful unit (especially under high cooling demand or in hot, humid weather) will use substantial electricity.
6. Potential variation in actual cooling performance
   Some users report that although the unit cools well, it may not always respond as fast in large homes or under extreme outdoor heat. Also, in some cases, delivery/packaging damage reported.

🔍 Conclusion

The LG LW1822IVSM is a premium option among window air conditioners: it offers high cooling power, modern inverter technology, and smart features. If your situation matches what this model is designed for, it’s likely to be a strong and satisfying purchase.
