Frequently Asked Questions by Customers
What cooling capacity does the LW1522IVSM have, and how large a room can it handleIt delivers 14,000 BTU of cooling, suitable for about 700 square feet.
Which compressor and refrigerant are usedA variable-speed rotary (dual-inverter) compressor is used, and the refrigerant is R-32.
How efficient is the unitThe CEER rating is 14.7, making it relatively energy efficient compared to many standard units.
What are the noise levels in different modesAt high it’s about 58 dB, in mid-settings about 55 dB, on low about 52 dB, and in sleep mode drops to ~44 dB.
What are its dimensions and weightIt is approximately 23.63 inches wide, 28.78 inches deep, 15 inches high and weighs about 85 pounds.
What electrical specs and window fitting are requiredIt runs on 115 volts, uses a 15-amp plug, draws about 12 amps during cooling; fits window openings from 27 to 39 inches in width and minimum height of about 16 inches.
What special features does it includeIt has WiFi (LG ThinQ), works with Alexa and Google Assistant, four cooling fan speeds plus fan-only modes, cool/fan/dry mode, 4-way air deflection, a 24-hour timer, auto restart after power loss, a washable filter with a filter-check reminder, remote control, and a sleep mode.
What warranty is offeredIt comes with a one-year warranty for parts and labor.
Pros
High cooling power: Suitable for large rooms (~600-800 sq ft), delivering strong performance.
Good energy efficiency: Dual-inverter design means it uses electricity more efficiently; lower power draw, particularly in partial load / lower cooling demands.
Quiet operation at low / sleep mode: Very manageable noise (~44 dB) in quieter modes, which is good for bedrooms or overnight use.
Smart / remote control features: You can control via LG ThinQ, app + voice assistants; timer and modes help optimize comfort.
Feature-rich: Multiple fan and cooling speeds, auto-restart, dehumidification, washable filter, etc. offer flexibility and lower maintenance.
Good value for large capacity: Compared to fixed-speed non-inverter units with similar BTU, this should give better cooling with less wasted energy.
Cons / Trade-Offs
Size, weight, installation demands: It’s bulky and heavy (≈ 85 lb), so installation will require care. Window size must meet the minimum open dimensions, and support will be needed.
Noise at higher settings: While low/sleep mode is quiet, when running full-cooling or at high fan speeds, noise will be noticeably louder.
Upfront cost: More expensive to purchase than simpler, non-smart, or non-inverter ACs.
No heating function: Only cooling + dehumidifying / fan; not for heating.
Operating cost still not negligible: Even with efficiency, using it heavily (e.g. during hot seasons, or running constantly) will still add up to electricity bills.
Smart features / warranty / service support concerns: As with all smart appliances, local service support, spare parts, compatibility with local voltage and standards, and warranty handling are important. If these are weak in your area, that could reduce value.
Conclusion
The LG LW1522IVSM is a powerful, efficient, and quiet window AC that shines in large rooms or open spaces. Its dual-inverter compressor and smart controls make it a step above traditional window ACs in both comfort and energy savings.
