    Both AC's Arrived Damaged

    + We had a very negative experience with this A/C. We have been Best Buy customers for a decade and have always had great experiences. We are also Total Tech members. This experience has been a nightmare. When we searched for the A/C we used Consumer Reports and this A/C was highly recommended. Only one review said A/C was damaged. We thought that it was sad for that customer that this would not happen to us. We were wrong, it happened TWICE. The customer support for Best Buy was horrible. We were promised the A/C would be picked up by our local Home Services Geek Squad since it was too heavy to lift down a flight of stairs and then out in our truck to bring back to Best Buy. This promise was broken. We were told a gift card would be given to us for receiving broken A/C. This was then denied. We have been making calls since June 18 2025 and today July 11 2025 the AC was picked up by UPS. This is not our style to give a 1 star but we did not want this to happen to anyone else. If we could we would give 0 star for the A/C and 0 star for Best Buy Customer service. PS We kept the second broken AC since we have run out of patience with Best Buy Customer Service.

    Powerful, Sleek & Quiet

    Love my AC!! I double checked w my HVAC guy too. Consumer Reports gives good rating too. Its powerful, sleek & quiet. I did get a window support bracket cuz AC Inverters are back heavy.

    Installation is difficult depending on window desi

    This is probably a great unit, however this was not designed to fit my (new) windows without excessive modifications to the window frame/sill. I have never had to think twice about installing any window unit, but this one just doesn't make sense - poor design.

    FEDEX terrible shipping

    AC might have been good if FEDEX didn't screw up shipment. I ordered this for my granddaughter. It was apparently dropped during shipping and delivery. I returned two of these for same reason. Best Buy was great, refunded money no problem but FEDEX delivery and handling were awful. I can't recommend product because it was unusable on delivery

Questions & Answers

  • What's the plug type. I had a Kenmore 24000 btu that needed a 3 prong 5 20 r plug in. Will this unit safely work with this plugin? I don't need a unit that was as large as the Kenmore. Looking for 1 with smaller BTUs that would work with my plugin.

    The NEMA Configuration for the plug on the LG 12,000 BTU High Efficiency Dual Inverter Window Air Conditioner with Wi-Fi and LCD Remote, 115V - White, Model # LW1224IVSM, is 5-15P, and it plugs into a standard 120 V, 3-wire grounding receptacle rated 15 A / 120 VAC / 60 Hz, protected by a 15 amp time delay fuse of a 15 amp circuit breaker...^Ivan.

  • Says this air conditioner air flow is 9.1 cubic feet per minute isn't that extremely low is is that for high or is that for low setting

    The listed Airflow Rate of 9.1 cubic feet per minute for the LG 12,000 BTU High-Efficiency Dual Inverter Window Air Conditioner with Wi-Fi and LCD Remote, 115V - White, Model # LW1224IVSM is incorrect. That is the air conditioner's amperage which should be listed as 9.1 A. The CFM or air flow rate for this window air conditioner is 330 cubic feet per minute...^Ivan.
