Used for years Good A/C's Warranty coverage sucks
on August 3, 2022

Verified Purchase:Yes
Installed a new, out of the box, LW1821ERSM and it stopped running within 24 hours. Electronics in cover defective. Tested with cover from another new unit and ran perfectly. Have now been in a que for warranty service for almost a month. Have used LG window units for over a decade in 25 residential units and have had warranty problems before. I am not very encouraged based on past experience.
Pros: Style/Design

Everything I expected!

[This review was collected as part of a promotion.] I purchased this using it to cool a walk-in cooler for our vegetable production. Since installing it, I haven't had to worry about vegetables spoiling in the summer heat one bit. The AC unit runs quietly and efficiently and I'm always surprized at how cool the cooler is!
Pros: ease of use, Performance

[This review was collected as part of a promotion.] This unit is quiet and cools one room to cold and doesnt distribute the cool air like my previous unit. The energy efficient newer units are not cooling efficiently unfortunately

Cheap plastic cover produces loud noise
on August 9, 2024
Posted by: jerrycast

[This review was collected as part of a promotion.] It does the job, but the plastic cover that goes around the front of the unit is cheap plastic that tends to vibrate excessively and produces a very distracting noise.

Hi, Jerry. Thanks for sharing your thoughts on the LG Air Conditioner (LW1821ERSM) model. We’re glad to hear that the unit meets your needs. However, excessive vibration and noise from the plastic cover can be quite distracting. We strive to provide top-notch products that exceed our customers' needs and expectations.

To address this, try tightening any loose screws or fittings around the cover. Sometimes, securing the cover more firmly can reduce vibrations and noise.

Please send us a private message on social media @LGUSSupport if you continue to experience issues or need further assistance. We’re here to help and ensure you get the best performance from your LG unit. ^Juvy
