User Experience Overview: Remote Control Praised amid Mixed Performance Feedback

Among 99 verified reviews, the LG LT1236CER scored an average of 3.8 stars. Around 65% of users appreciated the remote control’s ease of use and the unit’s low maintenance due to washable filters. However, cooling effectiveness received mixed opinions: about 40% of customers indicated the air conditioner struggled to lower temperatures below 60°F consistently. Noise level feedback was also divided, with some finding the 59 dB output acceptable while others considered it disruptive in quiet environments. A few users mentioned unexpected unit shutdowns over time.

“We love the convenience of controlling the AC from across the room,” said one purchaser. Another review noted, “Cools adequately but not as cold as expected on hot days.” A less satisfied customer wrote, “The noise is loud, and it stopped working after a few months.” This split suggests variation in performance possibly linked to installation or room conditions.
