Additional features include a user-friendly digital control panel, a timer, a filter check reminder light, and a power failure auto restart. The installation kit and remote control are included, but note that the unit is quite heavy at 132 pounds, which may pose challenges during installation.

The lack of Energy Star certification may be disappointing for those seeking maximum energy savings. Nonetheless, the convenience of smart features and the strong cooling capacity make this air conditioner a solid choice for larger spaces. The 24-hour timer and the filter check reminder add extra ease of use.

With its high cooling capacity, it can handle medium to large spaces effectively. The unit operates quietly at about 50-51 decibels, which is roughly the noise level of a normal conversation, so it won’t disturb your work or sleep. It also includes a heat option, making it useful year-round, and an auto-restart feature that turns it back on after a power outage, which is convenient.

Installation requires a 230-volt power source and the unit is quite large and heavy (over 140 pounds), so it might need a sturdy window and some effort to set up.

Additional helpful features include multiple fan speeds, a dehumidifier to reduce moisture, and a remote control for easy operation. It also has a filter light reminder to prompt maintenance.

The unit is bulky and may not fit all window sizes easily, and it comes with only a one-year warranty. For those seeking a reliable, powerful air conditioner that also heats your space and can accommodate its size and moderate energy use, this LG model is a practical option.
