    Disappointing Customer Service Experience

    I purchased an AC unit from Best Buy that arrived with a broken fan blade, which was discovered during professional installation. As a result, I paid $200 for the initial installation and had to pay another $200 to install the replacement unit. Throughout the process, I received conflicting information from customer service regarding pickup, replacement, and compensation. Despite being assured that compensation would be provided, I was later informed that no compensation was available. To make matters worse, the replacement AC was delivered four steps below my house and left in the rain instead of being placed on my covered porch. While defects can happen, the inconsistent communication, broken commitments, and poor handling of the situation made this a very disappointing customer service experience.

    Cools and heats great! A bit noisy when cooling.

    This unit is not packaged well enough to prevent from damage during shipping. It also weighs over 130 pounds and is very large and cumbersome. The first 2 units ordered arrived damaged. Finally, the 3rd unit arrived with no damages. The front flap with filter attachment rattles and is very loud when the condenser is running.

    AS indicated in its header, the LG 18,000 BTU 230V Window-Mounted Air Conditioner with 12,000 BTU Supplemental Heat Function - White, Model # LW1823HR is a 230V unit so it must be plugged into a Standard 240 V, 3-wire grounding receptacle rated 20 A / 240 VAC / 60 Hz with a 6-20r NEMA configuration so the plug has a 6-20p NEMA configuration (i.e. one vertical blade, and one horizontal blade over a horseshoe-shaped grounding pin)...^Ivan.
