Model: LW1521ERSM1
from $448
A 14,000 BTU window air conditioner with 11.2 EER efficiency rating for 700 sq ft rooms. Features smart Wi-Fi control, 265 CFM airflow, digital controls, 3-speed fan, and 53-55 dB operation. Includes remote, 1-year warranty, and 2 pints/day dehumidification.
Sizing is critical: an oversized unit cools the room too fast without removing humidity, leaving it feeling damp. U-shaped inverter models are vastly superior for noise reduction and efficiency. Available from $448.
Window ACs dramatically increase summer electric bills depending on climate and usage. Regular filter cleaning is free but essential to maintain efficiency and prevent freezing.
