I’ve been in HVAC for 20+ yrs. and never thought I’d buy a “window shaker” as I’ve always promoted ductless mini split systems with inverter technology. When I saw the LG LW1022 with dual inverter as an option to cool my South Texas home workshop at a fraction of the cost of the ductless mini split systems, I figured I’d give it a shot. LG has a game changer with this unit. With the variable speed fan, paired with the dual inverter compressors, it is as quiet and efficient as most of the mini split systems I’ve promoted for years, and I promise there’s no window shaking!
