Ultimately, with the help of such advanced technology, Inverter air Ceiling Concealed Duct (Low Static)
conditioners are less prone to breakdown, cheaper to run and the outdoor
compressor is generally quieter than conventional air conditioners. LG
revolutionary Inverter technology boasts powerful silent performance
while minimizing energy consumption by as much as up to 40%. Btu
