I am using samsung since 4 years back.
Its still working fine.
last time i use like 10-15 days a month
now only 8-10 days a month due to outstation work.
Never even service before. its still working well.]
I wash the filter myself once in awhile.
Havent use other brand before but this unit of mine saves alot of electricity.
i use to on before 15 hours a day everyday in one month.
my electricity bill increase by less than 20 bucks LOL.
i put power saving mode. *24 celcius


If you going for non inverter then york/daikin.
Im using that also during my outstation trips.
they get cold very fast.
