what brand best ?

Replaced my 11 years old daikin inverter aircond 5 weeks ago with China brand TLC 1.5hp inverter aircond for RM1.35k included installation from Shoppe. I would say good and cool, I noticed used 1kw less electricity daily compared with the old daikin aircond.

Ts, better to sleep in another room if u have empty room available.

My master room also same case, due to prolong west sun from 3pm to 7pm no matter what we do the room it's always super hot.

An update. so far so good. Settting the temp to 24 to 26 is ok fine. Sometimes just need to set the fan speed from auto to 2-3 bar.

If under extreme hot weather. Switch on the airocn and set it to full blast for about 30mins to 1 hour then manual change to usual setting.

Tnb bill also normal now no more special hike price from aircon.

For extreme hot room getting an extra 0.5hp does indeed make a difference. Inverter aircon made sure get more horsepower cause not same as non inverter aircon.

Of course. AC tech changed a lot in 11 years, it doesn't really matter what brand, most minstrels brands will see big energy improvements
