Malaysia sometimes have horrific heat wave that comes from hell.... and that's when I really regretted buying the Inverter. Really regret. On paper yes la.... save electric ( a bit only) but in reality once the heat wave comes...you will wish you bought the non inverter

There is absolutely no difference between an inverter and non inverter when it comes to cooling capacity. The difference nowadays is with R32 consuming a lot less power but at the cost of slightly less cool air. If you really want those ice cool wind, get a R410a unit but prepare to pay twice the electricity.

Inverter real benefit is when you turn on for long hours, set at 23 - 25c range, and the HP is appropriate for the room / area size. The faster it can reach the target temp, the sooner the inverter kicks in, the more energy you save. That's why generally its more suitable for bedroom or study / office room.

If you like to set below 20c, your aircond HP is underspec-ed for the room, or you want to turn on for awhile then turn off (< 3 hours), it kind of defeat the purpose of inverter already

For large areas like living room, can still consider go for non inverter

Doubt you get much saving <25C unless you live in condo.

It should apply to any space as long your aircond hp not underspec'ed, some even recommend to overspec the hp.

23 - 24c is usually the recommended temp for energy efficiency no matter inverter or non inverter. You can also set higher since higher temp = aircond able to reach the target faster = inverter kicks in faster = more savings. But then again some will say what's the point of aircond if you set such temperature

25-26C is the temp manufacturer used to do their energy efficiency test thus I stay with this temp for both my AC. I don't believe 23-24C is efficient because I tried 25C for my LG 1hp and it used almost 30% more power than when I set mine to 26C.

Not much choice. Sure got leftover somewhere. But prepare for no spare parts in case failure.
