Look for Hisense 1.5hp or Midea 1.5hp. Go for inverter since gahmen will subsidize some for you. Best feature for inverter would be the ability to keep temperature stable. (Conventional AC use On-Off cycle to maintain temperature, inverter use a curve to ramp up or down your compressor instead).

Similar feedback for both brand. Both inverter AC. Cool quickly and never had issues. Survey around shopee, many part can be purchase if any issues

Inverters are not as cold as nons. If for a small room then no difference but for bigger rooms there will be a difference. I know la....I used both before.

Well, that's how it is supposed to work isn't it? When the room hits the set temperature, let's say 24°C, then the inverter a/cond can output 23°C air to maintain the set temperature and save power.
The non-inverter a/cond in the same situation will sense when the room becomes 25°C then hit full power and produce 16°C air to cool the room back down, and only stop once the internal hysteresis determines that the set temperature can be met. So if you stand in front of an inverter a/cond the air feels less cold.

I can confirm your findings, inverter saves power right from you first turn the AC on, the ramp up time is very slow. It will calculate target temperature VS room temperature and slowly ramp cooling power, usually it only run the compressor full tilt for a few minutes then ramp down to slowly cools the room. Inverters perform best when sized appropriately for the room.

Recently my house and bedroom got flooded and move to my brothers room upstairs with Conventional AC. Wife complained the room is too cold and temperature fluctuation too much. Even wifey who knows nothing of inverter vs non inverter can notice the difference in comfort.

Me different feeling, the 1.5hp inverter give better cooling for my room than previously non inverter 1.5hp. Maybe the old AC is too old.

In my case non inverter daikin 1.0hp aircond
Set to 24 on medium speed, the temperature just nice, but sometimes set to 23
Nowdays the weather kindda hot, cannot tahan

I bought Hisense 1.5Hp inverter 5star replacing an old Panasonic 1.0Hp non inverter from 13 years ago.

It cools slower than the panasonic, but i can sleep better with the hisense one. i guess becoz inverter. Tak cucuk hidung. Electric bill also cheaper with same usage pattern.

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

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

You have a incomplete understanding of how inverter saving money.

Let me give you 2 extreme examples to illustrate you lack of understanding.

If you put a 1HP invertor and a 1HP non-invertor aircond in a huge community hall. You will NOT save money and you will find the hall not cool. Reason is because BOTH are NEVER able to reach the set temperature and RUNNING AT FULL POWER. In fact, at FULL POWER, a non-invertor may even use a bit MORE electricity (or slightly worst)

Now, if you put a 2 HP invertor vs a 2 HP non-Invertor in a bedroom, I can guarantee you will save money with the invertor

This is why, for Invertor, it is always a good idea to go a bit bigger. Personally, if a room need a 13000 BTU non-invertor, I will put a 18000 inverter instead. Cool much faster and saving ~40% money.

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.

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.

Fair enough but then like i said, when you recommend most people to set this temp range, they will go like "har? Cold enough? Buy aircond for what?". So I usually recommend them to just set 23 - 24 if they are not ok with anything more, at least still better than those who set below 23c. Personally i always set to 24, increase to 25 on cooler days

By the way, yesterday I bought AC spray at Mr Diy, opened up all AC at my kampung house, sprayed this liquid to the coil and blower, and cleaned the filter net with foam b4 install back all together.
All noted massive cooling feedback than previously, as I noted too many dust, collected at the blower area.

Previously i did the same thing, then everything works perfectly
Then i did a full service 2 months after that, the aircond guy asked me did you use those aircond spray cleaner, i said yes and why... He told me the dirt from the front been pushed backwards which makes clean job harder.. I just ignored him since i dont know bout aircond stuff, all i know clean the filter once in every 2 weeks 🤔🔥

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