i assume 5 stars rating a/c? whats your suggestion brand model? I think 1 or 2 hp a/c for small-medium bedroom

Inverter.

Brand Model is just a gimmick.

yes inverter is technology

Doesnt matter in terms of brand, as long as its 5 star and higher BTU, then you are fine.

wah so many sifu here. tqtq

but how about reliability though?

Also dont put temp below 25. According to yt i watch. heh. dunno la.. xD so far i use also 25 lowest. and on like 5 hours only. bill every month 200. sometimes every night use, last week and this week 1 week no use AC. maybe this month bill lower a bit

betul ka ini statement?

me always 18 - 19 and use more than 12 hours .
TNB around rm315.00.

Wrong. Inverter aircond provide savings once it reach the desired temperature. How many hours run perday does not matter. What matter is how fast the you got the ROI from paying higher priced inverter aircond from running just a few hours per day.

me put 27C overnight every night. monthly bill < 100

that's what I heard also, considering how inverter tech functions...

i thought inverter tech uses a device to constantly keep temp at desired level, where by conventional is still uses the compressor start-stop tech in which the start-stop process itself consumes more electricity, hence higher bill... no?

The longer hours the better. But for me 25 already cold enough.. plus i turn on fan haha..

wa. 27 also cold ad actually. u got on fan? or just ac?

Yes. Once reach the desired temperature, the aircond does not need to run at 100% anymore, the compressor is capable to run at lower speed, without having to off/on. This is where the savings comes from.

before bed, with table fan. bedtime only a/c. if weather too cold, off a/c, on table fan.

and my stupid table fan speed 1 is 2, then 2 is 3. 3 is... 3 lo...

Inverter have made it more cooler with less power. Just think the savings.

BTU based on sizing room and Energy efficiency, Also the energy input. Inverter gave better yield.


Reliability = Panasonic have the say. Others its a hit and miss.

You should install solar PV system too, reduced reliance on grid and keep you cool whole day.

lol. i on fan and ac. thats why sometimes 6am still so cold even though i set timer at 2.30am to off. I turn on anytime i feel hot, so roughly about minimum 4 hours. xD

LOL 25 for me so hot.

haha.. u on fan bo? xD i on fan oh.. thats why so cold haha

LOL no as "they" said so itchy after fans on. LOL

use temp 23-25 normally cold enough for your room. put in energy save mode is also good enough.

24-25, Panasonic Inverter, 2hp. Daily usage 7-8 hours. TNB Rm65++. (included other household electronic usage like water heater, fans, computer 9am-8pm weekdays)

The installer or seller can advise the aircond size required or you can Google for it like
https://www.omnicalculator.com/construction...ioner-room-size

YouTube by local said like this aircond high current because never shut down aircond if temp setting below 25C..... blah... blah... blah. It is just simply blank statement. If like that, why aircond have temp until 16C?

It is all depend on how good the room isolated from external heat. Unlike in the 4 seasons country, our wall is just brick that exposed to sun on the outside. The hotter the wall or the more exposed to heat, then the aircond has to work harder to keep temp down. So, depend on those factor, you may reach a point where your aircond has to continuously work at full power if the temp setting is below the room ability to retain coldness. I only on my aircond just to sleep at night. So, the energy used is not much.

Any branded aircond is as reliable in my opinion. The technology has no hidden secret anymore. The brand that you can easily get support nearby is more important.

Now is the right time to buy because you can get RM200 rebate.

You can claim yourself but the shop where I bought aircond do it for me and immediately deduct my purchase price.

haha. itchy meh? lol. i okay jer.. lol

Hi, I have assembled a list of the most energy-efficient air-con units available in Malaysia.

Hope this helps in your purchase decision

No and yes.

Inverter uses DC motor, so the motor speed can be varied, by varying the motor rpm, then cooling effect can be controlled and more constant with feedback loop.
Once cool, motor run at low speed.

Non-inverter uses AC motor, it is either on 100% or off. So either cool or no cool air.

Inverter can consume as much as non-inverter if it is running 100% like non-inverter, if the preset temperature is too low like 18c and the room has difficulty to reach that temp due to too open space.

The saving amount is largely depended on your preset temperature on the remote.

Most power save air-cond i have at home is the air-cond that i never turn it on...

I'm responding to this thread again as it popped up in main page.

The question was about the most saving air-cond. So, one is it has to be inverter but which one?

As far as I know the best one is Mitsubishi. In case you don't know, there are 2 Mitsubishi air-cond manufacturers:
1) Mitsubishi Heavy Industries
2) Mitsubishi Electric (formed at later date)

The Mitsubishi Heavy Industries (MHI) is the most efficient one and it is very quiet during operation. The reason is it has more cooling fins than most other brands including Mitsubishi Electric (if not all). Therefore the fan no need to blow so loud. Having more surface, the cools the room much faster. The only negative side is that since the fins are close together, it can easily be block in dusty environment. Need more regular cleaning on fins.

MHI PN SRK...typically 4 star
ME inverter get 5 star ST.
Personally MHI is the budget brand

Recently I did market survey on 1.5HP inverter aircond.
Panasonic X-Premium model seems the way to go for me as it CSPF rating higher than any other 1.5HP models in the market.
Daikin Smarto (FTKH) series also not bad, very efficient too. Summore more silent compressor than Pana.

Yes, I saw in Mid Valley. The Panasonic brands are more energy efficient. A 1.5HP is 1400kwh/year. A 1hp is 850kwh/year.

Hi,
My panasonic A/C has energy label of 3526kwh/year.
I think they use 12 hrs calculation and 365 days?

So is it 0.8kw/hr? and multiply with 0.22c for tier 1, only 0.17cents per hour of use?

got myself FTKU 1.5 and 1.0 HP.
I Tried running 1.5HP 23Celcius for 3hours - 3hours 15min and when i check TNB daily usage show 86cent.. duno how accurate it is.
still not yet move in. so now can test aircond power consumption

1HP = 853kwh per year
1.5HP = 1068kwh per year

Mine is 2.5hp non inverter at living room. 3000 plus kwh/year

owh then need compare with 2.5HP .. mine max 1.5hp only

Not recommended to buy Gree, lots of my relatives used it, and most of them having trouble of it leaking and malfunctions. Still prefer Panasonic and Daikin.

Panasonic still the way to go, even asking the people who service and repair airconds. More reliable and spare parts easy to find + cheaper.

Temp is usually 25 - 27 used for sleeping. 3 AC with bil 50 - 80 every month.

Can you define leaking and malfunctions? As in the gas is leaking, or condensate dripping, or condensate not flowing, etc? So what is the malfunction after that?

Leaking as in water leaks, malfunctions as it doesn't work anymore after some years. I visit my cousins every year, so I noticed them installed a new Gree aircon, then after around 3-4 years, my cousin mentioned that it doesn't work anymore. In between they also mentioned that it keeps on leaking. The visits were during CNY, and it was installed before MCO.

My mom's main company is distributor for Gree, and her working branch office also having the same issue with some Gree aircon leaking water.

Can you imagine Gree, being the largest air cond manufacturer in China, making a faulty production run? There'd be 1k complaints on that model!

But your story sounds like a bad installation from a lousy technician.

any inverter aircond with 5 star rating will do

Really wonder why Mitsubishi Electric is not in the list…. Very doubtful & suspicious

Set temperature at 16c to 23c Vs 25c to 26c, energy's efficiency is a lot different.

I believed 26c is the best for energy savings…
I’m using an 11/12yrs old Mitsubishi Electric standard inverter model, 1hp.

mine non inverter aircond always set to 23 & sometimes 24

Non inverter base temperature in 20-23c to avoid at midnight around 3-4am the compressor keep on and off

so what temp should i go for ?

16 years ago, I set on 23c to avoid keep repeating on and off.
Day time no issue for 24-25c
Sorry, long time no use non inverter already.

so if i set 22c and 23c should be fine
