For my option and highly recommended you choose an over ME to be save place for easy clean and easy to access blower.

I just realise on York inverter really difficult to remove drain plate and after removed on the air blower was noisy at end blower rubber bearing running noise.

Inverter Aircon PCB is the one vulnerable to spoil, and it costs a lot, my previous Hitachi inverter PCB faulty in one year, I got free replacement, it spoiled again in second year, this time no more warranty, so I got Mitsubishi inverter AC, so far it has been more than 1 year and working good.

I am not sure for daikin PCB.

From my friend he works in s'pore airconds services and he told me don't buy daikin brand these is too many troubleshoot already.

Regarding PCB usually will be spoil only at outdoor unit, on my previous airconds installer for my home on Hitachi inverter 1hp, he said the board is around Rm750 for outdoor unit.

But for me on inverter PCB really durable.
ME still offering for 2 years indoor & 10 yrs for compressor and register online

I already install daikin inverter...well,hopefully it'll serve me well for long long time.

I guess all these aircord is ok...but the installer is more important...my installer reccemend me daikin for invertor...he can provide service so no worries there...

Due York DC Inverter & daikin is under one roof.
All the parts from York also quite similar like proton products, you can buy the parts as cheaper price to be compare to daikin or others.

If you know the parts then can be walk in to aircond spare parts and grab it as cheaper cost then replace by own.

Just the rubber parts won't be last longer than panasonic/ME, Daikin.

I don't know what is the price for Mitsubishi inverter PCB, but hitachi quote me RM500 for PCB.

Wait I got time and go to SIN MA in Johor jaya, JB have bigger airconds parts supplier and after bought then take picture to show u.

So far I had never change PCB before, these only took me too noisy like before panasonic non-inverter deluxe NAVI model & older hitachi non inverter 10k btu model for me is still good in condition, these is too much for energy with noisy & under cooling for Panasonic less than a year replace with ME starmex inverter & hitachi DC inverter so far so good for them still cold like when new.

I install my daikin inverter 1.5HP only rm1800...

If you intend to get an Inverter air cond, getting a more powerful air cond instead of an under-powered ones is always a good idea.

What you said is for non-inverter air cond.

Imagine you are driving a car. A car driven in city has plenty of stop start so uses more petrol. By preventing such stop-start operation (Inverter), you save petrol. A tiny air cond in a big room will never encounter that stop-start nor when you set temperature at 16C.

I have both and I can confirm if used properly, inverter indeed can save you 40%. The trick is to know what size to fit and how to use them.

I guess you are the city kid.

In before living in kampung with very weak power cable to supply all the house for electricity.

Once you switch on aircond and the warm color blub light can notices like blinking on & off.

If using higher power non-inverter aircond to be draw in high power consumption for every time on & off. The the Blub really can't last longer...lol

Yes, something like that. Try comparing the power consumption of non-inverter and inverter and you should be able to note the differences. I have similar concern as yours but settled for "over" instead of "under" power. My rationale, if over-powered, the ampere will automatically drop anyway with inverter so why worry?

I don't know about calculation but do know there are other factors to consider beside sizes. Is the room facing the afternoon sun? How many people? How often door opening and closing? etc

Seriously 4.5m x 4.5m still can fit in 1hp?

Die die must go for 1.5hp and no regret.

You just telling us, you driving kancil 660cc and fit in 5 adults and try to pull till end of accelerator to when up hill.

No worried just go for any brand model made for inverter unit.

Cause the budget still belong to you
Even York inverter I still highly to recommended

bro,your room size is 15X15 feet right...almost like mine...must use 1.5HP...haha...if you put 1HP inverter definitely not enough...mine also take like 10-15minutes to get it cool down to temperature 25Deg...but once it is on 25Deg,you'll feel comfortable...
I agree totally with you...

Why not try to get York inverter?
You didn't compare the indoor & outdoor design was almost same and only York inverter does not built in eye motion to capture human in bedroom or leaving the room to increase 1 more deg only.

York is under daikin company and sharing same technology from daikin low budget design and cut cost for eye motion in York Y Series inverter.

These is same like Toyota = Daikin vs Perodua = York
But both also have passo or Myvi right.

From here if you can't understand then go for google it out

Just noted that Daikin compressor using E-Scoll type & York compressor use DC Rotary type.

Got quoted $1500 for the new Panasonic inverter 1HP split unit.... include installation.

Panasonic aircon seems pricey compared to other models... hardly see them on sales as well.. sigh

i can confirm kimsim's statement. inverter will almost straight away produce savings of approx. 50% of electricity IF you dont underdimension the A/C (i.e. if the inverter doesnt run under full load), start/stop is not the main point btw.

You can savely assume that you will cut down electricity for A/C by 50% no matter the duration you on it for.

Given the tariff etc. you can quickly calculate how much you safe. Even if you plan to on just 3 hrs. per day, you safe  approx. 25 sen for 1 HP per day. I.e. annually you safe approx. 100 RM. Inverter aircon life is longer than normal aircon, you can assume 10 yrs easily. So price difference 500 RM - simple payback for 3 hrs usage: 5 yrs, simple savings in your pocket: 500 RM on top.

for 1 1/2 hours you still break even during the normal lifespan of the AC and you do good for the environment. If you never on the aircon, no need to buy also right. So I dont think you will use less than 1 1/2 hours in real life.

Normal usage is probably more like 6 hrs average, so simple payback is 2 1/2 yrs. so of course you should take inverter. Only ppl with too much money to waste wont buy an inverter. I am not that rich, so i buy inverter & safe.

For 24/7 your savings lets you break even after approx. 7 1/2 months. So the more you use, the more you profit from inverter. However for any usage (other than using it like display and never ever on!) you will safe with inverter in the long run.

It is not about how many hours.

It all depended on electricity tariff.

If non-inverter running full load at 0.75Kw (1 HP), means with 1 hour usage it takes up 0.75KwH.

While if using alternatively with inverter, it saves 30% (a typical use( due to running at below full speed, means
0.525KwH

1Kwh depended on the tariff rate, if using the tariff rate at more than 500KwH (average residential power consumption with common air-conds use)  one at 0.516

Means for every hour use, you save 0.155 cents.

So if inverter cost is Rm500 expensive than non-inverter, to recoup the cost.
Rm500/0.155 = 3225 hours of use.

if one day use 1 hour, it needs 3225 days of use to recoup the RM500 extra paid (set aside the noise/motor last longer issue), which means nearly need 9 years time, just for breakeven.
So if purely from money term consideration, inverter is not having any advantage.

If use 3 hours per day, means about 3 years
If use 8 hours per day means about 1 year.

So the math is quite simple, just work out accordingly.

One potential disadvantage of inverter, that based on my observation, compared to non-inverter is that there were cases (even in this forum) of PCB board that malfunction, which is need to control the variable running for DC motor of inverter, which non-inverter is not required this part. The board is not cheap, and warranty may only about 1 year. (I am not sure on this as each brand may different). So if spoil after warranty period, a potential costly part replacement may incurred, while non-inverter doesn't need to have this worry as we seldom hear of PCB board inside the blower unit spoilt, (may be not exposed to external rough environment, as well as it function quite basic as compared to inverter need to run at variable speed)

Also, as if the PCB board of inverter is placed with compressor DC motor, which means they are placed at outside, which exposed to external environment like heat, rain etc, which could potential reduce the life span of a PCB board.

i dont know what's your issue. you dont believe facts that's fine. however i am not in charge of your electric bill and other appliances. it's an undisputable fact that an inverter will be more efficient if not horridly underdimensioned. as such you will safe money in the long run. underdimensioned of course also applies to ridiculous temp settings. i really dont understand what the agressive discussion is about.

i have personally replaced all a/c with inverters and with identical temp & mode settings (28° dry mode - translates to approx. 24-25° room temperature) on identical sets panasonic standard / panasonic inverter a/c i have reduced the power consumption for the entire house by pretty much exactly 50% under otherwise same conditions. this does not account for the not reduced usage on pc, tv, hood, lights, fridges etc. so it's safe to say that actual savings is more than 50%. multiply your savings by the tarif rate and there you go. inverter *always* pays for itself unless you cram a too small unit into a room so its working to hard which would make the user - frankly said - an idiot.

you may also wire me 1000 RM for the explanation. i'll let you know my account details. since we are talking physics there is no way around it anyway so case closed. of course you can make it not save money by overloading so i wont take your results as proof of the saving statement not beeing true
