Is acson good? Quality and after sales?
I was quoted for acson for normal 2.5hp with installation at rm2500. Does the price expensive?

I was quoted as well for daikin r22 inverter with installation at rm1800. Does it expensive?

Having a lot of money doesn't mean he knows everything. Do you even know how cold actually 25oC is? There is a range of combination of temperature, humidity and air movement which is known as the thermal comfort zone, in which human perceive themselves to be comfortable. 25oC is usually the upper limit. In HVAC design, that approximates the max temperature you can go in Summer before it is deemed uncomfortable. On the other hand, 20oC is the minimum temperature you set for heating in Winter before things are deemed too cold for comfort.

To be fair I absolutely agree with your earlier contention that passive cooling and better structural design reduces the need for active regulation via air conditioning. However I cannot abide by the fact that you dismiss setting 25oC as a good practice. It *is* the norm (it should be even higher if we really want to save on carbon emissions). To use another car analogy, you don't floor the pedal if you are just intending to drive at 80kmh

The whole point of all the technological advances in HVAC and environmental design such as inverters etc is that you would want to adjust your living environment so it is comfortable with the minimum drain on resources.
It's not just about the money here.

It's just absolutely wrong to even justify setting 18 or 19 or even 20oC in our Malaysian climate as it is extremely difficult to achieve. To be honest with you I think the majority of Malaysians are ignorant about how air-conditioning is supposed work. An expat friend of mind once remarked how silly and ironic it was to see Malaysians set 18-19oC in their office thermostat and yet come to work clad in sweaters and jackets, complaining it was "too cold".

FYI until recently I lived in a 3 storey house with 8 air-conditioners, (including 2 energy-sucking 2.5 and 2HP cassette units) and my monthly bill was rarely above RM170. That was because I minimized usage of the air-conditioning to just a few hours at night, not seeing the need to blast it on 24x7 and tried my best to use electricity saving devices like inverter fridges, LED lighting etc. It's no point bragging about electricity costing RM700-800 and being able to afford paying for it. It think it's downright shameful nothing more is done to lower it.

just my 2 cents'

York is under daikin company and sharing same technology from daikin low budget design and cut cost for without eye motion in York Y Series inverter.

These is same like Toyota = Daikin
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.

Well, does brand matters? I doubt so. The quality and easiness of getting repair and service are more important.
Since you take Proton vs Toyota, guess you need to think twice before saying Toyota is good. My friend just bought a Vios J recently and he regret on buying it. The rattling noise is same like his 16 year old Wira.
For air cond it is the same, I don't bother if it is made from China, more important is the service center I can get within 10 minutes from my house. This is what we shall look at.
There's no point on getting a brand which the service center are limited. This will take longer time to get it repaired and the work quality will be unknown also.
Like car CD player, why I choose Pioneer and not Alpine? Just simple, Pioneer has > 10 service centers in Malaysia while Alpine only has one service center in KL.

Daikin owns OYL. OYL owns York, Ascon and several other brands. Google.

Inverter works on DC current.
So have to convert our Tenaga AC current to DC current before use. The lost due to conversion is between 5 to 10%

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

Wooohooo.. installed my 1st air cond brand Daikin R410a !! lolz...
the compressor damn big... bigger than Panasonic which my neighbour have it...

Share for you tip on Daikin FTKD model was used R22 gas only would not faster cooling like R410A model as FTKS.

Don't buy wrong, below sample for R22 gas only.

Due to my condo layout, my air-con guys said each of the air-con need to attach with a small pump,
so the drip water is 'powerful' and route to balcony from master room

separate insulate much better to avoid water drip on wall or outside diameter 

Ok to be wait and see how survive on next few yrs of R22 last.

from buyer is always prefer new one, from seller is always prefer old gas, due to more stocks up or more lobang to grab cheaper R22 from regular supplier right 

lol... wait i am be the aircon "RESELLER" then i would realise from your... 

not lah... i am still more interested of my part of aircon hobbies from before. 

sorry i am not part of daikin user here.. 

from my previous A/C hitachi, panasonic will slightly delay only and ME or york don't this issue.

but do not after power on and suddenly stop it, once you turn on again for delay compressor must be have their reason to protected Swing Type and oil runs.

looks good
the wall plug there is for what purpose?
would be easier in my case to put all wiring/piping go thought master bedroom to ourside
if that's the case, must make plaster ceiling, but might make the room looks 'shorter' in terms of height as the room is 9ft tall

means it act as aircon point?
both work well
but i guess conceal would be easier
cut the wall, slot the pipes in, then patch it back, all done in one go

will take the cornice idea into consideration

same thing with this?


or need to have this switch + wall plug?
