Before all this inflation denso compressor RM 800 denso cooling coil RM 280 cool gear condenser RM 120 from dealer price original equipment price very tough

Gas refill RM 100 , dashboard remover RM 150 labour or depends on workshop

Thing not included if your high pressure and low pressure hose leaking or not if both RM 150

Vavle is not included denso RM 65

So you kira kira that the price in between

Unless everything you go for cool gear except compressor only option are denso

If you want best effect on cooling upgrade your radiator fan to lagi best variant which is the 1.5 litres engine variant if your already 1.5 litres engine variant the fan can just ignore it which also whole set cost RM 150

Try not to buy over online if you have no experience usually original equipment do have thicker material compare to 3rd party if you found online seller cheaper price they simply just put denso but the equipment itself not a denso or coolgear

my 11 year old working on field vehicle myvi daily travel at least 150km here and there now mostly yearly will doing compressor flush plus replace dryer for RM 200 due to mostly on field use even yearly flush I can still seeing significant grey residue possible overheating and wear and tear nothing to blame just hope can last longer haha

If you only use for daily go and back is okay go for cool gear except compressor without choice since all reconditioned compressor really depends on luck some after 3 months warranty started to failed then need to doing flush all over again or replaced whole set again so is a waste of money

Normal operation those oil will not mix with the gas. Noted oil leakage into the gas system.

Many reason. Your car not moving, outside air not helping cooling the car. System not cool enough - need to check gas pressure. If gas ok, need to check fan and compressor.

Usually refrigerant light yellow ish color then some with green ish dye color for leak check if leaking

If compressor overheating causing from condenser not fast enough eject heat or engine bay too much heat or the weather too hot both senario also causing overheating that the refrigerant above boiling point no longer proper lubricant the compressor starting scratching metal then slowly all this metal residue go through cooling coil and condenser then slowly dryer like a filter become sludged black lost the ability to trap residue more and more residue back to compressor
Which giving compressor faster failure

Even now yearly I do flush my AC plus dryer replacement still can seeing significant grey on dryer like 20%

My first gen stock compressor last me 8 year haha after that replace whole fan and bracket replace the lagi best 1.5 litres variant after that not much issue no matter how hot the weather still blowing cold air

Just yearly will doing vacuum and dryer replacement not sure is this considered flush or not I guess not haha

Yearly dryer replacement still can seeing significant grey residue trap on dryer maybe climate change is the one to blame more and more equipment failed too easily 😂

The chemical part are flushing the the high and low pressure hose
Since compressor coil and condenser are new item if they go and flush it go and sue them hahaha

Edit ops sorry didn't know cooling coil is not included

The aircond died suddenly while driving. Only hot air.
Pomen said compressor died.
And gas also turned black.

In fact im the one asked is it need to do flushing to clean the black oil and the answer was "no point do flushing somemore if flushing not properly may cause leaking"

Thats why im surprised billed for flushing. And surprised the pipes not changed coz i clearly heard pomen said need to change whole set due to black oil.
Pomen got simply point "nah changed set" and i have no idea what exactly "set" is..
I only know for sure compressor was changed. Condensor not sure cot cant see it

Just change condenser + topup gas - RM600 all inclusive

RM2k is normal for everything.

Yeah. I heard people upgrade to the bigger fan motor from newer unit. They also have a shroud that covers the compressor so engine heat will not heat up the compressor. The dryer is common problem that is not serviced. That time 10 years not serviced at all!!!! Thats why the air that blew out is foggy like smoke. I think i might service it annually or 2 years once. The last service i did was like 5 years ago. Only recently few months the coil leaked and can smell some kind of chemical smell in the cabin.

Appreciate if you could advise me.

Honda City is coming to 4 years soon, mileage < 30k km. I know aircon compressor needs clean oil but have always been reluctant to meddle with the system due to kena brainwashed - car aircon, if no problem don't touch it.

Is changing compressor oil a straightforward job? I'm most worried about the pomen not knowing the exact oil and refrigerant volumes required, main hentam jer.

30k km for 4 year wow only go wet market and balik kampung use?

Well most ac guy checking pressure and refrigerant volume during refill they have no proper measurements other than that aka experience agak agak hahaha

So far as I know if you done any disassemble from stock the AC seem like more issue than before , if your AC still blowing cold air without weirdo smell stick with it usually can last 8 year minimum

I guess only manufacture vehicle assembly have a proper measurements how much refrigerant volume needed

Last time house got waja never service before 8 year later coil leaking during disassemble no sign of grey residue at all

Then my working vehicle myvi gen 1 stock AC also last 8 year due to magnet clutch failure during replacement no sign of grey residue too only replace condenser dryer and compressor , but the workshop recommend me drain the old refrigerant and dryer replacement yearly can improve liability for the compressor , after that 2nd year i go visit the workshop during refrigerant drain and dryer replacement can see a grey residue significant compare to stock

So this is made me wonder all the workshop AC guy only base on experience too much refrigerant too much work for compressor too less oil leading more wear and tear never done in service center maybe my other vehicle should give it a try on service center see if the compressor can as good as stock

For now if your AC have no issue stick with it first 😆

I'm also concerned about contamination, you know, using dirty container to measure oil or when their vacuum devices are contaminated with previous customers' dirty compressor oil/refrigerant.

As for official service centre, maybe it's worth to ask if they do it in-house or simply drive the car to be serviced by outside aircon guy.

Because most workshop AC guy always telling me compressor do not need service or every 2 year due to they say AC refrigerant and oil won't become grey or black color unless compressor start to failed service is needed when coil are dirty haha

Then I ask what causing start to failed the answer is not enough refrigerant , not enough oil , condenser dryer dirty , condenser issue, condenser fin fall off or blocked

Problem is after i replace the compressor 2nd year start can see a grey residue advice me to change coil and condenser I say do i need change compressor they say no need but advice to use newer radiator fan from lagi best

After I bought all this from delaer replace everything including expansion valve except compressor 3rd year i go back as workshop advice drain old refrigerant and compressor oil by vacuum without need machine then i do see my condenser dryer have grey residue compare to stock

Haiz this is why make me wonder the AC guy either not enough refrigerant or not enough compressor oil which lead to my compressor easily more wear and tear compare to stock 8 year without any sign of grey residue Or climate change haha too hot that the main cause 🤣😂

Your condenser dryer is a filter should be able to do the job trap the residue and contamination dryer also capture any moisture from the refrigerant this is why also important to vacuum before refill any refrigerant which can causing over pressure just refill without vacuum haha

Official SC I ask before cost me RM 4k+ to replace all just a myvi... hahahaha this is the only reason i go out replace it , I thinking before drive to sc for a refrigerant flush and drain not sure they do it or not maybe during free want to visit SC and ask

Aircond is most complicated and most simple system at the same time

my experienced with old myvi (2009) ac, the 1st time its not cold after 8years bcoz of punctured top hose for the condenser.
replaced it, top gas oil, its cold already.
2nd time, magnetic clutch broken (the rubber holding the magnetic clutch plate disintegrated). diy replaced, working good again.
3rd time , not cold when stop, fan motor weak. upgraded with bigger motor fan set (halfcut). good already.

then gave the myvi to brother. ac not cold. he went topup gas and oil, good cold back again..

When the owner cheapskate and want to diagnose and fix which is the issue then it is complicated.
When the owner can spend to change whole A/C system new then it will be simple..

Thats the whole problem with this automobile aircond industry, most of them don't want to invest in proper tools in their line of work. Chicken and egg situation. They think using pressure gauge alone will do la, but they forgot if they recharge gas at hot noon (36c) is different than thunderstorm rainy days (25c).

Also they love to skip the vacuuming process b4 recharge part, just to save 15mins.

Thats why i prefer (actually insist, nowadays) to only go to shop that invests in an automated flushing/recovery/charging machine. If there is no fault in the system aka periodic flushing/exchanging of PAG, then I get to save on filter/drier cost. Mind alredy set to do this on every car that I own every 4yrs if equipped with cabin filter or 2 yrs without cabin filter.

As for the info on proper "volume" of gas/refrigerant, it is already stated by the car manufacturer on a sticker under the bonnet door. It is always stated in gram/weight coz pressure changes with ambient temperature. At least true for japanese/korean cars that I own.

As for PAG volume to refill, got to refer to manufacturers spec.

If you have been servicing the car in SC for the first 3 years (due to warranty), the AC service is included in their schedule. AC service usually includes changing oil. This is when they plug the flushing machine into the AC and let it run for an hour. Check back your receipts.

If you don't mind paying more, just send the car to SC for all services. If anything is spoil, let them tell you what is the problem and then fix it outside workshop (cheaper). I have been doing this for my previous car (Honda City) and the car was in immaculate condition (engine, gearbox, ac) when I sold it on the 8th year.

I don't see this in maintenance schedule nor have I seen it mentioned in invoice. My car is fully maintained by official SC.

Yeah this is why most people prefer if AC without issue don't service it once service too late to regret haha

Well since I'm already washed my hair wet I guess have to stick with it until i sold or recycle the vehicle haha
