i only change the cabin filter. heatsink part = condenser

i regret doing a flush, because at about 80K after that the condenser leaked. dunno if it was related. whatever I ended up changing the condenser and compressor for rm900 altogether.

so dont do flushing? but should we change the compressor oil?

Normal wear and tear kot? Mine also leaked around that mileage.

dunno. they showed the leak (dunk the condensor in water tub). I had washed the condenser before DIY. itchy hands kut.

can get at part shop ori not more than rm1k

Leaking and topping up gas isn’t a big issue. But like I mentioned earlier. if there’s a leak, you’ll already notice a drop in A/C performance. That’s the time to replace the O-rings or affected parts and not get sidetracked doing unnecessary flushes. This is exactly why some people complain their A/C stops being cold again just a few months after servicing because the root cause (like a leaking seal) wasn’t fixed.

Yes, car A/C systems operate in harsher conditions, but let’s not forget: your fridge compressor runs 24/7, non-stop. Most cars are driven just an hour or two a day. My old fridge is over 15 years old and still working fine.

In the end, as long as the system is sealed and properly maintained, the PAG oil inside can easily outlast the car. The so-called "oil degradation" usually only happens because the compressor is already wearing out due to age or high mileage — not because the oil randomly breaks down.

if you ask me, if ac still cold, no funny humming noises just leave it alone. But always good to check for leaks in the system.

flushing or changing compressor oil requires the machine and sometimes on a busy weekend i see a long queue of cars going through the same machine. Do i want that machine to go anywhere near my ac system? Probably not.

yes market price with standard warranty period from china

changed mine and it works until i sold my car after 3 years

sometime don't be too calculative with foreman, think about the long run

Probably hit a stone while driving. Condenser fins are very very thin and fragile.

That's why old honest mechanic always say ac no issue dont kacau. Because in this case, you will need to open up the AC system to replace the condenser, then you need to do a compulsory round of flush/vacuum/recharge. Then you realized all that money you spent for flushing before is pointless.

Deswai when the fancy SC recommend me service aircond every X km I didn't do because the manual said SC supposed to check the condition see whether need to service or not. Then I became Senaxis loyal customer, they never recommend me service aircond.

So cheap??? 900 for both compressor and condenser

Axia. Not proton

need to attend to abnormal noise from magnetic clutch.
if it is slipping, it will overheated and spoil the compressor shaft seal and caused leaking.

car ac problem always starts with leaking + poor workmanship.

if lines is containminated with black powder from compressor, flushing the whole system before fitting with new compressor is necesssary.

flushing also make sure oil is correctly metered.

my compressor no clutch one. if there's any noise, i guess a new compressor replacement.

yes, once system is opened need to do all that.

3 months is nth, but almost all oem 3 months warranty, my car aircond has leaking issue, every time top up can last about 6 months, you see in this case if i change the new OEM one, the warranty is only 3 months but if after 6 months it start leaking again how do i know if they really changed the parts.
