gone case. looks like you will be back to that AC shop in a few months

Is it possible to avoid damage if turn off the aircond when it runs out of gas?

can, thats what the sifu tell you, if aircon totally not cold, dont turn it on ,bring it to the workshop. its like an engine, you dont want to run an engine with no oil.

depend on brand type. can get OEM from 300+ to 600+. kalau ori, should be around 800+ to 900+.
oso need to know the cost of replacing condenser etc bila tukar compressor + workmanship. so should be around 900+- for oem... or more for ori...

lepas ganti compressor check tak lowest temp berapa dapat.?
if dapat 18c ..and the clutch magnet didnt cut off
aircon still have problem.

Ini I don't understand

Most car aircond I have seen have a pressure switch to to cut the compressor if refrigerant aka gas pressure is too low aka no gas/leaking.

But some smarty pants due to no bajet or just plain ignorant chose to temporarily bypass the pressure switch coz thinking still can pakai ma.... aircond shops welcome these people with warm hands

Also about the dissing of aircond flush technique in this forum. No wonder Msia cannot move ahead. It is supposedly a preventive maintenance, to change out the PAG according to maintenance schedule. But as with things here, the tech/shop fook it up by not having correct system (gas quatity and quality, PAG type) spec. Also with every flush, you're supposed to change out the filter/drier module as it would have accumulated enough dirts/moisture etc to warrant a change.

I have kept my aircond systems in 3 of my cars in excess of 400k km without a compressor change by doing aircond system flush through the years.

Yeah man.... if the tech did a good job, the supply air (cooled air at aircond outlets) should measure around 7-9c if everything (condenser, evaporator, gas amount, expansion valve etc) in good working condition.

Like most preventive maintenance routines, the idea behind AC flushing is sound in theory. However, in practice, it's often done with equipment that hasn’t been properly maintained. If the flushing machine is contaminated, it can introduce debris into an otherwise clean system—doing more harm than good. This is why some people would rather not take the risk. You never know how often workshops maintain their equipment.

Also, if the system is already dirty, that’s a red flag. The A/C system is sealed, so contamination usually points to a deeper issue, such as compressor failure. It's worth considering: you don’t routinely change the oil in your refrigerator or home air conditioner, because those systems remain sealed and clean under normal conditions.

Flush what? each flush is what RM150? the ac shop will charge you cos it's eXpEnSiVe MaChInE. you flush how many times already? condensor costs RM150

change condensor when spoilt is cheaper and less hassle

Can you teach me how should I do the flush? How frequent? What need to do? How I tell the mechanic?

Each you open aircon you car feel cool is it ?
have you wonder what temp is it ?
if you dont get lowest temp as possible.
you compressor magnet clutch wont cut at all.

what happend next ?

clutch magnet mati awal.

the perfect temp for cut off below 10c. we call this sejuk beku
if you just get 18c - 20c aircon got problem. Clutch wont ever never cut-off.

there a case everything change. pomen pening kepala.
gatal tangan change thermostat. terus sejuk beku

Ask yourself this question. Your fridge at home has been on since day 1 and the compressor keeps working until the end of time but why no company is telling you to service it by flushing the oil?

rm900 only also wan open rant?
K mostly rm20k level la. Your post really bring down the image of k level

i wonder if i bring this issue to my SC

I can't teach you how, but I can only share how I did it. Is that fine?

Since you have just repaired your system, it should be running fine I guess. So maintenance is up only a few years down the road. Immediate attention would be your cabin filter. Get it checked (DIY better, easy for proton).

How often? I don't set a schedule on doing flush coz I only have old cars, so things may fook up any moment. But on comparatively newer ones, I will flush it, say, every 4yrs or 100k km.

What need to do? For now just look around areas that you frequent and take note of any mech/aircond/accessories shop that have an aircon flushing machine. If possible don't be shy to go take a close look at the condition of the machine; meters still OK? filter at side/back looks well maintained? waste oil can still OK? most importantly asked the boss how much and what job scope? Then decide when time comes, where/which shop you want to try.

Aircond flush thread


Good luck

China compressor woh did you ask if get sanden original how much

theres a few differences btw car ac and fridge/house aircon

the car ones use o-rings for all the joints, while fridge and house aircond copper pipe are soldered together. so while both are supposedly sealed systems, the car one is less sealed and will leak gas/oil slowly over time. most important is that the o-rings harden and age with time so this is a bigger problem with old cars.

also the conditions a car compressor runs in are far harsher than a house fridge or aircon, sitting inside a hot engine bay and been exposed to road conditions.

how does PAG oil flush help with this? not very sure, but perhaps car compressor oil breakdown faster than household fridge. most important is I guess when you bring to do a system flush the machines also does a full vacuum, recharge and topup of your system oil and thats what really helps keeping the compressor in shape.

Do you regularly service your car aircond? I drove my car until 100,000km never serviced the aircond. The thing that leaked was the heatsink part. For car aircond that part call what? Fins?
