A/C routine maitenance?

[YYC]

in the airconditioning system of car, compressor is the only place with moving piston and shaft, and it takes a lot of pressure and heat, and located just beside the engine, so do you think it is a maintenance-free component? My car compressor had not been serviced for a very very long time until one time I ask the air-cond expert to open it up and there is zero oil in it!

My friend has replied me since the father and himself own the air cond service shop.

He said don't listen to those who in forum said need to service compressor oil.
There are no need for preventive maintenance just the filter itself.
If your air cond doesn't feel cold, turn it off immediately. If it keeps running, whole set will be totaled.

Told you also, right? Even my own regular mechanic tell me not to touch the system if every thing running fine....

Well then how come compressor oil gets so dark just like engine oil after long period of usage? I'm not an aircon service man, but if I look at the darknes of old compressor oil, then I just cannot imagine to keep using it.

If aircon is not cold, not necessarily due to compressor or the oil but most often due to gas leakage. Aircon can still be cold enough even when already starting to run harshly (making humming noises). Now that's when you know you're probably too late already to rescue your compressor. I experienced that before when I also ignored changing the compressor oil (even when the car mileage was still <100k km). Ever since that, I change compressor oil regularly and I never had such problem again.

Anyway, it's up to you what do you think it's the best thing to do coz it's your money after all. But for me I will keep doing what I've done all this while based on my own experiences and I don't mine the cost of those routine ac maintenance including changing the compressor oil.

If have gas leak, the system needs repair and once you re-gas then need to refill the oil already.
Well, all in all, also depends on luck. My VR in use for 14 years, changed 1 recon compressor before only and car is 23 years old dy. My Hyundai also in use for 11 years, also repair the compressor once only. Some Wira owners I know change coil every 2 years, compressor every 3 years and so on...

Exactly, an AC compressor is like a small engine with pistons & shaft which are subject to pressures and heat, so the oil would not last forever. When I changed the compressor oil on my Mark X shortly after I bought it, the oil is totally dark grey like mud! Compare that with the new oil which is clear color, it's scary.

Well I don't want to rely on luck, especially if it's an expensive car with most probably equally expensive AC parts. I had compressor failure below 100k mileage of the car and had to fork out a substantial amount relative to my income level at the time. That's why I'd rather do routine maintenance.

In a way it is better for you to do maintenance since your parts are costly. My parts are relatively cheaper therefore the maintenance cost added up can be my repair cost or more...:hmmmm:

Last time it happened over 15yrs ago to my 1991 & 1996 Lancer only. Even so at that time I cringed already coz I did not have much spare money. But maybe also if you drive a lot (say >20k km/yr), then can be rather costly. I drive about 15-20k km/yr, last time was only 10k km/yr.

If I don't use air-cond regularly? Will it slow down the process?
Or the oil still deteriorate after years?

in theory,the oil will last longer because the piston is not moving as the clutch is not engaged.

another cause for quicker compressor failure is frequent run at high speed.
this will cause strong shock to the compressor everytime the clutch kicks in.
i guess u gues have heard of aircond clutch explode into few pieces and fly through the bonet.
my uncle have 1st hand exp on his vios...and no,the compressor was not a recond unit.
it was new with the car.car is only serviced at Toyota.mikeage was below 150k km when it happen.

He always cruised at high speed.the clutch punch a hole through the hood,through the front windscreen and landed near the handbrake lever.and...no, i am not making this up.

Though I heard of a/c compressor explosion during servicing, I doubt car speed contributes to a/c compressor explosion on the road (at least not a direct and near cause). There could be something within the compressor system, things like internal failure, electrical short, contaminants etc causing excessive pressure. I definitely need further reading on the topic.

That is why when I do pick up in my VR I off the compressor....

Got one time I rev quite high, the high pressure hose burst.....

Guess u need a BOV on the ac system oso...hahah
On the high pressure hose,is it the same as hydraulic hose?
If yes then i do believe sending it for fixing is cheaper as i discover when changing a pwr steering hose.

If air con system then need to send to repair because still need to vacuum and re charge in the gas....

Dear all,
Good day!Service manual indicated compressor oil interval 30k mile ages , lubricate type HFCS-1 and volume at 480-520g . Is it gas volume? How about oil type n volume? Any adv?thanks

 

[lewcheeheng]

Honda has came out aircon services interval in 30k mileage ncompulsary by doing this if u would like to hv the 5 years warranty. Be told by sc -Honda that the cost about RM 300++, service all parts , they even bright the machinery to do the services!

Aircon filter of inspira , cost RM 187.50 , so expensive man ...compared with honda civic 2014, it only about RM 100++ if not remember wrong ; air filter cost RM 80++, whereas Inspira cost u RM 149.50. Suck blood man......some more fuel filter RM 432...I've be services my car recently spent RM 1,000+, including this fuel filter.

wth man. I tot Inspira being Proton will have a lot of aftermarket.
I strongly believe filter(s) have aftermarket. Filton brand of sorts...

That is sc price maybe?

 

[lewcheeheng]

Correct. The price of air filter is under proton but Mitsubishi brand n made in japan. There hv lot aftermarket , such as K&N , cost about RM280, reusable , however no good for our engin for long term. So I better stay at original with low flow air types.

Correction, it made in Germany. But who care! As long it suited to our type , even made in Malaysia, provided quality is good.

Sorry, the replacement is made in japan, original from Germany.

30k service for rm300.
Let say u travelled 100k km ler year thats rm900++ a year.
Which means after five years it will be rm4500++.
Worth it?
Up to u really.If your car has cheap part then i dont think its worth it.

If u worry about the price so much then dont send your car to the sc.send it outside.I wont worry much if i were u as your inspira is actually a mitsubishi.

Insipra's parts are that expensive? RM432 for a fuel filter is even more costly than my V6's RM150 and the f**king Diamond water replacement filters, generic just half the price. Must be rich to drive an inspira.

Fuh! I can change fuel filter 10 times for mine.....
