Aircon oil renewal necessary?

[Lightzvs]

Is the aircon oil renewal necessary at 80k service?

[Speddevil]

If air-con still new and is in working condition, no need to touch anything.

[Lightzvs]

It was recommended by workshop while doing 80k major service. :| Dont know considered whether is it necessary through.

I would have the compressor oil replaced...same logic as replacing engine oil. Lubrication oil will thin-out over time and have to be replaced. Why wait for the compressor to breakdown? Will you do the same for engine and gearbox.....nothing wrong, don't do anything to it?

 

I really don't understand the double standard many treat their engine and the aircon compressor.

Ya ! Totally agree .....u need to change the oil....but at the same time ...u also need to do up the flushing of the system .The reason for flushing the A/C system is to remove oil and contamination (metal chips) which might prematurely spoils your compressor. Somemore a new compressor is not cheap....esp for conti.

HVAC system should only be serviced by AC technicians. Don't go to a general car workshop to do it. They recommend this and that and then outsource it to an AC tech that is servicing several car workshops. If you want real AC advice for your HVAC, see a specialized AC workshop.

True enuff....MK can do it?

Thanks Bro for your advice

Mark Cool definitely can and so is Precision Engineering which is recommended by Apollo.

 

All the mechanics and workshops recommend this and that want sales. There was a time I went to Mark Cool and they told me not to service when nothing is wrong. Compressors aren't cheap but a car's HVAC is pretty much self contained.

 

About the compressor's oil, it is just the same as your manual gearbox oil. It doesn't face combustion products, it is completely sealed and most of them last for bizillion miles. You only need to check the level. Top up when needed. Not change it.

...travel almost every week pass mark cool.

The place is convenient at least for me. Hope they dont move out

I thought Manual gearoil was recommended to change at interval by workshop due to the metal rust or what..

[Speddevil]

Bro where is it located?

[Lightzvs]

if it is completely sealed, then no need to renew the oil.

 

BTW: can top up ourselves meh?

This is the recommendation from my a/c specialist in Melb

 

"Servicing of a vehicle air conditioner is recommended every 12 months. This is due to the fact that most systems will lose gas slowly through hoses, O/rings and spinning shaft seal etc. Moisture can also be absorbed through hoses and gas loss and filters can block with debris.

 

An air conditioning service involves connecting service gauges and running air conditioning to check pressure, system performance, etc. Degassing and evacuating system if required and regassing to correct gas level. We also check hoses for possible wear or leakage, belt tension, condition of compressor. Condenser filter etc. and overall performance. Then the system is fully leak tested and service sticker is applied indicating gas type, oil type and service filter due dates."
