Lifespan on a car aircon system?

[Hummin]

How long should a car aircon last in Thailand? Do they change the compressor if the aircon unit go down? 

 

5 years old 90 000km changed aircon unit, and did not check if they changed the compressor unit.  Soon 6 years 102 000km changed the compressor. 

 

All mandatory services done at Mitsubushi.

Nissan navara 2010, 250K kilometers, not changed anything but the cabin filters.

I'm pretty sure that changing the compressor at a certain mileage is mandatory in any service manual
