Topup gas today (47th month,~yr4)..actually realized also had a previous gas topup at 25th month also.

Service guy explained gas topup ~every 2yrs can be expected..unlike fridge which is sealed system, aircon has nut connections at compressor and FCUs, ie prone to leaks over time.
Everything was related to workmanship, a better job done, even 5 to 10 yrs still not an issue.

Just depend how is the exprience when they connections the nuts, some they worried to fall down with compressor together rather than quickly done and didn't check with bubble test before to handing over.

So the future has many troubleshoot to be solve.
