Aircond forming ice most of the time means gas is low.

Nothing to do with the air-cond itself generally.
Aircond is not manufactured to produce ice, rest assure.

I won't be surprise if it did happen.

Many condo and apartment nowadays has pre-fixed conceal piping for air-cond.
So ensure the spec of piping is suit to the air-cond needs before buying.

Last time, my house renovation contractor screw up the Astro conceal wiring, they loop the Astro cable like ordinary electricity looping, causing signal loss across all the point.

Workmanship is one area one always to look at and forget whenever there is issue on air-cond.

I have 4 Pana air-cond that being used for 4 years daily until now, none has issue (touch wood), until now.

But one poor workmanship in installation that not tilting enough, cause some minor water clog issue from time to time especially when dirty time.

Gas not enough is not because of the air-cond itself is good or not good. (unless it is air-cond internal piping issue, which generally less likely occur)
Gas not enough can be caused by leaking in between the piping, which is more related to workmanship issue.

So it is not fair to blame the air-cond disregard whatever brand.

Leaking also can give you cool air one.
It can result in freezing (not only cool )! if there is no enough gas (due to leaking).

Generally,
If it is installation error (piping leaking) is about contractor issue.
If it is air-cond issue/faulty then it is manufacturer warranty responsible.

You mean first time fixed already, and still happened?

Sometimes, it may better off to use third party or another experienced installer to check, as those installed one the unit one may not want to admit their mistake in installation (if there is),
or some lazy to check, (also they can't charge you if it is their fault in the first place, right?) ,as it may tedious and time consuming job to find out the leaking point.
Not meant installer is like that, as there are many good and responsible installer as well. Just speak with my experience before.

From my experience, (Had installed 3-4 brands before, and more than 20 unit in the past including Pana latest), seldom air-cond itself got problem, most of the time, if there is problem, very often come from installation issue/problem.
