This is false. They're not supposed to leak. "Replenish gas reserves" is not a regularly scheduled maintenance item. In fact it's illegal for a technician to add refrigerant more than once without identifying and repairing the source of the leak. Unless you did something stupid like tried to install a split system yourself.

If your unit leaks refrigerant it needs to be repaired. This is not normal.

“Not supposed to” is a very weak condition in manufacturing these days.

ICE cars aren't supposed to explode nor are EVs supposed to burst into flames via inextinguishable battery fires.

But sometimes they do.

We don't use this outlier data to refer to them as conflagrations-on-wheels and assert it's a normal function of the device just to strengthen our biased case.

Sure but battery fires are still a problem that needs to be fixed and not ignored. Also, even though it doesn’t happen often, when it does the results can be catastrophic. So it is a reasonable concern.

You have to deal with battery fires but they're not a climate issue.
