On a delivery vehicle it is a working condition
A driver who gets in and out of a vehicle thirty times a day is not experiencing air conditioning the way a commuter does.
A commuter gets in once, the cabin cools over ten minutes, and it stays cool. A delivery driver opens the door, lets all of that out, works outside in the heat, and gets back in to a cabin that has to start again. Repeat that all day and the system never gets ahead, which is before anything is wrong with it.
Which means a system that is even slightly down on capacity produces a materially worse working day on that kind of route than it would on any other. It is also the kind of thing people do not report, because it does not feel like a fault.
For a fleet it is worth treating as an equipment item rather than a comfort one, and putting it on the spring list alongside everything else. A fault found in April is a repair; in July it is a repair and a wait, because everybody discovers theirs in the same week.
What helps on that kind of route
Running on recirculation once the cabin is down, which gives the system already-cooled air to work with rather than outside air each time.
Keeping the cabin filter clean, since reduced airflow presents as weak cooling and is not a cooling fault.
Parking in shade where there is a choice, which sounds trivial and is the difference between the system starting level and starting behind.
What usually goes wrong
The national A/C service page covers the common faults and why recharging without finding the leak is temporary.
