Maybe, how's that for a concrete answer?
In general no, however often times some type of spacer between unit and concrete can make the unit operation quieter.
There are square pads that can be placed between the unit and pad to absorb vibrations but they can also tend to shift and one will pop out from under the unit. A composite pad will eliminate that problem.
Why do you ask?
There could be some other reasons like raising the unit for easier connections or if the concrete is not level it may be an easier way to level the unit for example.

Heat Pump? If so and you live in a relatively cold snowy state, elevate unit off pad for better water drainage during defrost.

If that is code then yes it is required. Now we can argue all day on the validity of the reason for it but if required The Powers That Be win.

Spread the weight around on the concrete so it doesn't crack.
I bet it is to help eliminate vibration into the foundation.
A town north requires all units be on a bracket on the house as I get it. Some places don't have enough exposed foundation to mount a bracket. Go figure.
Key words “if that is code”, some inspectors will make up their own codes and when you ask them to show you where it says that, they can’t. Not worth the argument for some things but other times the argument is warranted.
