Is the air filter a high efficiency type? They will restrict up to 400 cfm of air flow,that is nearly 1 ton of capacity.

Is the filter tough to remove while the unit is running? this is an obstruction to your unit if so, try a cheapo $1 see through type for AC mode. As mentioned the AC coil being clean is critical  and overlooked too often.

If it has not been chemically cleaned it is likely dirty.

Is the larger copper tube at the AC unit cold when the units operating?  It should be cold and wet as a can of beer will be, if not you may be low on refrigerant or as noted tired unit.
