Compressor cycles on and off

if pressures are good and system is cooling stat probe in the evaporator is cycling. stat switch prevents the evaporator from freezing into a solid block of ice reducing air flow. Switch is located on the lower left side of the air box and has a temp probe going into the evaporator. What is the duct temp while cycling?

Exactly.
They HAVE to cycle, and it's the entire reason they have all that clutch hardware on them.:D
And, it sounds like it's cycling at about the right intervals.
I don't think you have a problem.
