Default Electrical issue HVAC

This has been going oin for two years.

My AC works fine and heater works fine. The issue is the transition from one to the other. If I run the AC during the day and switch to heat, all is well. If I switch from heat to AC, the outside unit trips the breaker. If I try to flip the breaker on, it just trips again. The only way I can go from heat to AC, is to turn the system OFF, flip the breaker on, then turn the system back on. So strange. Once I do this ONE TIME, the AC will cycle just fine every time. If I run the heater again, I have to repeat these steps.

Heater cycles fine
AC cycles fine
AC to heat, works fine
Heat to AC trips the breaker
Shut down, set breaker, restart...all good.
