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.
