Hello sir! Your problem is in the outside a/c unit. "relay coil" its stuck in a/c run mode. That is why every time you turn on the heat or ac from the thermostat it always running.( and sometimes during the winter months and even when the furnace isn't on that outside ac unit will come on ) i see that you have shut the ac off at the breaker box. You need to go out outside to the ac unit and go inside the back case remove the cover and change the relay coil. You can do it yourself or have a qualified technician do it for you. But rest assured that is your problem . You can call me at 313 978-3717 my name is dwayne alexander and my email is [email protected].
