Hi guys, wanna check do you all always turn the main switch of your cassette aircon off?

My aircon guy told me that those 32A switch is not durable, he recommend me to have it directly to the circuit breaker and just leave it on. He also said for cassette aircon I should not cut the power to the aircon immediately after I turn off the aircon because the water pump need to pump out the water, only can turn off the main switch after 10-20min.

Wow just notice now Aircon also so many model.
Daikin inverter alone got Smarto, FTKM, FTKU, FTKP, FTKF.
