Tuga, it is always best to shut down any major loads before shutting down the generator. As a matter of fact, it is good to shut down all major loads such as AquaHot heating (AC) or air conditioners, then let the generator idle and cool down a couple of minutes before shutting it down.
I have a manual transfer switch so I can plug into shore power, remove the heavy loads, switch over to shore power and let the genset continue to idle. Have I ever switched over without killing the airs? YOU BET!! The air conditioners have a delay before they will let the compressor kick in after power has been removed so, YES, the blowers should come on as soon as the power is restored and 2-3 minutes later the compressors should start coming on.
