Welcome to the forum its a great place to get your questions answered. They don't come with any sort of soft start that I'm aware of. The heavy draw from an AC is at startup and can be as high as three times the running amps. The steady draw you were seeing was the running amps not the starting amps. As units get older they tend to draw more amps.
