An air conditioner should not smell like smoke when turned on (or when turned off). I would have to suspect that the electrical insulation is burning.

A smell coming from a reverse cycle air conditioner may be a signal that the filter needs to be cleaned. A smell like engine exhaust might be present if the air conditioner motor is in need of repair.

Cats are drawn to the fish smell because their sense of smell is different that ours. Their sense of smell is about 15 times greater than ours. They like the fish smell because they love to eat fish.
