Air conditioner coolant, also known as refrigerant, typically has a sweet or somewhat pungent odor, depending on its specific type. If there is a leak, it may emit a strong chemical smell, which can be unpleasant and potentially harmful. It's important to address any unusual odors promptly, as they may indicate a refrigerant leak or other issues within the air conditioning system. If you notice such smells, it's best to consult a professional for inspection and repair.
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.
