Usually the scams are condemning the compressor when it only needs a capacitor. Overcharging for an evaporator cleaning is a new one. Perhaps there is more to it. For that price he should have given you a much more detailed explanation. Obviously you should get a second opinion, even if it is over the phone.
Also there are different schools of thought about chemicals on coils, especially acid. A seriously neglected evaporator coil may need an acid cleaning but that is unusual for a residence. If they do an acid wash then it would be time consuming as it would require much time flushing with water afterwards.
