If you are not facing any problems then i will advise you to leave it as it is.
These local AC mechanics don't use proper equipment hence causing several problems.
You can get the evaporator cleaned without disturbing the rest of the system. For doing this just blower motor would be taken of.

Please tell me what's the cost of full AC service and what exactly do they do in AC service?
