Mr. Duct Cleaner has specially designed equipment that can clean outside as well as inside systems.  We do more than just wipe down or spray off the outside of the unit.  We thoroughly clean your condensing unit, freeing it from debris and contaminants and allowing the motor to work more efficiently.  Yes, you could clean a bit off by yourself, without calling us, but just because you can do it doesn’t mean you can do it properly or that you should be the one doing it at all.  Call the experts and leave the cleaning to us.
