Sure, you could take it to a shop and let them do it. They make these tools for a reason. It is very difficult to get air out of some of these systems do to the design. Some cars it will just work itself out by driving and topping off when cold. There is also the possibility that a previous overheating has caused head gasket damage and that will continue to release combustion gasses into the cooling system faster than you can take the air out.
