Are we talking about the evaporator coils or the condensor coils.
If you are referring to the condesor coils then, there is no correleation between the condensor coil and air flow.
If you are referring tot he evaporator coils then yes, you may have flattened them out thus restricting airflow. Depending on how many layers of coil fins you bent, it will be a long and tedious task to straighten them out one by one. I would not attempt a fin comb.
