Air conditioner is not pushing air hard enough. Should I get a larger motor? Model number on the fan now is 7970-590

Is the motor you have now the original one on the unit?

If the coil is dirty the air can`t get through the coil and seems to not be blowing as hard, I`m saying this not knowing what kind of ac you have

Is the air filter clean? How about the fan blades?

Yes the motor is the original

It is an old coleman split system but the coils are clean

Is the air filter clean? How about the fan blades?
The air filter is out of the unit right now I'm going to pick up different filters today. The fan blades and condenser is clean
