What is the size of your evap and do you have good access to measure face velocities without disturbing the airlfo. If big and yes - hire a velocity grid to measure the face velocity and take 12 to 100 readings depending on coil size, then average out your velocities and muliply by the area this will give you airflo rate. Also take the static pressure readings from before and after the coil. If you can't do this then hire a ballancing technician to do it for you.
