How to properly test the furnace blower?

If the blower is operating and the filters are clean check to see if the blower is loose on the shaft.
Make sure you look at all the ducts in the attic to see if any have fallen apart or if any of them are loose.

If the motor is up to speed you should have good air flow.
Is there ice on the evaporator coil?
