Why is my HVAC running but not blowing air?
If your air handler is running but not blowing air, there are two likely scenarios; either a broken AC blower belt or an issue with the motor itself. If the air handler is humming or buzzing, but not making the mechanical sounds of a motor running, you're most likely talking about an issue with the motor itself.
