I live in Hickory, NC

I have a 1979 Bard 48HPQ2/B48EHQ Split Heat Pump Unit that appears the Blower Motor is having a hard time starting up. It seems to spin freely when I spin it, and if I help it spin, it will start up and sound and operate normally. It is a 1/2 HP unit Bard part number 8106-013 which is new Bard part number 8106-027 according to the Bard site. When it kicks on it sounds like a loud hum until I help it start.

Any idea on what needs to be done and what range of cost I am looking at?
