The blower motor for my furnace/central air sounds labored
while running and there is an occasional screech. Bearings?

Sealed...no oil cups or ports. That was the first thing I
looked for.

Hmm,
Next thing is to check if the starting cap. is going South.
Since they're not that expensive, just replace.

he said "labored and occasional screech"

does that sound like a starting problem ??????
why dont we throw a new thermostat and put some freon in it too while were at
it
oh! and dont forget to wash the coils too ,

you dont make anymore sense here than you do over in alt.hvac

Note to OP, yes it sounds like bearings , direct drive i assume since you said
it has no oil ports ,

Direct drive or belt drive? If the latter take off the belt and check
the blower for free turning. If the bearings are bad there are
standard replacements that are easily done. For direct drive there are
severasl online sources for whatever new component you need. HTH

Starting cap? Why would a residential air handler be
equiped with a start capacitor? A standard squirrel
cage blower motor usually has only a run capacitor.
The newer high tech units have a very expensive
variable speed motor.

Wouldn't hurt to mention age of unit ...

Check for oil aperture on motor. Oil if found.

Some of the older "non-oilable" blower motors were oilable. I nursed
my old Carrier (actually a Bryant) for 20 years.

I can GUARANTEE you, it aint the starting capacitor ,
