        just to hide the spamquest, a reminder that this is the time to clean your exterior a/c coils of crud with the garden hose, spraying WITH the openings of the fins so you don't fold them over and lose cooling.

        if your motor has oil ports, pull out the disconnect bar near the system, take off the fan cover, and work 15-20 drops of non-detergent oil into each oil port. push the covers back in if you have 'em when done. sewing machine oil will work if you have nothing else, SAE 20 turbine oil would be ideal. the "zoom spout" oiler sold in notions and sewing stores is 10-weight turbine oil.

        if you can't find it, log on to mcmastercarr.com, search "turbine oil," and get a quart. and a lubrication syringe.

        They always seem to say these compressor and fan motors are sealed...and no way to oil them. What do you think?

        ah, yes, "lifetime lubrication"... when the lube is gone, the lifetime is over.

        most small motors in HVAC fan service do still have oil ports, even 1/10 HP units in those motel room package heat/cool wall units. some have little plastic plugs in the oil ports, some don't. worth pulling the service switch and feeling around the top edge of the casing side to see if you find one of those little hollow dimples. if so, there is a corresponding one at the bottom of the motor.

        usual recommendation of the 1/6-1/4 size used in both a/c outside compressors and in many furnace squirrel-cage blowers is 15 to 20 drops of #20 non-detergent.

        as for "sealed" motors... if you can see any felt from the wick holding the Oilite porous bronze bearing at each end, you can carefully drip and wait 10-12 drops into those felts. probably about a 2 beverage process. you don't want to goop over them and walk away, the oil will gum up and glue the motor shaft.
