    the fan blade my be going bad. sometimes when the blade loosens from the hub it can make loud noises during start up and shut down.

    recommend having a tech come out to take a look at it

    is there not another contractor in your area that could be of assitance?

    i had the rep from the wholesaler look and listen to it . I was the one that installed it . The noise on shut down is the compressor and that make me worry that it wont last. I worked for a service company for years and am not a pro on a c if i had a problem i would ask one of the bosses both were journeyman

    Thanks for the reply

    is not unusual for scroll compressors to make a noise during shut down. if york has a compressor blanket available for that model, it can help reduce the noise if it is of nuissance.

    Because a fan can spin freely, there is no hard start kit for a fractional hp fan motor.

    Am I correct in assuming your fan motor and blade are generic replacement parts, and not the correct OE parts? Is that why a wholesaler is involved?

    Short of replacing the motor and blade with the correct part, we can't make a further diagnosis without being there.

    Is your compressor elliptical or cylindrical?

    Excessive noise is a valid warranty code (at least for compressors)
    It's not rocket-science...

    It's electromechanical thermodynamic engineering
