    I have the same heatpump and I hear the same noise you are talking about. It replaced a 12 SEER Lennox AC that may have measured at a higher decibel level, but the lower pitch made it less noticeable. I have not asked the installer if this is normal, I just assumed it was.

    Noise is definately coming from condenser fan motor. Tech said that he did not think this is normal. They are going to change motor tomorrow. I hope this quiets it down. Don't think that I could live with it this way.

There is also a Quiet Shift Option available that is not in manual. Am I missing something?
    Is it not available because I am in Comfort Mode. I am assuming aux heat is coming on to maintain output temperature. I have figured out that fan speed changes to maintain output temperature but I think that I would like to have heat pump work a little longer before aux. heat comes on.

    Thanks
    I found this option in Fan Coil Setup instead of Heat pump Setup. Manual not as new as thermostat I quess. Still have not found out what Quiet Shift is.

    Can any Carrier guys comment on what the noise level if any that the condenser fan should be making on a 25hna heatpump? They are coming on Thursday to change it but Tech did not seem real confident that it would make a difference.

    Also do you know what the Quiet Shift setting in Heat Pump Setup is?

    Thanks
