    Carrier Heatpump Vibrating

    Im working on a 3 ton Carrier HP/AHU installed in 2015. Had a leak at the liquid line dryer. Repaired the leak. Got called back for a no heat, thought the compressor wasn’t pumping so we swapped out the compressor. Worked for a day or two and got called back again. System has a stuck reversing valve, so we replaced it and the system is switching properly. However when running in heating mode the evaluation coil vibrates so bad the filter door rattled off. System has a lot of oil in it. Could there be too much oil from the old compressor that was stuck in the evap? Any help would be appreciated

    You sure its not overcharged?

    Excess oil? That could be.

    Also Carrier makes a couple of items made to quiet noisy outdoor units. There's split bolts to go under the compressor, which I've had so-so luck with. There's a rubber piece they sell that they call a mass damper which works very well, absorbs far more noise than you'd think by looking at it, its a heavy rubber sleeve that you put on the suction line. Sometimes even some rubber waffle pads under the condenser are an improvement.

    It’s not heating. We’ve thought about pulling everything out and flushing the coils and recharging the system. Line set is really short.
    Pressures were 102 Suction/330head
