Noisy Heat Pump


Looking for ideas to quiet a noisy Bryant outside Heat Pump unit. We have a newly built home that came with a contractor grade heat pump. Initially they installed the outside compressor unit directly in front of one of the kitchen windows. After 6 months of shake, rattle and roll I made the sub-contractor move it to a blank wall location. It still made a racket maybe even worse. I was able to quiet it somewhat using rubber grommets and rubber strips to dampen the outside shroud from excessive vibration. However the compressor, still transfers a terrible surging vibration to the brick veneer wall where the pipes that are connected to the attic air handler unit enter the house. I have had the H&A sub out 3 times and it still sounds like a wood chipper grinding hardwood and gravel. Called Bryant and they offered Zero help. Help. Thanks Ross

Is it practical to remount it on a pad?

It is currently mounted on a Plastic or fiber glass fake concrete look alike base. It is obviously very rid. I had wondered if outside units were shipped from the factory with the 4 compressor mounting bolts screwed tight to prevent damage during shipment. I asked the sub if the bolts needed to be loosened when the unit was installed to gain maximum damping from the rubber mounts. I got no answer. Where would I get a pad and what should it be made of ?
