   I don't know if there is more vibration with an icf wall than any other,but why attach to the wall? Mine are mounted on stands a foot or so away from the building specifically to avoid the problem.

   Nick,
   I would assume that lower frequencies, if they are present, would be transmitted much better through the structure. Unless you have specific sound dampening between the mounts and the concrete, I would also assume that there is the possibility that the compressor and or unit might have a frequency or resonant frequency, which operate in the lower ranges. I can hear my neighbors compressor that is close to 1000 feet away though; I can also tell if my electric resistance boiler is running based on the AC hum, so don't take my word for it.

   Yes, I'm considering mounting it on a separate pad instead of wall mounting it for this reason -- I just wanted to see if someone had experience because it seems like some people say theirs is just fine with a wall mount and rubber vibration damper (although I haven't seen anything specific about ICFs). If it were just for A/C it wouldn't be an issue but I would want to mount about 5 feet up to keep it away from the snow so that is just more complicated doing a ground mount as we would need to build up some sort of structure to place it on.
