So if you do build an elevated structure for your OD unit, don't even tie it to your house... resonance will be transmitted.

Finished installing my Mitsubishi heat pump 2 weeks ago and it has been running nicely ever since. The industrial rubber vibration isolation feet I installed on the outdoor unit are very effective and I can't hear or feel any vibration or resonance in the house even when standing inside the house next to the wall with the outdoor unit running 2 feet away on the other side of the wall.
