I had previously asked for help about the vibration coming from our Climate Master Tranquility 27 geothermal unit. Because our water comes up under the unit, out unit has to be above ground and is attached to our wall. The manual calls for it to sit on a neoprene pad to help with vibration and noise. But come to find out, the contrator put a 3 inch Air Pad Condensor base pad under it which is extremely light and hollow. I don't see that the condensor base pad has anything to do with vibration or noise and is used to set equipment on. Please tell me what kind of pad is needed to help with the vibration and noise that is coming from the unit as our wall is vibrating and the noise is fairly loud. Do we really need the neoprene instead of the condensor base pad? I am wondering if the contractor tried to pull something over on us.
