I went to a site yesterday were they have 12 Daikin VRV2 units. 2 of them are making a lot of noise,whitch comes from the compressors.whe lifted the complete units and put rubber matting underneed(3cm thick).
its better, but the sound is now moving throu the pipes. i now there are flexible connectors but do they take the sound away as well??

all tips welcome,
