I did a little research and it seams the air conditioning in the model S is quit noisy by default. I have a 2013 S85. Sounds like a jet when first started up on a very hot day on max fan/cool. SC was going to order one of their noise blankets but from what I read it barely helps. New mounts are available too....same result. My concern is that I feel a somewhat high frequency vibration in the pedals and the steering wheel from the compressor. Is this normal? Feel like my hands are getting a massage. Goes away immediately when I shut off the AC.
