A/C seems a bit loud/vibrates

    Granted it is winter but in South Florida it is never winter... And I don't enjoy smelling the other cars fumes so I raise the windows in traffic and turn on the A/C. I have only had my MS85 for 6 days now, but it seems like the A/C is not as quiet as when I first turned it on 5 days ago. The car also tends to vibrate a bit when it is on... is this normal?

    I've had A/C components replaced once due to extensive vibrations. So strong that the front seat passengers could feel the vibrations in the floor boards. There was also a very dramatic "hamster wheel" squeak as the fan slowed to a stop when shutting the car off. Thanks to the replacement, there's less noise and vibration now, but it's still quite noticeable (more the noise than the vibration). The SC told us that there is a redesign in the works and we're on the list for this "A/C 2.0," whatever that entails, when the redesign is complete.

    The vibration is pretty normal (mine isn't nearly as bad as Rockster's). However, there are two tricks:

    1) Start the a/c at a higher than normal temperature so that it doesn't come on full blast when starting.

    2) When you have excessive vibration, just turn it off and then right back on again. That seems to quiet it down.

    Mine will do it right after starting a drive. It goes through "steps" where the humming goes up in pitch and volume, then down again. After about 2 minutes it stops and there's no noise or vibration no matter how hard the AC has to work.

    I checked with the SC and they say mine can be fixed by installing a "AC compressor blanket". I'm scheduled to have it done mid January.

    I had the blanket and new bracket installed last week. Completely fixed this issue.

    I am wondering if this is what I experienced today. When leaving my desk to go home, I flipped on the app and saw the inside cabin was 108 degrees. I vented the sunroof and turned on climate control. 7 minutes later I was in the car and could hear a very, very loud hum over the stereo. I could feel strong vibration on the brake pedal and in the steering wheel. It threw me off and I was worried, but I figured maybe the AC was working overtime. It weakened over the next 10 minutes before finally dissipating. During that time, I also saw my energy usage was over 600 Wh/mile. It was 91 outdoors at the time. I have to take the car into service in the morning anyway, so I thought I would ask them about it.

    For me it "mostly" fixed it. I still get some noise and vibration when it spools up high, but not as bad as before the retrofit.

    The best thing with the A/ works fast! It might be noisy, but it works well.
    The blanket does reduce the noise of the A/C. However, you will still notice when the A/C is on because there is no engine noise to block out the sound.
    I'm happy with the blanket fix.
