    I have been having this issue with my 2013 Model S since I have purchased my vehicle that I'd like to tap the TMC community about for advice.

    In my car, when the A/C runs there is an obtrusive "revving up" noise that starts when you turn on the A/C and stops the second you turn it off. You'll have to turn on then off the A/C about 2 or 3 times to have sound completely go away. It's tough to describe this sound but it is very noticeable in and out of the car and sounds like a turbine.

    Also my Model S has an extremely loud and obnoxious Fan noise that occurs most times when the A/C is running. This noise doesn't go away until the car is parked for about 10 or so seconds.

    Because of these two issues, it's really embarrassing pulling up beside someone at a red light because the noise is so ridiculous. Most days I just stop using the A/C completely and roll down the windows.

    I have asked my Service Center repeatedly about these noises and they continue to claim they're normal. They said they wrapped the A/C motor with noise dampener material but this hasn't done a thing. Am I crazy? I find this hard to believe and really think this is unacceptable for a $100,000+ car. My 1987 Chevy Chevette didn't sound this bad.

    My question to my TMC friends is, is this in fact normal? If not, any recommendations as to how to get the Service Center to acknowledge this or to rectify this issue?

    Same here. I had my 2014 at the SeC recently, due to IMHO excessive A/C noise - and was told "normal".

    My old 911 Porsche had the same fan noise, like an electric leaf blower, including blowing leaves all over the garage. That's just the cooling fan that is required to cool the car (or the A/C condenser in Teslas) when the car is stopped. I had one go out in my old 924 Porsche. I was fine while on the freeway but quickly overheated any time I had to stop.

    Many previous posters have been happy when the SvC was able to reroute the A/C compressor lines or fix A/C assembly errors. It may be that your A/C is marginally working but not very efficiently. Check through the threads and insist on a better check by your SvC. A fix might allow your A/C to work more efficiently and quietly.

    I made a recording with my phone while having the AC run (at a low setting) on a hot day. At the end (of the file) I turned the AC off: sound file (m4a). Standing next to the car it seems to roar much louder, than standing in front of it. In the cabin it is not that bad, there it is more of a rumble sound.
