A/c fan seeming very loud

[bigroo42]

So I have had my car for a few days and I notice when my ac kicks on a noticeable buzz/hum, if you will coming from near the frunk. It gets better when the climate control slows down and gears down a bit. I videoed it but not sure if I can upload it here or not.

Is this normal? Or should I be worried?

Can't upload it.... Too large. :/

I think this is pretty “normal”. Mine does this as well

I also think it’s normal. Mine sounded like it was about to take off into orbit today. I will say it might be software related because I don’t think it’s always been this loud.

It's the AC compressor and it's normal. You can't hear it inside the car with the blower on auto.

What makes you think Elon is not trying to launch your car into orbit? We all know he put one out there already

Yep same here, and it doesn't always seems to be related to heat. Car can be in our cool garage, open the door, and it will sound like its about to do a vertical takeoff. We also leave the A/C on AUTO. Would be nice if they could get that tamed a bit.

You shouldn't be able to hear it inside the car. It also can give deaf people an alert. Noise makers may soon be required for new EVs.

I can definitely hear the compressor start and stop while in the car. Start up and stop are louder.
I’m not talking about the interior fan.

It can definitely be heard from the inside. Very load and annoying. Of course it doesn't do this at the service station.

are you concerned about the sound from inside or outside the car?

The A/C compressor is quite loud when running full speed. I can hear it inside the car, and the car vibrates noticeably when its running at high speed. If you reduce the fan speed the compressor will generally run at lower speed and not be as loud, but also wont cool as well.

All things considered, its quieter than the A/C in most cars, but since its basically the only thing making noise its kinda annoying when it runs flat out. I'd like them to have a 'quiet' mode that limits the max fan speed and compressor speed so its not super loud in auto when you first get in. The noise is really just intrinsic to the design. There's nothing wrong with your car, and the service center cant fix it. You can manually set the fan speed low and that's about it.

I also don’t have an issue with the sound. I just wanted to make sure it wasn’t just mine.

fair trade for not having an engine running and vibrating

I have the same period loud hum in my MS75D. I have had the car since June 2017 and I do not remember it being this loud. It is very noticeable inside the car. I had a Tesla mobile tech come to the house and after running a number of tests he assured me that the car was fine and the noise was normal in hot, humid weather.

 

[BZM3]

my family has a 3, S and X. When its a particularly hot and humid day and you are just getting in the car, the air compressor does occasionally run very loud and a vibration can be felt on the floor and pedals. Since this is consistent throughout all of the 3 models we have, i'm assuming this is all very normal. and it only lasts a few moments. if you dont want to hear your AC/compressor run in overdrive, i'd recommend precooling it a few minutes before you get in and by the time you get to the car it will be stabilized....

@BZM3 +1

I'm pretty sure this is one of those instances of "I only notice because there's no engine noise". My previous car had a noticeable A/C compressor noise when it was on full blast as well, but it was somewhat masked by the engine itself.

 

[ngogas]

Normal. Mine is pretty loud. I wouldn’t worry about it tell it blows hot air when it’s meant for cool.

I notice the load fans/compressor when I forget to pre-cool the car. It really ramps up to high power trying to rapidly cool the cabin temps, which it does. I fixed the problem by "always" pre-cooling the car, expect to those times I forget.
