Corolla TS Hybrid 1.8 sound when ac turns on, normal?

[Snake91]

Corolla TS Hybrid 1.8  loud sound when i turn ac on? Owners of same type, same sound? Compressor already replaced, but same sound.

Yes normal. 
Usually when ac compressor is loaded the noise is louder and gets quieter after some time. Also a noisy ac compressor is a sign of low gas. Of you haven’t regas your ac ever and the car is 4 years old or more it is a good idea to do so.

Why the compressor needed replacement at that age?

But that’s the normal air conditioning compressor sound of any Toyota hybrid. 
Who were they? A Toyota dealer service technicians? 
This ac sounds about like any other hybrid ac. 
You can listen those on other cars in dealerships or YouTube. They all sounds exactly the same. 
There is nothing to worry.

Maybe in UK, we have Rav4 Hybrid and Yaris Hybrid, and i heard that noise first time in my Corolla. Toyota dealer in Slovenia "Štajerski avtodom" replaced it. It looks like they didnt hear that noise before and they sell Toyota cars.

But its true that my Corolla its the only one with electric compressor.

Any Toyota hybrid air con compressor is feed by the high voltage Battery and they sound exactly the same. Prius, Auris, Yaris, rav4, Camry etc 

The air conditioning compressor can be tested for faults with simple diagnostic obd 2 adapter like Carista, for your peace of mind. 
CARISTA OBD- bluetooth Scanner and App: Diagnostics, Customizations, Service Procedures and Live Data for your vehicle https://amzn.eu/d/01gqWiub
The only time when compressor becomes noisier is when the weather is very hot outside and the car been exposed at direct sunlight, there is sensor built into the top of dashboard who sends information to the ac ECU’s that manages the work of the ac.
Another time when these becomes noisier is when they get low on gas and oil, then they lose some cooling power and start to be noisier. Re gas and they become quieter again and cool of cabin faster with blowing colder air. 
I don’t know your personal case and why you went to the dealer with questions about ac noise and if they tried to find a fault where actually there were no faults and they replaced an ac compressor without need of , or your car had have a faulty compressor as once in a while defective parts or workmanship can happen?

AC was working very good, it was only loud, all tests was ok, and it was cooling ok, but they replaced it anyway.

And you still have the same noise, They should have not touch it at first place.

The danger of accepting there is a fault when in fact, there is no fault. A dangerous way of dealing with a fault is to fire the parts cannon, customer has a noise, fits parts, customer still says there is a noise, something else must be faulty, fire more parts at it, absolute nonsense

So what should i do? Aceept that that is normal sound or press on dealership that something else is faulty?

You have to establish if it is noisy, is it any more noisy than another car of the same make/model? If they are the same, there is no fault, no point in fitting parts if it is a standard noise. If they think it is more noisy, then investigate what the noise is. There are times when people think there car is noisy, or operates outside what they think is normal, if it the same as another model of the same type and they all the same then there is no fault, you cannot fix what does not need fixing
