Noisy Aircon

Postby chrislloydie » Thu May 10, 2007 4:10 pm

I've asked this before but got no real answer.

When I switch my Aircon on I can hear it click on from outside the car, but then it makes a constant whooshing noise which is clearly audible inside. I have driven numerous cars with aircon and none have ever made this noise.

Anybody elses make noise and was it normal or did you get it fixed?

The click you hear is the compressor turning on and the whoosing noise is the aircon coling fan - its like an additional radiator cooling fan. If you look under the bonnet you wil see them side by side.

I am surprised you can hear it in the car as I don't remember hearing it whne I had either of mine, except when I had a window down :?

It's definitely audible inside the car. If you switch aircon off the noise goes away, switch back on and the noise reappears. Never known any other aircon to make this noise.

Anybody else have noisy aircon or is yours silent?

Mine does it as well Chris

Previous megane (mk1) also used to do it, but my dad's Megane II 1.9dCi does not? and my previous Laguna did not, luck of the draw I'd say.
I've questioned my dealer about it and they've said that some do and some don't? Not exactly what I wanted to hear, I've got used to it now. I find it's worse with the centre dash vents open.

The air con unit in my office makes a similar noise as well.

Ho hum! :?

Not sure about Chris's but mine make's a metalic wooshing noise as the engine revs rise and fall. Mainly noticeable at around 2000-2500rpm

Yeah sounds exactly the same mate. Noise increases with rev rise. Oh well I guess I'll just have to put up with it. I will mention it next time I'm at dealers though just so if anything does go wrong its noted.

Just another noise to add to the squeaky dash, steering knock, noisy engine and whiney auto gearbox. :cry:

My 2003 Meg does exactly the same. Sometimes the noise is completely gone and then suddenly it comes back. Never had this problem in my previous car (Clio II).

Two different dealers have checked everything on hte airco (compressor, belts, pressure of the system, etc.) but said that every airco makes a little bit of noise. Some make less and some make more noise. You can't do anything about it they said, except replace the whole lott.... :cry:
