I know people have said this is normal, but i am getting to the point where I think its not normal anymore. I am of course speaking of the hissing noise of the a/c compressor letting out air or whatever it is. In my car it is really loud and it happened like once every 2 to 3 minutes this morning. I guess it does it everytime the a/c goes on or off depending on what temperture you have the climate control set to. Its really lound and sounds really shitty in a "luxury" automobile. I have never driven another car that has this annoying sound and everytime i take someone in my car they ask "what is that sound?". Is this really normal? and if it is, is there any way to minimize it? I just find it really hard to believe that they would intentionally make a car that makes that hissing sound when they could make it not make the hissing sound.

It does not sound normal to me. Mine makes no sound at all. I'd get it checked out. BTW looks like otherwise you've got a great car, red 6 speeder!

russianDude

mine does make hissing sound as well, I belive its normal in Honda / Acura vehicles...

zoltanh

uhm, so some do and some dont?

My A/c makes a high pitched whine whenever it kicks in. it's not very loud, but it is noticeable. I'm wondering whether i should take it in under warranty...Anyone else?

AMorgCLS

I believe the A/C compressor is covered under the warranty, if you still have one.

zoltanh

Yes it is, but is this normal for a cl? Last time i was at the dealer they claimed its normal but i find it hard to belive that it is.

Don't know... I'd say it's normal. I had 2 different CL's. An auto & the 6 speed & they both made all sorts of noise with the AC on. We in FL run it almost all year so maybe we notice it more. If you have an AEM intake it will amplify the noises.

Also if you know Honda you will know that almost all Honda cars have loud AC systems.

zoltanh

If its normal then I hate this car and im getting something else. Ive had nothing but problems since i got this car 3 months ago and its only got 28k miles on it.

zoltanh

So i realized it only does it when i am driving the car not when i am just standing still in it. This morning it made the sound like every 2 minutes while i was driving. I know the air is supposed to cut out at WOT but, i think it might be cutting out like 1/2 of the time i press the accelerator even though it was never WOT. Any ideas?

I'll pay close attention to mine today and see if I get the same thing you are talking about since we are in the same area. I've never really noticed anything before but the may be because my last car was a Civic w/ 150k and that thing made all kinds of noises. Was like driving a wind sock compared to the CL

N.O.6speed

mine does that same thing. It isnt really loud, though.

What temp do you have it set at? Does the AC even get cold?

zoltanh

Its set at 72 degrees and yes it is cold.

Is it just the hissing sounds or is the compressor turning off & on every few minutes.

jherb

Was just out for about a 30 mins, had A/C set at 68 (outside temp 89) and didn't hear any hissing coming from the compressor and the A/C was blowing cold. If I were you I would get it checked out. Someone correct me if I'm wrong but could he have build up in the condenser that could be causing the compressor to work harder?

zoltanh

Thanks i made an appointment to at the dealership to have it checked out on tuesday. I hope they dont pull they old "thats normal"

Okay, I think I know what you're talking about..

When I drive my 2002 TL, with climate control on, sometimes I'll hear a "pssssssssssss" sound and sometimes, condesation will come through the vents (this is normal, has happened in all 6 of my Honda vehicles and none ever had problems with A/C)... it's not a loud noise, and it's the sound of the A/C compressor working after it's been shutoff.

Try this: Set your temp at 60 and drive around. Do you hear the noise? If you don't, then I'd say what your car is doing is entirely normal. At the min 60 and max 90 the climate control won't regulate temperature, it will just operate at full force. So if it only does it when it's 61+ then it's normal operation of the A/C compressor.

It has never bothered me because it truly isn't that loud. Do you hear it OVER the radio?

zoltanh

Yes, if i listen to the radio at normal volume, i can hear the a/c sound over the radio.

Allout

The sound your talking about is probably the expansion valve. My 2003 TL-S was loud but our TL-P and CL-S both have pretty quiet valves. As long as the function of the A/C is fine, it's probably normal.

03CoupeV6

Yeah I'm fairly certain that it is a normal function.

I ran my car this morning & I still say it normal. Mine does a phssssssssssssss every few minutes in the full auto mode. If I switch to non auto & left the temp at 60 the noise was gone. Is it loud? A little but I don't here it over the stereo.

Well today on the way to the beach i tested it like 10 diffrent ways and came up with these conclusions:

#1 When i dont have it on auto and I change the temperture from 60 to 80, the temperture of the air coming out of the vent feels the same, cold but not ice cold.
#2 It does the hissing weather i put it on 60 and auto or 60 and not auto
#3 It doesnt seem to do it when I am at a stop light or I am stopped, only when I am driving

Either way i think something is messed up, I should definatly notice a diffrence from when I set the air to 60 or 80 even wheather i have it on auto or not.

How many miles on it? Have you changed the AC filters? It could be low on refrigerant. Or might be some other problem. Let us know what the dealer says.

zoltanh

Well i got it back yesterday and they said it was a little low on freon so they put some more in there and they put some dye through it to see if there was a leak and there wasnt. They claimed the noise is normal but it was made worse by the car being low on freon. I only drove with the air on for like 5 minitues, but it still made the noise. Maybe not as loud but it still does it so...... if it gets annoying again i guess ill take it back.
