Hi all, first post!

Been getting an A/C noise. It almost sounds like a high pitched dry bearing sound. In fact when I first heard it, I laughed because my Millwright instincts thought it was the car in front of me with bad wheel bearings lol. Turns out it was me, doh.

It happens when the car is revving low (ex: stopped, out of gear ex, idling). Revving up makes it go away, or at least I can't hear it. I've also looked under the hood when this is happening and everything sound solid, no belt squeaks or the like. Air seems to be getting cold, I think, don't really remember how it was last year. Sound goes away when A/C is turned off.

I brought her in for the MM 9 service and got them to check out the A/C sound at around 55, 000Km; they were unable to find anything and documented as such. Brought it in a couple days ago as my clock is about 55, 700Km and want to get it addressed before the 60K warranty is up.

Talked to the Honda shop foreman, not very helpful. Even brought a USB stick with the video. Wasn't too interested in viewing it (his computer didn't have external speakers, but I'm sure someone does). Also said that it's documented that I brought it in before warranty is up "doesn't mean anything".

I've embedded a couple clips with the sound. You'll have to turn up the volume as my iPhone mic isn't that good.
Thanks.

My 2017 Hatchback A/C started making this same noise this spring. I'm just shy of 9,000 miles on it. A/C still works and blows cold air. I haven't had a chance to bring it to the dealer yet.

That sucks, let me know what happens at the dealership. Mine is less than enthusiastic to help.

i hear the same thing in my 2017 civic si. A sort of hissing, fluctuating between high pitch and low pitch, like an air leak that oscillates between small and large. getting some dealership maintenance tomorrow - ill update if i hear anything.

i was having the same A/C sounding like 4-5 month ago
the dealer tell me the fan in civic are making more noise then other car (WTF!!!), but they check it anyway.
they decide to change the blower and blower motor...after replacing the fan... they look over AC system and i was on route for a condenser and compressor replacement (leak and lost of refrigérant)

so after 2 week they manage to change the condenser and compressor (part are difficult to get i guess...lol ;))


after like 1-2 month it begin to heard the same ''bearing'' noise when the compressor is ''on'' or ''auto mode''...but before i was able to check with the dealer the winter was comming in canada....(lol)
and since the compressor dont start anymore i did not get anymore noise......the problem is that the AC work and it blow air a 4degC ...so the AC is ''working'' but that fucking noise is frustrating

in spring i'll be checking it again and bring it to dealer if the compressor noise is comming back


for god sake honda, you make great car but please change the compagny that make the condenser!!!! because a A/C replacement can cost more then a engine problem sometime!!!
