Prius (2010-12) :: Air Conditioner Compressor Noise
Jul 29, 2014
I have a 2013 Prius with few miles. It seems like the air conditioner compressor makes a very loud humming noise. It's a little annoying inside, but outside it is really loud. I know it is running off an electric motor and I expect that to make some noise, but this seems excessive. Is this normal? Also, the compressor keeps running all the time. I thought they were supposed to cycle on and off. It seems like all air conditioning compressors do this to conserve energy, even a house air conditioning unit.

Just put my car in for it's first year's service(20,000 km). I made an observation to the service tech that during warm weather, there is a noticeable rattling whirring sound.
During testing, they were able to compare my car with another and confirmed the noise to be from the air-con compressor.

101,400 miles on car. Started noticing about 2 weeks ago, at idle, and as pickup up speed, a whining noise coming from the engine bay. It has gotten a little worse, so I started trouble shooting.
Basically, at idle, its somewhat annoying, but as you hit 20-30mph it can be more annoying if the radio is off or at low level. If Im sitting there in park, and its whining away, all it takes is me cutting the A/C knob to OFF, and then quiet as a mouse.
So, other than the compressor going bad, I can't see anything else related? I always hate when AC problems show up, they are never cheap....

I am inquiring what the proper way to use the A/C would be. Here in Sacramento my car will be hot as hell when I get in the car. I am still figuring out the best way to cool the car down. How does the "LO" compare with the temperature gauge? I am noticing that when I use the 65 instead of the LO that the A/C feels cooler, but that could be just me.

I have a 2009 VW Tiguan SE with about 85K on it. Yesterday driving to work the alternator/ac belt broke, after replacing the belt the AC compressor will not turn on. The AC was running fine up until the belt broke, so far I have checked all the fuses and the codes, no bad fuses and no codes. I read in the manual about a compressor shaft overload protection but it doesn't go into detail what this is or how to reset it. I could imagine that since the belt broke while the AC was on the system could think there is an issue with the compressor and shut it off but I can't figure out what to check or how to reset it. The AC system was checked a few months ago and has been producing cold air so I don't think there is a coolant level issue.

I have a 97 Mazda and I notice that the air compressor never shuts off unless I turn the A/C off. I have checked the relay and it is fine. What other control is keeping the compressor clutch from releasing?

l have a 2000 model accent and the air conditioner compressor clutch is not engaging . you press the 'AC 'button and the indicator comes on when a fan speed is selected which l am sure is the correct operation.l checked for 12 volts at the coil terminals of the relay and there is no 12 volts.l shorted the switch contacts of AC relay and the compressor did engage so the wiring from the relay base to the the compressor clutch is ok. l also checked the contacts of the 'AC' switch itself and it seems to be ok. l haven't had much luck with sorting out the wiring from the switch to the relay as l do not have a wiring diagram.

1996 Mazda Protege air conditioner died today in the lovely 2nd week of Kansas heat wave of over 100 degrees each day. Was replaced in 2006.
What should be the approximate cost of the parts and labor to replace? Is it normal to have died after 8 years? It was a reconditioned one.

My Chevrolet 1992 Caprice Air conditioner is chilling but the compressor doesn't disengage when reach the right temperature inside cabin... There seems to be a temperature control or a sensor and I don't know where is it...

Got a 06 F250 V8 Gas. Went to turn AC on the other week & got warm air out vents. Put 1 can of 134 in & the gauge on the "kit" said it was in the green. It was working last summer. You can turn the compressor "face" so it's not locked up, but it's not kicking in. Swapped the replay with another one & the 10a fuse in the fusebox under the steering wheel is good. Is that the only ones? I find it hard to believe that it's something serious. We did change the belt a few weeks ago & I was hoping that we had pulled a wire loose. The vacuum line that plugs into the heater hoses is plugged in.

I have had my 2011 Prius for about half a year. Lately, I noticed a louder than normal AC compressor. It is very loud, and I have driven it in hot weather before so I think I know what it normally sounds like.

I've bought a used Prius 2010 V this winter and didn't use AC until summer. Now that it's summer I have noticed that AC compressor is pretty loud (esp. when turned on for a few seconds) - loud enough that it can be heard even when engine is running but faintly. Some vibration from compressor also can be felt when not moving (parked) and touching brake pedal. Noise is about as loud as mobile phone left on vibrate on a wooden desk, but higher pitch and a bit muffled, or as loud as a climate control fan on max setting. Would that be normal?

We have a 2010 Hyundai Accent, with low miles (10,000), and the A/C Compressor is making a "growling" noise. The only way to explain the noise is when you hear a human try to immiate the sound of a dog growling. That's exactly what it sounds like.
First thing in the morning it doesn't make the noise to much, but as you drive for a bit you will start to hear it. Sometimes it's really loud, sometimes quieter. When you shut the A/C off, it will continue for a few seconds then stop.
The service department told me it was the compressor and it is, "pretty normal on the cars." How is that normal though? It sounds awful.

My wife has a 2010 Explorer 4.0 with 46000 miles on it. Yesterday the compressor started making a grinding noise when you turn the defrost on. It's only when the clutch kicks in. I'm hoping its something simple but, I fear its not.

I purchased a used 2013 Prius C last fall (currently its ticking 33000 miles). That time the weather was cold and did not need the A/C that much. As the summer progresses, I am hearing a loud noise coming out from the engine bay as I turn on the A/C. Here is an YouTube link for the noise.....

Quick back story, bought the car a year ago, seller told me it was in an accident and the radiator was replaced. He let me know that the discharge AC hose was missing and that the other hose was disconnected. I also noticed that the low pressure cap is missing. I recently ordered and installed the discharge hose with the intention of filling the system later.
I have always noticed a noise/vibration coming from the passenger side when braking at low speeds. I havent noticed at higher speeds but maybe there is more road noise. The best I can describe the noise is that is sounds like a compressor running. I have a hunch it's the AC compressor and might be related to the regenerative braking, but I am no expert.

Just got a new 2010 Prius III with 78,000 miles. I recently have had the car out when its been warming up outside and I noticed that when the AC is on every now and then it will make (in my opinion) a very loud electrical noise. I took it to the Toyota dealership and they said that the noise is normal (I even showed the person that checked my car in this exact video) however I question if they really heard the noise I was complaining about because it doesn't always do it (which is another reason I wonder if it isn't normal). Keep in mind my phone is close to the source of the noise so with the hood closed its not as loud but its still VERY noticeable.

As I am driving my 2009 Azera, every five or ten minutes there is a soft to moderately loud clicking (or clacking) noise for a second or two. I have tried pinpointing the location but it is difficult. When I have other people in the car, we each think the sound is coming from somewhat different locations.
The noise is loudest and most frequent when it is hot and the AC is running, so I am guessing it is associated with the cooling system. I have taken the car in twice. The second time, the service manager said she had read the Sonata was making some clicking noises in the moon roof, so she had my Azerra's moon roof serviced. That didn't work.

My 2013 Chevy Equinox has 30,000 miles. When the car runs with the air conditioner on, it has a whining sound that goes off when the A.C. is turned off. I have taken it to my local dealer several times, and they say that the whining is normal for this vehicle. They also say that Chevrolet will not authorize a repair under warranty for this problem.

I recently (~2 weeks ago) had the air conditioner's compressor replaced in my 2003 Subaru Outback. Now, when I turn it on, it makes several loud noises like what an elephant would sound like. As well as noises that sound like a bubble popping in the "bubble blast/bubble popper" smart phone games. Every time it makes one of these noises, it also chugs the vehicle a little bit. If I turn it off, then back on again and set it to the lowest fan setting, it eventually stops.
Of course when I called the place where I had the compressor replaced, and brought it back in to them, it did not do it for them. I'm just glad that it FINALLY did it today for my husband to hear. That way I don't have to hear about it being chalked up to "pregnancy brain imagination". It originally started happening only if I had the air conditioner already on when I turned the vehicle on. Now it has progressed to every time the air is turned on in general. What could be happening?
