AC Needs Recharging?
Iíve seen some threads on here about loud AC compressors, but none seem to end up with a solid resolution, so I figured Iíd ask myself.
About 2-3 weeks ago, suddenly, I noticed that with the AC set to a fairly cold temperature, or at least a temperature much lower than the outside temp (if you live in Chicago, you know itís been sporadically very hot here this month) - I could hear a loud groaning sound that correlated exactly with RPMs and went away with the AC off.
Now, we did go from what must have been the longest winter in history (almost no spring to speak of, temps went from consistent 30-50 degrees to 70-80 almost overnight) straight to summer, so itís been a while since Iíve used the AC before the last few weeks. However, it never did this before. And, frankly, even during some of the warmer days in April & May when I was certainly using the AC (although not as heavily) - I did not hear anything at all. This seems to have been a sudden occurrence.
I have also thought lately that the AC could blow colder - I hadnít thought this before, but today, while driving around, even with the system set to max AC, it seems like I remember it being much colder even a year ago.
Iím wondering (and hoping) that this means it might simply need a recharge? As far as I know, this car hasnít ever had one, and itís a decade old now...so seems reasonable that this might be the case. However, the loud compressor also often seems to be a sign of failure, although it seems strange that for a purely mechanical part, it would suddenly become so loud and not gradually become worse & worse.
Will probably buy a recharge kit just to see, hoping that takes care of it. Thanks.
