A/C noise,..need advise

I noticed a whirr or a whine last week during very hot weather. Yesterday, noticed same noise along with the A/C working only intermittently (oh sh*t). The compressor was infact kicking in and out operation and especially when I would rev the engine. As engine speed increased, so did noise from the compressor area(I am only assuming it is the compressor). Today, during cooler weather, the A/C is working properly but still with some noise.

I will check pressures tonight, but am assuming they are OK. A/C is as cold today as ever, which is very cold. It's a great unit as long as it keeps working.

Had the compressor not been kicking in and out, I might assume the clutch, idler or pully. Now I wonder if the comp. is crapping out.

Any insight would be much appreciated.

Well I know that my compressor makes some noise and I can notice it if I listen for it. If it's making really loud noises that are worrisome you may want to have it checked out by an Authorized A/C Person. The Compressor will kick on and off that is it's nature however, it's only suppose to kick off if the pressure is too great or the cab is up to temperature.

Chuck, thanks for the reply.

I forgot to say that the noise I hear is unusual, it is not a normal noise that I have been hearing for 7 years. As far as kicking on/off, I didn't have my guages on. But I am pretty sure it was kicking out early, wasn't even long enough to cool the vent air.

After noticing same noises, I just went about town and was gone an hour. Cab cooled as normal. My last stop was the dealership to exhibit symptoms. The compressor was not making abnormal noise anymore!

Dealer theorized the clutch is getting old and operates normal after running awhile,...said to come back after more severe. Also said normal fix is to replace whole compressor,..oh come on.

If true,.. is replacing the clutch practical. I know the price difference btwn clutch and whole unit is significant.

Thanks

Yeah what a deal hey. Oh yeah you need a new Compressor...pullleeez Just sell me the clutch and I'll be on my way. Otherwise why tease us with putting the clutch on there....
Hope it works out for yah. Not the greatest thing to not have A/C this time of year.
