Are you sure it's the compressor that's failing and your not loosing refridgerant from a leak? If no leak, check the belt tensioner and alignment your belt. Did you buy a rebuilt or new compressor?

If you take your car to a A/C service place, They draw a vacuum and check for leaks. If it checks out, they refill the system. This should have been done after the compressor has been replaced to evacuate the air.


That's what they are supposed to do and put a little oil in there to lube comp. Whoever did it last time must have flubbed the job and maybe even knew it, but sent you down the road Anyway. If it was done professionaly It should have lasted way longer. Try To go back and at minimal get a discount.


You could have just been unlucky & got a defective compressor. I work at NAPA & can safely say this does happen from time to time. Your mechanic must flush the A/C system, leak test the A/C system, replace the accumulator or receiver/ dryer, replace the orifice tube, then recharge the A/C system in order to do a compressor job correctly & not void the new compressor's warranty.

It's put under a vacuum to boil out any moisture because when water molecules touch refrigerant the water turns to ice and clogs the orifice/ txv, the vacuum has minimal to do with air.

So John, what about the question at hand? What's your professional opinion?

Defective compressor or as Jim said it wasn't installed properly, or as tom said it may have been a leak from the beginning misdiagnosed as a bad compressor and the leak never got fixed so the system is empty again. The answer has already been postedi was only imputing on the reason for vacuuming the system. The air gets pulled out completely within 5 seconds of the vacuum being applied. A vacuum needs to be applied for at least 15 minutes to boil and suck out the water molecules. Unboiled water molecules will also give a false leak reading under a vacuum. A few typos in there but the mobile page of cargirus won't let me fix them, there inputting was spelt wrong and spaces were missed.

And Mooney you are correct. There is a shop back in my hometown that intentionally messes stuff up and sends people on their way with more issues than when hey came in...
