noisy a/c compressor?

Mine sounds like that. ('14, 6500 miles).

 

Yikes, dude. Get it fixed before it implodes and puts metal through the system. It's a no brainer for you since you're still under warranty. Lucky lol

 

why replace it if it's working? might last 5 more years.

 

The actual tech at the dealer (not just any service person) said it was going bad. I assume they have seen this before, although maybe not this new.

 

There's a point to be made either way. Catastrophic failure is very destructive, but simple slop in the compressor can persist for a long time before failure. I'd say if it seems to be getting noticeably worse over a short period of time, better get it fixed.

 

I agree. I didn't hear mine develop the noise from one day to the next, but it was definitely normal in the past week

 

don't forget, the tech is not independent of house money.

 

I know. I will probably end up having them install a used unit. I'd do it myself but I don't have separate equipment to avoid contamination and to measure that small of a charge.

 

I'd hesitate to let the dealer do any major overhaul for something which isn't covered by warranty. At least, not before I checked around to see what other options were available.

 

Yeah that's why I thought of using a used part and not letting them make money on a new one. But it's still x hours of labor no matter where you go, on recover and recharge AC

 

Trent,
Curious to hear about your AC usage that may or may not have impacted this premature wear. What do you usually set your AC at? Do you use it much when the car is not in motion? How many total miles do you have?

 

I normally have it set all the way down at LO and air on vent or vent&floor. I do use remote AC once in a while with the car plugged in. I pretty much live on AC in the summer. I have 46k miles.

 

Could be low on fluid. Power-steering pumps sound similar when they're low on oil.

Or perhaps over-filled.

 

Holy crap you like it cold, haha!

Even with this sort of heavy usage you would expect it to last longer than this though.

 

Another possibility is "floodback." Too much refrigerant leaking through the pump and into the crankcase.

 

why is it attached to the crankcase?

 

He means the crankcase of the AC pump, which a somewhat of a misnomer, because it doesn't use a crankshaft with connecting rods and pistons, but it's the housing around the scroll.

 

Can anyone confirm what the root cause of the noise is? I have a 2010 Gen 3 with <60k km that I bought used and it's making this noise now! My dealership says they won't inspect since it's not covered under warranty anymore... Is it a simple fix or does the compressor need to be replaced?

 

no, but i wouldn't worry about it as long as it's working.

 

The compressor needs to be replaced. A little research on home HVAC with scroll-type compressors shows that ANY noise is MOST OFTEN really bad, except for the normal electric motor hum.

If the compressor dies then it will most likely send metal into the condenser and perhaps other parts of the system. The condenser is a parallel flow type which can't be flushed out, so it will need to be replaced as well.
