I refuse to let my guys put clutches on.  Too many come backs.

Things must have changed over the years. I did clutches and bearings a lot back in the 70's; fairly simple then with the right tools and axial compressors

Sometimes the compressors were actually locking up causing the clutches to burn up.  You wouldn't know till you had it back together and running as they felt and sounded fine when cold and not under pressure.   After I ate about 3 clutch jobs I put an end to it.   I don't know of any shops around here that mess with them.

meaning price for compressor not lower price for just the failed parts. You need better mechs!

 

The clutch was usually around half the price of the reman compressor.   Labor was slightly higher to do the clutch so it wasn't a big difference pricecwise.

Just did a search. You are right clutch and bearing is 1/2 of compressor. Now how much is the charge to evac and service Freon when you don't have to with a clutch change? More than the compressor cost in my experience.
What was the malfunction? Did clutch engage statically or was the clutch disc broken (more time than not) If so, were you able to turn compressor by hand? If clutch engaged but was obviously slipping due to compressor lock then compressor. Simple troubleshooting that sometimes screws us.

Deleted everything I had written. Anyway going to try to save $1100 cause I'm cheap...

 

 

 

 

I missed your original, now deleted, comments, but the two subsequent posts to Volvo videos make me curious.   Volvo and "cheap" do not go together, neither do Volvo and inexpensive.  EVERYTHING on my brother's  Volvo was expensive to repair, even if DIY.  After too many repairs, some multiple times, he got rid of it, to be replaced by Camrys and Subarus. 

 

The only Volvo he ever liked was the stern drive in a boat. 

 

Good of luck with your A/C repair.  I'd like to know how it turns out.

A/C diagnosis can be tricky, even for experts.  I had a new '91 Taurus that had faulty A/C.  After 5 failed attempts to repair it, Ford bought it back under the Michigan "Lemon Law."  It was replaced in '93 for a net cost to me of $600; not bad for two years of use.  The $600 was to pay for two upgrades; 3.8L and passenger air bag.  

 

It was comical toward the end.  On the fourth and fifth attempts a Ford factory specialist was involved.  He got in the car and put, what looked like a meat thermometer, in the A/C vent to see if it blew sufficiently cold air.  I chuckled, "You won't need that.  When it quits it feels like Saigon in August in here."  The clutch and compressor were not the explanation.  If Ford could have figured it out, they would have fixed it.

 

The other lesson learned was to hire a lemon lawyer.  Ford was jacking me around on replacing the car.  Ford expected me to pay ~$2,000 toward a replacement. After several fruitless dealings with Ford reps, I called an attorney who specializes in lemon law cases.  She sent a single letter to Ford and the deal was done.  Under the law, Ford replaced the car and paid her fee.  She knew who to contact at Ford. Ford knew they couldn't win. The BS stopped immediately.

Some clutches can't be replaced on the vehicle.  Heck some compressors you can barely get to now to remove.  Do you work on a lot of front wheel drive cars?  Actually you probably will be soon.;)
