A/C Compressor noise

Alright, so I'm trying very hard to make this 4 cyl. 2.4 liter engine, 1995 Mitsubishi Galant S, alot more comfortable than it was when I first got it 1 week ago. I just brought the car to the local mechanic who charged me $80 to put in what he called "like 3 lbs of ****![refridgerant]." Of course, when I was strolling through Target the next day I seen that 134 wasn't too expensive and I feel absolutely ripped off. That's another story though, right? Anyway, whenever I got the A/C blowing and I'm going say 30mph or faster and I apply then brakes, I hear sort of a grinding noise comming from the A/C. I guess it's the compressor. I hope that doesn't mean that there's a leak? What do you fellas think?

Bear in mind that 80 bucks included labor and diagnosis, so just by going on the cost of R134A, you're not being accurate. People have to make a living

With that being said, if the vehicle makes noise with the A/C on, make sure the belt is tight and in good shape. If not, bring it back to the shop and have them make good on their repair.

belt...?

Which belt? not the timing belt? Serpentine belt? I had no idea there was a belt involved with the A/C system. Thanks, I have them[mechanic] look at it! Hey, what does it take to become ASE certified? I'm tired of not knowing anything, if you know what I mean.

The A/C compressor has a drive belt. Sometimes one belt drives everything, other times it has separate belts.

The timing belt is internal and drives the crank and camshaft. No bearing on the A/C compressor. If the timing belt broke, the engine wouldn't run . The timing belt should be changed at regular intervals as suggested by the manufacturer.

As for ASE certification, go to the ASE's website. You have to pass a competency exam and be in the trade to get ASE certification.
