A/C Sign In

I took my car to have my A/C checked and I told them we attmpted to put A/C pro in but it's still blowing hot air, I informed them that the compressor was working fine engaging and everything but the pressure gage was reading in the red, let him know I think we may have a leak or put too much A/c pro in because it's still blowing hot air but everything is still coming on just blowing hot air, they checked it he came back said it had a leak they can vacuum everything out put dye in and find and seal the leak only going to cost me $156 including freon and everything only going to take them a few minutes. I was like great. They came back after attempting to do this told me I had a bad compressor and it won't engage it will cost me $959 to fix it. I said the compressor was working fine, I thought you said it was only a leak after your inspection. Not clear how I could have a leak one minute and need a new compressor the next. I think they broke my compressor. What is your professional opinion? Not sure why they didn't tell me it was my compressor in the beginning when they first checked it and I'm no mechanic but isn't that one of the things you check first when trying to diagnose the problem.

Re: A/C Sign In

I think the odds are better that YOU broke it when you just randomly started pumping junk into the system.

Then cannot accurately analyze the system until the system has been evacuated and recharged with the exact, weighed amount of refrigerant so it is not surprising that they didn't know the compressor was bad until they recharged the system.

Also, you should immediately change your user name before the spammers get you e-mail address.


We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

Without being able to see the truck makes it harder...

Sometimes it's better to talk to the tech and not the SA...

You had a cooling problem before you went in....The 1st thing they probably did was to pull the old refrigerant out, put a quick vacuum on it and then charge it with the correct amount.. Then check the pressure readings and see what they have.....

With a correct charge, if the pressures were equal while the comp is running.....That would indicate a bad compressor....

It could be something as simple as the SA using the wrong terminology when he was telling you the problem...

There really isn't anything they could've done (normally) that would damaged the clutch or kill power to it....

Have you looked under the hood to see if the clutch really isn't engaging now when you turn the a/c on?

You know I am so glad the parts stores and wally world sell those DIY suicide cans. When the customer blows up a system, that is just more money for us techs.

Always charge the system with the correct equipment in the manner Sid stated. You do not top of automotive ac systems. It may work fine on your home ac system, but not automotive. Make sure they find the cause of the compressor failure. Most of the time it is from a low charge or inop cooling fan that takes them out prematurely. 130K on an original compressor wasn't a bad service life.

Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.
