lech auto air conditionin

my ac compressor as not been working well for sometime now. On Sunday it stopped chilling finally. Today I check the low pressure line and saw that he refrigerant was black. Pls what could be the cause of this? I am going to buy another compressor tomorrow as I can't drive without ac in this hot weather.
What else do I need to check before I fix my new compressor? Hoping for response.

Yes I met plugs

Hey there. So I’m about to embark on replacing my compressor and condenser and the rubber hoses on my gen3. I was strongly recommended to hit you up for advice. Got a minute or two?

Hey Lech do you have time for a question on 2012 Prius AC issue?

A little about myself. At 15 my father introduce me to air condidtining and electrical trouble shooting. My first hands on job for that summer was rebuilding General Motors A6 air conditioning compressors by frigidaire . At that age my father thought me not to just replace parts, but what caused them to fail in the first place. Not just replace part like a monkey . find a better part procedure or material so will not happen again or last longer. A/C compressor should last the life of the car, unless of neglect or poor service procedures . that's why today I am still servicing vehicles with compresses that are 50 +years old.
For the last 17 years in my own business as Lech auto air conditioning. Iv been a mobile vendor providing in house a/c service for auto repair shops and body shops. Trying to stop shop from taking shot cuts that spell disaster for a a/c compresor.

Most service shop learn A/C in a book or sitting in a few hour or 1 day class is just enough to cause damage, just enough to get the car out the door and collect money$$$. Many learn on your car at the customers expense. Some love to fix cars, some just like to make money$$ the later ARE THE ONES TO STAY AWAY FROM!. They only want to learn the least for the least amount of time and money to make the most profit ( sounds good for business ) there are not short cuts fixing or servicing A/C. A A/C compressor should last the life of the car? yes but so few know this. As long as a out side force dose nothing to damage the system or rubber seals fail, it keep going and going!!!. There are just some people who can not comprehend what they cant see, touch, smell, hear. Unless you have 110% understanding of the physics, chemical, thermodynamics, ect, the more wrong parts that will be replaced and the less rights part that have not gotten replace. It works for now but them fails.

air conditioning problems, have you have your prius a/c serviced at a shop or after having you prius fixed in a body shop had your compressor fail,
i only work on air conditioning in san francisco bay area. the last few years iv seen way to many prius with burnt compressors after leaving body shops after repairs. most cause have been , over charged, under charge, no oil, too much oil, wrong oil, air in the system, moisture in the system and poor quality after market condenser.
Prius has a good a/c system, but its the repair shops doing the service burning up the compressors and the customers are paying the bill for their lack of knowledge about the new electric compressors.
