      hi lech, I watched some of your videos and it seems you know AC systems. I'm in Portland, OR. do you know anyone smart, and reasonably priced to recharge or diagnosis AC systems issues in the Pacific Northwest?

      2013 Prius, I have code b1498 and believe my compressor is bad, all ac fuses check good. Fluid is seen in the sight glass but no bubbles are seen. When doing the auto and recirc I get 00. What equipment is needed to recharge r134a and oil, ex vacuum pump, recovery machine or both. I prefer to tackle most task as long, as cost makes sense.

        You may be able to sheet a shop to recover refrigerant for free.

        Gauges, vacuum pump, scale accurate 5g preferable. Or close.

        May need condenser if burnt compressor with metal flakes or burnt oil.

      what's the minimum vacuum pump type I should used that will get me through a few months?

      On a used pump for my new auto service I'm not worried about the seal like with any eiother gear. I'm worried about getting into the minimum micron levels for the cheap. How farf off is le Harbor Freight 3 CFM?

        How small or how big the CFM is not important.

        The CFM is how fast you get there

        What’s important is the micron rating of the pump?.

        Do you want to get a two stage vacuum pump NOT SINGLE STAGE

        The lower the micron rating, the better

        If you have a micron gauge, you can always test the pump.

        Good vacuum pumps will be somewhere around the 15 µm to 20 µm range

      I need to remove the wiring from gen 2 AC compressor. I currently don't have a tool that will remove the special bolts for the wiring.

      Can you tell me what tool is needed?
      1. lech auto air conditionin
        lech auto air conditionin
        I have never had the need to remove the wiring out of the compressor.

        But if I could remember from 10 or 15 years ago I think I tore one down because it was a burned out compressor and I just wanted to look in it and I hammered on a different socket that almost fit a little tight and forced it off through friction fit.

      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.

        If the inside of your system is completely totally black on every line connection replaced condenser replace expansion valve a old 2009 evaporator replace that too don’t reuse it at that age flush all your lines replace I need that have mufflers

        Alright, everything is back together. I wound up replacing the Compressor, the rubber AC lines and the condenser. The radiator was PACKED with sand so I replaced that too. All Denso parts. Car runs great, no leaks, coolant is burped. Next I'll bring it to my local Toyota Hybrid AC guys (yes I found factory trained guys) to recharge the system correctly. wish me luck!

        Yes the brand new condenser comes with a desiccant bag installed inside of it

        Well my Hybrid AC guys here in Boise said the system is working well! I feel rather smug.

      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?

        Oil balance remove both quads turn compressor upside down for 10 or 15 minutes constantly moving it a little to the left middle right shifting it forwards and backwards to drain out oil and then replace For instructions the amount that came out of the old compressor

        I don’t have no videos on disassembling of the front for a condenser or desiccant bag some people just loosen it up Lyft and tilted forward removing the bottom cap to replace the bag

        The aboe link describes my issue. I think it is some type of relay or something. Also I live in Fla so defrost is only related to humid air, not ice an cold. But the Defrost is an issue but the AC issue I think if I get fixed then defrost will work

      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.
