    YES....good plan of attack.

    80 series AC intel?

    Please take it to a shop and have them do ALL the work you need to have done. You don't need to understand it, you just need cold air. You can not 'drain' refrigerant, it must be 'evacuated' (captured using specialized machinery). The DIYer (without equipment) can only let refrigerant (in its...

    ^^^^ Actually there are 5. There is what my Wife says 'Matters'. Somehow.....we always have to go with that. :frown:

    80 series AC intel?

    Correct. Static pressures have a use. Contamination is one (though you'd have no idea how bad). Static pressure will also reveal if there is enough liquid refrigerant in the system to satisfy the minimum pressure required by the binary switch to allow the compressor to engage. But again...not...

    A few corrections for sake of accuracy. Not mean't to condemn, just need everyone to be on the same page.

    ^^^^^ I would like for you to take a sheet of paper and place it over the lower half of the diagram and NOTES written there....and never look at it again. As most of it is wrong. In fact, anyone reading this.....please disregard the notes. I am going to explain in a simple way how A/C...

    Nope. And that is part of the problem when a system has been 'serviced' several times but a complete evacuation and flushing has not been done. It is common place for techs/DIYers to add refrigerant that has a couple of ounces of oil in it when they top off a unit or replace a single part...

    80 series AC intel?

    No...the sticker gives a range for the physical weight of refrigerant to be used. As weighed on a scale. IF you remove and replace an item (compressor, drier, condenser, evaporator) each of these parts require a specified amount of oil. You can add it directly into the part before installation...

    ^^^^ This is almost certainly what happened (no evacuation or poor evacuation). Drier desiccant is saturated and at some point will break down and travel to his new TXV where it will clog the screen. I have no doubt there is both air and moisture in the system. OP has a 'roll the dice'...
