    You need to add it under a load slowly to see if it helps. Add a little under a load then let it run that way for a few minutes and see if temps fall. If not then the cap tube is too restrictive.

    Yeah it very well could be undercharged that's why I said start by adding some refrigerant and see if that helps since it's easy to do. Do that with full airflow though. If it doesn't help then you...

    First I would try adding some more refrigerant since that is easy to do, but my bet is on the cap tube being a bit too restrictive since the high side pressure is lower now that it is cooler and...

    Yeah that is working great, very nice! Oh and you're right, it should do even better when your ambient temps are cooler.

    Awesome, glad it helped! For fine tuning to get better temps it would be good to get some evap in and out temps with a load so we can see if your charge and cap tube is right. Seems pretty sweet so...

    Yes, you always want the liquid line exiting the condenser to be straight as possible. Liquid doesn't climb up very well, so you end up having to overcharge it to get enough liquid at your drier...

    If it were overcharged your compressor would be icing up and you would be getting liquid returning to the compressor. You can try removing a little gas to fine tune the charge under a load since cap...

    Yeah that static pressure is fine. R-404a is a fairly high pressure gas so it's normal to have a higher static pressure than something like R22 or R290 for example. If you were using something like...

    I'm assuming this is still using R-404a? If so then all you do is use the P/T chart for R-404a to determine static pressure at a given temperature. For r-404a a static pressure of 175psi indicates...

    From the pictures it looked like every other 180 elbow went up slightly. I have a heat exchanger that does that. I think the pictures were just misleading, I was assuming it was the same as one I...

    The heat exchanger you are using isn't a condenser but an evaporator. Follow the flow through the 180 bends and you will see it doesn't flow down consistently as it should. It goes down then back up...
