    How about a video on determining the charge of a mini split with one service valve and R410A. It is good to refresh on the procedures now and again. Things change fast in the mini field. What was good a couple of years ago could be obsolete now. Might even be some short cuts I am not aware of. It would be of great value if you do it during the heating season. I have viewed several videos which want you to shut off the inside exchanger and run the compressor alone. Most of the modern mini splits I have dealt with have the inside unit powered through the compressor and no positive disconnect. I am not sure that the design allows the compressor to run when the inside unit is shut down with no damage either. Thanks for the video.

    This tip really helped me figure out how to squeak a pound of gas into my leaky Fujitsu, which I don’t feel like fixing just yet lol , thanks for the tip , it worked great , and I’m really appreciative of the sman 480 I got myself for Christmas!!! What a valuable tool!!!!

    Can you please show the proper way to flush line set from r22 to 410a on a condo. We can't not replace the line set. but we need to flush it. Thanks

    How do you check the super heat or sub cooling using this method? How can you be sure you are not overcharging the system? Thanks

      This way of charging your system is for when you have calculated the charge of the system prior to charging. No need to check super heat or sub cool when the system is not running and you are weighing in your charge. You are free to check super heat and sub cool after the charge is in the system and after at least 10 minutes of run time.

      @@daviddarling2970 I missed you mentioning this is a method to weigh in a charge when it is cold. lol

    Another great way is to just have your system in a perfect vacuum first isolated from the condensing unit and then just doing your calculation by length equals weight

    This is good idea but which water do you using?

    By your video you’re charging with gas? Not the way 410 is charged.

    • @k.sullivan6303
      @k.sullivan6303 2 года назад +3

      Thats what I wondered. You have to charge with liquid or the refrigerants in R410a separate.

    Does this mean it’s 93 degrees in that room?

    120 Fahrenheit or Celsius

    Hot water?

    • @lizaguirre11982
      @lizaguirre11982 3 года назад +1

      Yes, domestic about 120 fahrenheit or 48 degree celsius

    • @johnstonesupplybalsangroup1982
      @johnstonesupplybalsangroup1982  2 года назад

      Yes it is domestic hot water, which is usually around 120 degrees. You want the water around there (no higher than 140 degrees) so that it doesn't heat up your refrigerant too much!

    What? You're telling me when you increase temperature you increase pressure? Dang you must have went to the same kindergarten class I went to!

    Did this in the middle of a snow storm while charging a heat pump. It’s not fun.

  • @Mike-cc3bc

    -410A refrigerant must be removed from the drum in a liquid state. The two refrigerants that comprise it boil at close to the same temperature. Therefore, for slight leaks, R-410A can be topped off. Just make sure it's removed from the drum while it is in a liquid state.Apr 5, 2004.
    Another video with misinformation. Do not fill r410a in gas state....

    This is great, only thing that sucks is when the CFM is blowing on your face and the water cools wayy to quick due to it being -3F - 40F in Texas 😅😅

    Use a home heating pad. That’s silly

      Better idea but this works in a pinch.
