    Very informative and to the point video! I wish i had RUclips when i started in the trade, went to school at night worked during the day, no body wanted to explain anything and went as far as saying they weren't there to teach anyone. Thanks for making the videos i know a lot of people will benefit from them and God wii reward you

      Main advice I can give you is to not let the system win. Take every call like a challenge and if you can't figure it out you lost that one. Sometimes calling for help is necessary but before calling do everything you can to avoid calling someone. It will help you on the next call. Thanks for watching:)

    Trying to become a new technician and do ac maintenance calls. I also am a lead installer. However I’m still learning I got thrown out into the wolves..I enjoyed this video. It made me understand to check continuity and volts from each point to see if there is a dead spot.. please make more for beginners thanks. Helped a lot

  • @jeanluc397
    @jeanluc397 23 дня назад

    you ever use a fieldpiece SNCV1 24v ncv tester (or comparable) tester to do it quicker without having to poke leads down in the wire nut not knowing if your in it or not ? just a thought you might have to pull other wires out of way a bit with your fingers so it don't pick up them. maybe I'll try your hopscotch method with ncv and poking and see what happens

    • @SurfBrosHVAC
      @SurfBrosHVAC  23 дня назад

      The fieldpiece multimeter I have does have an NCV mode which I have used on occasion but I prefer to see the voltage with my own eyes

      Future video my friend. Shorts are a whole different thing and in my opinion are must easier to get the hang of than troubleshooting in general. Really not all that hard to figure out. You can call me on the number in our bio if you need help figuring out a short

    So if I verify power going to the board and no power coming out should be verifiable the board is bad right?

    • @SurfBrosHVAC
      @SurfBrosHVAC  5 месяцев назад

      I would say yes in most cases. Assuming you've checked the fuse. If you have 24v in and nothing between the R and C terminals for the thermostat connections that is typically a bad board or bad fuse.

  • @theprofessor5584
    @theprofessor5584 7 месяцев назад

    Really like the video, but can you do a white board explanation with a few lines just showing what you mean by certain things. Because we couldnt see what you were testing so very difficult to visualize. Example, the relay not allowing power to the transformer, or where did you find the common? To then use the other lead to check for low voltage? What points are you looking to find 24 volts in the low voltage system with one lead on common? Your great, but if you are looking to help make other techs better, some white board breakdowns would help us better understand what you are relaying.

      @@SurfBrosHVAC Oh, I get it! But since you have that fancy white board... "story board" you A-B-C-D etc path, what visual tells the story you're narrating? Close shot? Wide shot? POV? It doesn't have to be perfect, it just can't be confusing. It's okay to pre-script the important parts, you're trying to do a lot all at once - working on a system, teaching trouble shooting, and making a video. As you develop a work flow it will get easier but start your shoots with an outline/punch list and a couple paragraphs of specific language to make the video part easier.
