Your content deserves way more views. Great job. I come from a residential hvac maintenance and install background (mostly grunt work on installs) and I recently got a job with a commercial refrigeration company. Trying to stay on top of it.
Very informative for the Text that are starting out you start out right you'll have no problem and diagnosing the refrigerator or freezer. Retired refrigeration and air conditioning mechanic. Over 50 years.
Its great that you are teaching the need to know coil temps and the need to match the saturation temps to whatever refrigerant is in a particular system, the PT chart instead of just relying on a smart manifold or probe reading alone.
Yes, that is for reach in freezers. Should be 1 closer to 1 degree per minute if the system is working correctly. The lower we get in temperature, the closer it will get to 1 degree per 2 minutes.
I’m still wondering how do u determine the evaporator TD to be 20, I know pre 2006 most units condenser td is 30 Where can I find this info I feel it’s a good thing to know seeing how it’s working for you
I'm very interested in your reasoning for which applications get desired temp - 20° or desired temp - 15°. Also, which applications get 0 box temp compared to -10°.
Depending where it is it will exhibit the same symptoms, low suction, low head, could be partially restricted capillary or Txv screen, or filter drier partially clogged.
Great vids btw, I’ve watched many of your vids, you do good work, no way would I want to or have the patience to document service on the job as you do, much too frustrating, great job.
They are training videos for all the techs I work with, has really helped with the learning curve. If others can find some use out of them, even better.
Those trough heaters are a joke. The silver tape holding them almost always fails. For what these units cost mfg a track for the heater. What do I know just a dumb service tech.
