To dianemarie909, there are actually quite a bit of different methods and varied schools of thought as to what is the most accurate method. I like to add the gas little by little through the low side or suction side and monitor temperatures and pressures. Some people weigh in refrigerant by calculating manufacturer specs. and adjusting for length of plumbing with the compressor off through just the high side as a liquid and some through both sides.

Another great vid ! Thanks again!

@mrsokla I only learned about the electrode diffusers in trade school last month. I didn't know that keeping them cool makes such a big difference in the service life of this type of equipment. I know that suction line superheat is used for determining heat transfer on the evap and subcooling for the condenser, but that tells nothing about those electrode diffusers. And what the hell is discharge superheat all about?

Thanks johnnyrotten52, I show how to secure capacitors in my "Air Conditioner Not Cooling" troubleshooting video.

Good straightforward charging. Hope you secured that dangling capacitor.

What about superheat?

@eagletek1 Oh Yeahhh, SuperHeat and SubCool the finer things I would like to get into more. More accurate measurements are needed when working with more complex and sensitive equipment and systems. Capillary tube and fixed orifice systems allow for some variance but other advanced systems require more precise charging.

I like to poor a couple cups of water on the compressor when its running too. This helps to cool down the bearings and greatly increases the life of the electrode diffusers inside the valves. allows them to get nice and cool and oils them up. Great Job Jedi. Best Damn video i've seen in a while.

Glad you enjoyed it mrsokla. Thank you (o:` much!

Informative, but at 48 sec in the video it says the blue gauge is for liquid! I don't see a lot of our maintenance guys purging their lines and is probably the reason we do so many compressor changes and due to overcharging because they only know the "beer can method."

@rsgarnerthree Yikes you are so right. My bad, my bad, my bad. I have done what I could to fix it. Whoops 0:48. The high side is the liquid line and the low side the vapor.
