    I would check the price on R 407a.  I found it was cheaper and the blend is only 10 percent more r125 and 10 percent less r32, and the same amount of r134a.

    hey jim, do you ever have issues with your cps scale? i have the scale as well as my other employee and we both get random "adp on" on the startup screen- weird. once you recycle the start up a couple times it works correctly. they are new scales as well and cps does not have an answer either go figure.

    Since I started watching your videos a few weeks ago, I have a new appreciation (and interest) in these coolers when I walk in them to get a case of beer.

    Thanks again for sharing, Jim.

    How come my R22 Walk In Cooler work fine in winter, but whenever it Is summer my cooler's refrigerator compressor, doesn't keep the right temperature and not running properly. I need to turn the power of it on and off in order for it to work. Everyday I have to switch the power on and off once or twice a day, whenever it I the hot part of the day.
