I wasn't done yet, but hit the wrong button.
Here's the link featuring BERT.
Anyway. Scaling back from the hugely educational stuff, another YouTube guy I follow is Dave – the one man operation calling his company Nor-Cal Refrigeration & H.V.A.C. He's located in…uh…Northern California.
I like Dave's videos mostly because of the entertainment value. He has a wonderfully lighthearted spirit as he addressed some of the grungiest refrigeration jobs while we simply ride on the top of his head (or in his van) knocking out the jobs.
His videos are real wold stuff. They're not classroom. His vids are much shorter than Chris', but are ones where I'm always wanting to tell him “Been there and done that”. No, not there in Cali, but I've been in the middle of some of those situations. Under the blazing hot sun of summer or (he doesn't much experience) iced over rooftops of winter.
YES. Refrigeration systems fail in the winter too. They don't perform well in the winter if a headmaster or fan cycle control gives out.
I also like the bike rides he shares. He's a music buff too (which he shares occasionally) and a scuba diver (which I've been…and he also shares).
I find Dave's videos the most entertaining if I want to watch videos of the WORK I've already done…or could be if I was still doing refrigeration.
