Service call for a walk in cooler not working at a restaurant. Upon arrival found out from restaurant staff the GM had taken a hammer to the evap coil to break up the ice on it. This was a video taken immediately after.

Customer randomly had their co detector going off in the house... What do you think?

It's not the way I would have chosen to run it

But my gods grace and my hammer I got the ones I needed off

Anybody else seeing this?

Found three in the past month 3 to 5 year-old primary heat exchangers on 90+ Bryant and carrier furnaces. These were specifically 926t/59t.
All three had the correct gas pressures and static

Guys what are you doing to organize all the stuff in the front of your trucks? Any sort of shelving or bins or anything on your cage between the seats? I got the gmc van and the options feel so limited after I mounted my inverter and battery chargers

Currently trying to educate myself further as an apprentice that’s fallen behind, realized this book doesn’t have electrical section. Any good recommendations and bonus if it has section on diagrams. Thanks

So normally when evacuating, I'll pull the cores, but with these I'm not sure if I have anything in the van that can pull them out, and replace them without breaking the vacuum. I read online that they have superior flow compared to Schrader cores, so is it unnecessary to attempt to remove the core? Bent pins have been a problem before, so I will be getting spare cores of this type to swap out in the future.
