How do you leak test during an install/repair? The guys I work with call it good if they pull a vacuum down past 500. I just had this fail for me so now I've been valving off the pump and making sure...

Yeah, I'm going to try this when the time is right. I've seen demonstrations of brazing w/ and w/o nitrogen and the results are honestly amazing. Maybe I 'll demonstrate this to them also and give...

Yes, they use digital multi-meters. I don't know anyone that still uses a voltmeter and an ammeter and an ohmmeter, etc. It's just outdated, I know. Look, my point was just to imply that analog...

I most definitely am being influenced by the "old timers" that I work with because I spend 40+ hours a week w/ them. And No, I have NEVER seen any proof that the Testo 510 is off in any way. The...

Haven't been in the field for very long (I admit), but I already realize the EXTREME communication gap between engineers and those of us who work in the field. On another note it seems that Lennox...

I asked this question awhile back and got heavily referred to the Testo 510. So I bought it and I like it for the small and simple to use aspect of it. Then my company ordered me the Dwyer U-tube...

My company uses micron guages. However, we do not purge with nitrogen. I'm 9 months out of trade school and was taught to purge with nitrogen, but my company does not practice this, so now I don't...

I've got 2 of these so I can test hi & lo fire w/o waiting 10 min. (or whatever the delay may be), on gas furnaces. Have ran into trouble with some screws actually having been de-magnetized, so...

I have the Milwuakee M12 impact & love it. I saw a youtube video where a guy did a pretty good comparison between the M12 and Bosch's impact http://www.youtube.com/watch?v=dx6ttcAFVM4. Hope I helped.

Some areas (including mine) require purple primer per code. I agree w/ the visual aspect, but gotta follow the rules no matter how ridiculous.

I'm in Iowa (small rural community). Completed a trade school in May & started out @ $12/hr. Busted my ass and in July was @ $13/hr. Then, took an apprecticeship placement exam and got put in the 3rd...

Just ordered the Testo 510 manometer. What static pressure tips do you have/suggest? Also, what lengths are they?

I got out of trade school back in May and have been working for an HVAC/R, electrical, plumbing contractor ever since. I would say 1) Understand the basic mechanical refrigeration system and it's...

I was told to spray water with a simple garden sprayer up the fire-box, with the blower pulled, and then look into the heat exchanger for signs of water running down in it. I've praciticed this...

What tool do you use to test SP? I've yet to buy a tool for this (I'm an apprentice) and my co-workers all have a Dwyer oil manometer that can be mounted horizontal for SP readings. They laughed @ me...

Thanks to those who replied. ACCA Manuals D & T are now on my priority "get list".

1st time post, long time browser. I am an apprentice for a company that does it all (hvac, refrigeration, electrical, appliances, plumbing, geo-thermal) and have been looking for a place in the...
