HVAC - Isolate to Diagnose

[@Jc124]

The information you give is so great,started doing HVAC a year ago with no experience and I’ve watched your videos almost everyday while working in the field and I’ve learned a lot,Thanks man!

[@monteglover4133]

I’m a 45+ year tech and find your videos interesting sometimes reminding of things and the occasional well da Ghost voltages in many cases will drive ya crazy in systems with massive electronic controls Thank You

Essentially, an electrician back in the day was a guy that volunteered to get shocked. My actual nightmare. Lol, love the content.

Indoor fan running: 1)power ✅ 2) control power ✅ 3) check safeties 👍🏽

10:45 Reminds me of something my dad said when I was about 14 years old. I was tagging along on an AC service call and I pointed at the capacitor and asked "What's that?" He said, "That's the capacitor, don't worry about those, they never go bad." At that time, that was a true statement! That was when the compressor and fan motor each had a separate capacitor and the compressor capacitor was about a foot tall and weighed 5 pounds!

[@austrianpainterinhiding88]

That is funny. Nowadays even the biggest brands are putting cheap, Chinese caps on their equipment, it seems like we replace them once a year. And with everybody going away from the PSC blower motors for the modules it's even more of a pain.

[@chrisdeanndavison3626]

@@austrianpainterinhiding88 I've been using the Titan HD USA-made capacitors exclusively for about 4 years now. Unfortunately, I haven't seen a drastic decline in capacitor failures with them either. I've had quite a few of the ECM modules fail too. Manufacturers tend to blame power surges, but I'm not convinced.

They where all thrown out with kitchen scraps in the landfill to rust leak p.c.p. out into the dirt , should have saved them a lot of old caps had red dot for line incoming shorts to case not load start winding connection.

We were just taking about this at work with the new guys yesterday. Gonna show this to them.

Always makes my day watching these vids. Thank you for your time and knowledge. 🇺🇸

This man is a HVAC god

[@thomasquijano9519]

Excellent video. My dad used to test electrical with his hands.

[@jkbrown5496]

I believe I found this at Heating Help: “The two best tools a troubleshooter can have are a bright flashlight and an open mind.”

[@mackenziegray2090]

The megohm tools is not used to diagnose a bas compressor. It is used to measure Insulation resistance. If you read "bad" on a megohm then you want to talk to the customer that their compressor is close to being on its way out. As in they should start saving for a new unit or compressor.

Thank you for an excellent presentation on the practical aspects of troubleshooting. Between your videos and "Pine Hollow Auto Diagnostics" automotive troubleshooting videos, you really provide an excellent overview on troubleshooting along with real life experiences in the field. I find all your videos very informative - Thanks (from an Aerospace Engineer who troubleshoots spacecraft both prior to launch and on-orbit).

[@brianlittle717]

Great video. For low voltage shorts I’ll put an ammeter on the secondary and sometimes I’ll jump across the fuse but it’s not always necessary. I’ll have all my wires disconnected and just momentarily, I’ll touch one wire at a time to hot. I’m just looking to see if it sparks or not. If there’s a short to ground, there’s gonna be a spark. The transformers will last a few seconds under a very high load so they won’t burn up in just the time it takes to momentarily touch the wires. Doing this, you won’t waste a single fuse.

[@stevem9629]

Thank you Bryan for posting this video, it was excellent!

[@brianmcdermott1718]

Grear video Bryan. Thank you.

[@michaelcostello6991]

Good guidance, Thanks

[@paulgaras2606]

If you want to work on VRF equipment, You need this mentality.

[@ericsamur4341]

Wow bro your so smart with this stuff appreciate all the info you give every vid!

[@r1cky42]

Great video toms of info

[@Joe-Bourbon]

I like learning about HVAC when I watch a comedy special.

[@richarddomasig514]

Thanks..very useful information.

[@soloch69]

Love it keep them coming now I need a Beer 🍺

[@nilborne1]

ghost voltage...makes me crazy. Like your contactor tip.

[@harrygilbert4593]

It’s tuff when 4 18/3 wires are ran in a commercial building for a heat pump and both Technicians are new to the “Service “ part of the Trade

[@luke9129]

Take them socks off, poor smuck, haha, but seriously great information Bryan Orr.

[@jorgeparedes4660]

Thank you so much!!! I like it Nice video I was hypnotized watching the video 👌 😂

[@HVACOvertime]

love it

[@thatonedude6695]

Sounds like "hop scotching" that I was taught.

[@maxgrind438]

What is a time delay?

[@realestateservicessaleshea99]

Thanks again for the videos! 🍺🍺🍺🥃🥃⛳🎳

[@brushben22]

Why was that free app that Brian came up with again?

[@caru3257]

I met a young guy who asked me to teach him the tricks of the trade. I told him there were no tricks.

[@kareemnorton7696]

Hey 👋 how about moving to Barbados😌 so I could be an apprentice under you.

[@stephwaylonwells3218]

👍

[@aaronbrown3573]

That's coors not miller.

How can I get one of those beer can cool t-shirts

[@timrob0420]

Dude I want a beer can cold shirt please
