Here I am trying to diagnose this no heat furnace and supervisor strolls in puts himself right between the furnace and me as I’m sitting there. Ge was acting like he owned the place. He kept rambling something about treats and pets but I had a full schedule. We met in the middle with some pets and a blower/module replacement quote👍😂

Front and back washed with coil cleaner. Have been using just water for 45 mins.

I like carrying a flat side flashlight with a magnetic base for working on furnaces. I keep one in my shirt pocket. I've gone through quite a few, but this one has been the best by far. I'm not a damned salesman, btw. I am a flashlight guy though and wanted to share this one with you guys. (~$25-$30 on Amazon).

To top this call off, I even found a 2 inch section of copper tubing in the attic under the insulation 😎

If you actually enjoy learning, and real troubleshooting. Make the jump to commercial and or industrial work.

I was 21 years old starting out in resi. Did maybe two years and hated the work. Was going to just quit the trade and find something new.

If you’re in a similar spot that I was in, before you quit, explore the other avenues.

If you want OT and big paycheques, go for refrigeration. If you like a regular hours, plenty of commercial HVAC places offer that.

First time hitting freezing temps here in CT. Many calls. Go to the first one for upstairs no heat. Hydro heat. (Boiler with a heat coil in the attic air handler)

No voltage to the zone valve at the boiler. TO THE ATTIC!!! Zone panel showing no call for heat, of course the customer shut off the tstats….. why are people so dumb? How are you gonna have me try and find a no heat issue when the system isn’t even being told to make heat. Ugh.

Long story short. Installers installed a new AC and of course messed up the wiring on the heat side.

Can I run my evap pipe behind this, it'll be suspended in the middle of the wall with a clamp so it isn't just laying on the strut, boss is getting me to pro press it so I don't have to worry about brazing, I think it would look best but just worried about the legality

Hey I’m here asking the union guys, realistically how often would a guy expect layoffs if I joined a pipefitters union? I’m considering joining my local but I’m wondering about how frequent layoffs happen and how to avoid being stuck on unemployment for months as a new guy.

I know the money and benefits are good in the union but I don’t wanna leave a guaranteed job with guaranteed work and end up with constant/repeated layoffs.

Brought power draw from 1200 watts to 450 with the heat exchanger added

Apparently someone is trying to train AI robots to learn complex jobs. Thoughts?

Got a new clamp meter and I see how much size actually matters.

How dare I forget to use a highlight and make a joke about it.

The company I work for partnered with rocket groups and these scummy sales men want paper estimates with everything highlighted. I am against the over pushing of sale they want but I am forced to follow their rules and I forgot to use the highlighter on an estimate I had to do.

Anyone read about the danfoss attack in the EU? Thats some crazy stuff. Could you imagine being the on call guy and having to deal with that? Supposedly they cranked the Temps up to 130* a lot of the places I work have zero backup. Its crazy to think a single hvac controller would be hacked so easily 😆

Was sent to a univent today basically a fan powered heating coil wall mount, maintenance man claimed blower motor was hot and shutoff wanted it replaced, customer supplied parts. Motors wiring diagram confused me so I just ohmed the connections found primary winding and put cap wire on the other lug it ran backwards so I swapped the primaries around. 120v 1/4hp 1ph got it running but I want to understand what the schematic was saying

tldr : whats with these schematics and how to know how to wire it correctly old one was mcquay

How often do you all check your gear? Nothing is worse than being out in the field and waisting time searching for issues that a bad hose o ring or bad micron gauge has caused.
Any tips or tricks you all use to make sure your equipment is in top working order?

I guess at least it's symmetrical:

VRF leak checks made easy.
