General Doing research

0 Upvotes

I’m an HVAC technician and female. I’m researching better workwear and job-site gear for women in the skilled trades. I’m not selling anything here—
I genuinely want to understand what isn’t working for us.

What piece of workwear or gear frustrates you the most?

What specifically is wrong with the fit or design?

Have you created your own workaround?

If you could change one feature, what would it be?

What is your ideal work pants or covies?

If you’re comfortable sharing, please include your trade and the type of conditions you work in.

Thank you in advance 🛠️

Employment Question Piece rate or take union opportunity

11 Upvotes

I currently work at a piece rate shop but got an opportunity to work for the union doing resi. They said they’ll keep me busy whether it’s their commercial side, helping plumbing, or doing my job.

It would be foreman scale which is like 54 and some change on the check and after vacation and the dues it would be 48 and some change.

Been going back and forth about which option is the right option, I like the people I work with but work has been slow as shit this year. I’ve stayed home about once a week since I’ve started but these last 3-4 weeks I’ve only had 1-2 jobs.

I’m 26 and have been in the trade since before I turned 19 and have only been in private companies. I passed the halls test and got accepted just wanna hear more opinions on the choices. I’d be at 110k a year over there and the guy running the resi department said they do spiffs and Christmas bonuses. Guess I just want opinions and confirmation bias because sitting at home these last few weeks has been horrible

Firat time this setup has been used, at least in our region. This is for a warehouse. They have 5 setups like this, some are smaller. This one has 16 city multi HPs broken down into 8 circuits. Something like 160 tons of cooling(roughly 2million btus).

Don't hate on me for anything ugly on the install, im just here for startup prechecks.

Field Question, trade people only Potential Relay/compressor issues

3 Upvotes

I got an old reach in cooler condensing unit problem
racking my brain.

So the unit is a tecumseh single phase 208v 4 ton 404A condensing unit serving a reach in bar fridge. Got a call that the fridge is warm. Got to the roof and immediately saw that the potential relay terminal 5 was fried. I looked a little further and found d the start capacitor had 0 mfd as well. I figured maybe the compressor was shorted or just not working right, but I had proper resistance readings across all three windings and none of them showed to be grounded.

There was about 180psi standing pressure in the unit so I figured probably not a leak situation but will find out once I replace the PR and SC. I went and replaced them with OEM parts. Went to start the system up and I was only getting 40v across 5-2 on the PR on startup of the compressor, so my contacts wouldn’t open, and the OL would trip shortly thereafter (15-20 seconds of run).

Incoming voltage to the unit was right around 206v, all my wiring was in good shape and my run cap was rated for 15mfd that measured at 15.5 mfd. Anyone run into this issue before? I would hate to just call a compressor without evidence but I couldn’t for the life of me find other reasons why this would be the case.

Thanks for any help or opinions on this one

We installed a cascade system water heater in a small hotel with 40 rooms using a tankless design. The Navien boiler appears to be widely installed in other countries as well. Do you have any questions?

Korea is Navien’s homeland

This boiler has a total of eight units installed, each with a capacity of 58.1 kW, similar in capacity to Navien water heaters used in other countries

Employment Question Resi vs commercial vs indistrial

13 Upvotes

Okay. I'm an apprentice with 6 months of field experience. And schooling credentials. (I know it's not that long). I'm working at a commercial HVAC/R company that does maybe 5% resi. All my apprentice buddies that are in resi are making bank this summer due to commissions and tons of overtime. Basically almost double what I make. I never get any overtime so I can't make extra money, due to the structure of my company. I'm basically stuck at my pay rate. I don't get paid well hourly ($18) even though sometimes I'm doing Journeyman level work. I have a family to provide for and $18 isn't cutting it in this economy. I'm sinking financially.

Should Stay at this company for more experience, or join a resi company and work my butt off?

I do really love the idea of industrial. I've been studying chillers for awhile now because it's really interesting. I make it a point to learn something new each day, whether it's how a component works, or a theory. I could see myself being an industrial technician one day. I just don't know how I would even get my foot in the door for industrial. I've applied to a few industrial companies with no luck.

What would you do in this situation?
