General State of the Subreddit 3/31/26

74 Upvotes

Good evening,

I would first like to thank everyone that has already completed the new verification quiz, we've already gotten loads of approved users! (For the second question the answer is "It Depends", my testing was apparently not thorough for spell checking and mobile compatibility). That verification fix will be released once Reddit approves the update.

It has come to my attention that a former mod went a little rough with certain permanent bans that were issued. If you happened to of been caught in the crossfire please feel free to open up a unban request in mod mail. I've already unbanned multiple people.

The actions from that moderator were inexcusable and I deeply apologize that we provided such a disservice to this community.

Please let us know what else you would like to see improved in this sub.

Thank you,

r/hvac Moderation

Edit: Looks like reddit is mad at the approved user count, the verification requirement has been disabled for now.

Edit2: It's back again, I've sent in a message to reddit staff.

What's your response in situations like this.

I did install the run, honestly those holes kind of slipped my mind and I probably could have hit it with tape or caulk but..

"After some googling it seems the installers didn't do this right"

Cmon man.

General EPA 608 Certification, what’s respected ?

3 Upvotes

I’ve been studying through SkillCat and I think I’m retaining the info really well . It’s a great program and I like the way it teaches. Is the SKILLCAT EPA 608 certification respected at supply stores ? Like Johnstone, United refrigeration, Trane ?

I found a 2017 for 15k. I really don’t know how they hold up as I’ve only had fords and Chevys. I do a ton of highway driving. Will it make a good service truck and why would they get rid off it?

General Homeowner installed his own furnace

Well this is one of those the more you look the worse it gets situations. Old man said his nephew put in this "new" furnace for him, just about everthing i can name is wrong. Gas, ductwork, electric, what is the point in bringing in outside makeup air with loovered doors. Refrigeration is so messed up, 50/50 on every joint completely kinked lines it's all just a big mess. But most of all the flu, bro said "it needs a trap doesn't it? " just straight up blowing fumes into this old man's house. Literally gas chambered this poor guy, and he didn't have any drains on this thing at all!! Maybe that's why he thought he needed a trap i guess. I got it to run where its safe but will be back to overhaul everthing hopefully soon. It's ugly but functional for now lucky for him i keep lots of old crap in the shop. And the supplies are wierd 1 6in pipe supplying 4 registers that are reduced to I think 5 in, redoing it anyways but. HOMEOWNERS DONT DIY AN INSTALL IT'S NOT WORTH YOUR LIFE.

Field Question, trade people only Should I buy a set of probes fresh out of school?

1 Upvotes

Really close to graduating with an associates degree from the local community college. I am part of a scholarship program that gave me a decent amount of money to spend on tools. Obviously I am getting all the hand tools I need and was wondering if it would be smart to buy the fieldpiece probes/temp clamps/psychrometer set? My doubt lies in if this may be something that my future employer may provide down the line or maybe I don’t even need them yet as I don’t exactly know if I start right out in install. But seems like a good investment no doubt. Hope everyone is doing most excellent out there and thanks for your time!

General Testo tools consumables

1 Upvotes

Anyone happen to know where to get spare consumable parts for probes? I have some testo refrigerant probes and a micron probe/guage. My depressor on the micron probe broke and I tried emailing testo and they insisted on sending my probe out for warranty and I don't need the whole tool replaced. I literally only need the center depressor that is replaceable. Just wondering if anyone else has had any luck. Local supply store sells tools but not the depressor or the plastic seal piece for the refrigerant probes and I didn't see on their website about any of those being sold separately. The probe was free when I got a vacuum pump. I have a spare yellow jacket micron gauge that I use currently, but it would be nice if I could use the free tool I got.

Field Question, trade people only I dont use MR Pex manifolds, only experience is one install and one replacement. Is this repairable?

Post image
1 Upvotes

I had forgotten to close this valve when i went to fill up again on a combi swap out. All of a suddenly the valve stem falls out and starts pissing. I had “opened” it a bit to drain but also opened the pressure relief valve. The supply manifold valve closed again. By looks its not necessarily repairable. If you’re experienced with mr pex manifolds let me know. Im full prepared to replace manifolds anyways because to repipe the previous companies shit work its probably easier to replace both of them.

Field Question, trade people only How much do you think you spent “investing” in yourself?

11 Upvotes

I’m the guy who gets cheap buying random things I need like dress shoes or tennis shoes, but also won’t hesitate to spend $300 on new work boots instead of buying a cheaper brand. I also have my tool brand loyalty and wont hesitate to pay a little extra for the same tool that is cheaper from a different brand. I know not everyone is like me and of course you can be a good tech still and not spend extra for certain things. Whatever, I like what I like and accepted this fact about myself already. When I started in the trades I showed up my first day with a plastic bag with a borrowed hammer and two screwdrivers in it cause that’s all I had. So anytime I buy a tool or something for work to me it’s an investment more than a random purchase.

It got me to think, how much money do other techs spend on tools and equipment they need/use/want for their work? Just this month alone I bought new boots for $300, a veto tool bag for $250, cordless shop vac and batteries for $200 and those are all things I didn’t really need right away to do my job just things I wanted that I can use for work. That’s not even counting all my power tools and batteries I have, tool boxes/bags, countless hand tools, work wear and other things I already own. Plus I had all my
Tools stolen out of work truck a couples years back and had to re buy everything again which sucked but I learned my lesson and really value and take care of the shit I had.

I’m about 4 yrs in the trade and I am an installer so I do have more tools needed than prob a service or maintenance tech would need day to day. But u estimate in total I have prob spent $7-10k all together. Curious about how long someone’s been working, their role and how much they think they have spent all together since becoming a hvac tech.

After being hesitant and just out right too cheap to buy the veto pro pac tool bag I been wanting. I got a little buzzed after work on a Friday and did a little splurging lol.

TBH the thing that really made me say “fuck it” was seeing the brand new hire straight out of trade school walk in on his first day carrying the exact tool bag I been wanting. Lol

First time visit for a humidifier and furnace. Their usual company was booked out and we had openings.

Needless to say the drain for the humidifier was clogged. Quoted adding a pvc line and drop tube for the humidifier, but they declined.

Employment Question Think of leaving the union and going back to nonunion. Would I be making a big mistake?

13 Upvotes

SoCal (San Diego) area. 1st year apprentice as a DDC tech and I don’t think I can stick it out. I came from trade school a couple years ago and worked non union in controls, then found a union contractor that was hiring. I don’t want to go into much detail but where I’m at has been taking a real toll on my mental health to the point I don’t even want to wake up some days. It doesn’t help that my students and teachers tell me my employment is 70% politics and if I’m out of a job depending on who hired or fired me I can easily be blacklisted by word of mouth to other contractors. Would I be making a big mistake if I left? Would my BAS give me an edge on finding another job quickly (I have about 10 other certifications that I’ve obtained over the years too). I’m worried if I leave it’ll hurt my reputation and career. Also with this job I have a sign on bonus I would need to reimburse if I left. Any advice?

General A question for my fellow EU techs

2 Upvotes

How do you guys feel about the EUs f gas regulations and restrictions that are going to get harsher as of 2027 and 2029 and onward?

Is anyone else concerned about the fact these restrictions seem way to aggressive and in some cases feel like they're designed without much thought or insight from the industry?

And I've heard rumors R454C will most likely be introduced to cover a majority of things R32 did when the bans come into effect.

Anyone have any thoughts?
