General State of the Subreddit 3/31/26

76 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.

He called me and said the flame was too much outside of the tube, I don't work on many of these but it seems fine? Anyone able to second my thinking of its fine

General Can't ask for a better Monday to burn off a heat exchanger. It's 66⁰ outside, and the black roof in direct sun keeps it at 82⁰ with a cooler wind. =)

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 Looking for help to get into HVAC

• Upvotes

Long story short, I’m trying to help out my best friend, ride or die kind of guy, would help me hide a body kind of guy… he’s in a tough place.
He lost his job, has no degrees or specific skills/certifications, and 5 kids.
I told him I would pay for any classes/certifications he wanted to pursue. I asked him, what do you think realistically you could do as a profession, but just need some classes to get there. After some time to think about it he came back with HVAC.

Information about him.

34 year old male, high school diploma, jobs in customer service. Southern California, specifically Mojave region.

What I’m asking is. Where do we look to go forward? Is there certification classes or even companies you would recommend? What are the next steps.

Customer calls last night and says his expansion tank just blew off the system. I ask for some pics and this is what I see. On the phone he was mentioning something about a spring and I was really confused…then I saw the pic.

Never seen anything like this before.

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

8 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?

Employment Question UA787 vs School Board HVAC

1 Upvotes

I may be choosing between two offers and would appreciate your input!

Option 1: First-year 313A apprentice with UA787. (Competitive and coveted position)
Option 2: Heating Serviceperson with a local school board ($38/hr, excellent job security and consistent hours).

Both offer pensions and benefits. The school board pays more initially and I’d be apprenticed to a G1 (no 313a potential) but the 787 route likely has greater long-term earning potential and trade advancement.

I’m 30, got my G2 last year, and made UA787’s Ready-to-Hire List while working in residential/light commercial HVAC.

Which would you choose and why?

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?

Field Question, trade people only Specialty Hand tools

23 Upvotes

What’s a tool that you’ve collected during your time in HVAC that doesn’t fit a normal service bag for day to day.
For example, I’m getting into chiller work and recently purchased a 4lb mallet and a lady’s foot. Both of those items I don’t normally use. The lady’s foot was one I never knew about so I thought it was a nice addition to my assortment.

So I'm 6'2" with a left knee injury, currently driving a 24 Chevy express. It kills my left knee driving due to the wheel well location. Boss man said he was open to getting me a different vehicle with leg room. You guys got any suggestions? Are the Ford vans any better? Full size or mid size truck a better option?

Rant Nearly 5 years in and don’t have love for it anymore

43 Upvotes

I’m trying but I’ve been doing this for nearly 5 years in residential side from installs to service, I can’t deal with on-calls and picky customers anymore. If I join the union, they may want me to work from apprenticeship again, which will lower my pay in half. Has anyone switched to a different niche? Like industrial? BAS programming? Or maybe something that has way less on call callouts than residential?

Rant Am I slow?

29 Upvotes

4th yr refrigeration apprentice here at a small union shop. I did non-union commercial HVAC for 2yrs up to like 15 ton units before I crossed into refrigeration a year ago.

I direct entered into the union apprenticeship as a 3rd year, last year.

Was the PM bitch for around 9 months before they cut me loose on service a couple months ago.

They trust me enough for solo service on walk-ins, reach-ins, IMs, etc. no supermarket rack calls yet.

Today it took me 3 hours to do the following:
- 1/2hr to job, 1/2hr to next call
- 30min driving to supply house to get a 25mfd run cap, yeah I could’ve combined a 20 & a 5 but the supply house was a 10min drive.
- diagnose failed compressor due to run cap failure and short cycling on internal overload prematurely due to compressor overload failure. Internal overload kept prematurely tripping and compressor was cold.
- old Hoshizaki KM500MAJ series self contained air cooled
- ruled out everything that could stop my compressor from running
- condemned & quoted a head unit due to evap grid separation & compressor failure

Customer wanted to play 50 questions on why I’m opting for a new ice machine head unit, that ate 1/2hr.

Owner says I’m slow but I only started learning refrigeration a year ago, dude doesn’t even let me take the van home. I only had 2yrs of RTU / split system service experience before I joined up.
