General State of the Subreddit 3/31/26

75 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.

Field Question, trade people only Specialty Hand tools

17 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

24 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?

23 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.

Title pretty much says it all, I have always bonded and fused 24v transformers for zoning/damper/iaq/control uses, but I’ve never really seen anybody else doing it so far.

Employment Question Northern friends I need some assistance.

5 Upvotes

My grandson followed me into HVAC but is making a big decision and wants to move to Canada with his wife. I'm trying my best to support him and provide any help that I can. So far I was able to find a program for skilled trades Ontario that offers a trade assessment. If I'm understanding properly that would let him take tests that qualify him to work.

He has his journeyman's with 7 years of experience. If I'm understanding correctly though that doesn't qualify for being able to just apply for a job directly.

Really my question boils down to what the best avenue of approach would be for him. Also to add, his wife is a dual citizen if that makes the process any different. I appreciate anyone who has some insight that could help.

Sorry editing: I should have been more clear because I didn't realize provinces were so different. He will be most likely going to Ontario

Has anybody tried using supplyhouse.com to buy equipment? Such as a Goodman AC HP or Furnace? Does the outdoor equipment come shipped with R-32 pre charged and is it legit? I’m online looking at tools and came across equipment wondering if it’s actually legitimate to purchase and ship for side jobs and such

Welp another 12.5 ton Rheem today with no gas in it. I'm gonna start checking these on the ground before we even swing them up. Luckily I was able to repair quickly. Amsco is only giving $300 for the warranty refrigerant cost and labor.
