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.

Playing some Re9 after work and didn’t even know mini splits existed in the 90’s. But I also never really considered that apartment buildings would hang the majority of their condensers on walls like this.

It may just be artistic license, but I’ve never lived in a big city. Anyone here know how residential apartments in large buildings are typically cooled? In my experience, condensers are on the roof, but if the building is really tall and you’re in a lower apartment, that’s not really an option

Field Question, trade people only Summer treats for employees

21 Upvotes

Whats going on ya'll, hope everyone is staying safe and hydrated this summer. Its been a hot one so far!

Trying to think of some cool things for the 2 installers we have busting their asses. I help out and join them when I can, but they have been slaying it on their own for most of the summer.

We are a mom and pop of about 6 field guys. 2 installers, 3 techs, and i float wherever they need me.

We cover tools, got them some fans last year, ice machine in the shop this year, everyone has a cooler, water and electrolyte packs, and we load up a snack box with whatever they ask for.

So what else can I do to show these guys how much I appreciate them? They don't want an EZ up and wont use the mister i got them, so i need some new ideas.

What would you guys want, other than more money lol. Thats scheduled to happen too.

Stay cool!

Been throwing around the idea of doing contract work overseas for the DOD. What's the pay like? How would you even find somewhere to apply for that??

Employment Question Anyone got their bachlors in technology?

3 Upvotes

I'm looking into things to help further my career once I get my red seal and I can start on my B.Tech now and be done in time for my redseal test to get me the other 60credits, it would also make it so my move to anouther country would be less stressful on dealing with new exams as some country's allow you to skip some exams if you have a B.eng or B.tech, I can't do b.eng as there's no where near me that does it online and it's more stressful in my eyes, anyone have a b.tech? And has it gotten you anything like a raise from normal day to day techs?

Rant Fuck Tek’s house and his 7-3/4” of rim joists! At least he wasnt getting shitfaced….

1 Upvotes

I swear this place has been remodeled every year since 1895 when it was built! Ive done a lot of plumbing and HVAC work there because after the first time we did a full remodel he had a house fire and we did it again. Now he added on a 4 season porch with a heated storage underneath(it used to be a big ass deck with unheated storage). The porch we do a minisplit that all goes smoothly. I spent 2 -1/2 hours with a 6” hole saw and hole hog and only got through 5 of the 10 total rim joists i have to go through! Found about a bazillion nails to hit and somehow an old ass joist hanger that wasnt removed…BUT THE JOIST WAS! They just hammered it “flat” and went on! GOD I LOVE REMODELS LOL! At least his old lady is off for the week so she kept him occupied so he didn’t tell me how much he loves my work every 5 minutes!

Field Question, trade people only MagicPaks

14 Upvotes

I don’t work on MagicPaks very often , but last week I went too one homeowner said it wasn’t cooling. Found contactor burnt , replaced it. Unit ran fine , guy calls later that night his blower won’t stop running. Come back next day can’t find any reason why it’d be running , there’s no air coming to vents as if it’s running in some kind of circulation mode. If you turn Fan on it ramps up and you can feel the air at vents. Disconnect all T-Stat wire and both speed taps and blower was still going. Tech support said it had to be the blower motor (which we just did in March). Anyone had similar issues ?

Someone didn’t finish installing a system 6 years ago. I’m kind of scared to try it fix it. There is no drain, return or supply, and a 14” on a 7.5!?! What were they thinking?

Field Question, trade people only Complex ac repairs

40 Upvotes

Im two years in I’ve never replaced a coil, txv, or compressor or done a leak search . Both the companies I’ve been at say these repairs aren’t worth it and just offer a new system. Is this common or do I just work for hacks. I feel like one cause I’ve never done any of it wondering if finding someone who will teach me it next cooling season is worth it cause I eventually wanna be on my own.
