General State of the Subreddit 3/31/26

73 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.

Employment Question Looking for something different..

8 Upvotes

I’m not sure what it is, but my heart just isn’t in it anymore. And it’s not like I’m being ran ragged, I work on 90% centrifugal chillers and 10% of the other stuff but I’m just over the customers, the on call, and the emergencies/OT. When working on package units and performing project work, I find to enjoy my days much more. Debating on getting out of the chiller team and into the air side team or leave service altogether and go back to my roots of doing commercial HVAC construction and retrofits.

Anyone else get into these funks and do anything about it? Or do you just keep on keepin’ on?

4 year old system. Last guy wrote up compressor. We swapped it out. Still sounding like a gun shot when it shuts off.

Job was relocating this gree condenser off the floor and onto the wall. Everything was done, vacuum, comm wires, king valves cracked, etc, i was just waiting for the electrician to extend their whip. Went yesterday to start it up and close out the call, and I was greeted with this immaculate job. Roofers cut the zip ties, ripped the v-bats off brick, and threw the Lineset over the condenser stand lmao

Employment Question Am I underpaid?

36 Upvotes

I’ve been a residential HVAC service tech for just over three years and I was an apprentice before that. I’ve been with the same company my entire career. We are based out of North Florida. I’m not really familiar with what techs are being paid or what a tech should make. based off talking to other guys in the parts houses with similar experience it just seems like everyone else is making more money than me. I do phenomenal on every performance report, kept recalls down etc. But still make between 20-25 an hour

I’m not saying I should be paid more than that it’s just I have no idea what the market looks like when it comes to pay for technicians with my experience. So I’m just curious to see what the vets think about it.

(EDIT) thank you all for the feedback! Very helpful and informative. Yall stay safe and get some.

Tell me what you think of my controller retrofit install. Give me your opinions.

Edit: I’m a 1st year, this is one of the 25 controllers I’m doing for this retrofit. They all have essentially the same layout as this one.

Field Question, trade people only Older Branch provider Unit question.

3 Upvotes

And by older I mean 10 years old. To give whoever is reading this who might be able to help me the long and short of it.

Outdoor Inverter model: RMXS48LVJU
Branch Provider Unit Model: BPMKS048A2U
Indoor FCU Model: FTXS24LVJU

Been chasing my tail on this for a week now.

I’m getting 220 through out. The only drop in anything I can actually find is from the branch provider F1 and F2 terminals that run over to the Inverter. And I’m not getting the inverter to do anything. Even though it does have power as well.

My real question is. At F1/F2. What should I be getting?

Also the indoor FCU (heads) are acting like they’re working but have zero cooling since the outdoors not doing anything.

I’m not familiar enough with all of the inverter mini split stuff yet but I’m trying. Thank you to anyone who’s got an idea.

Field Question, trade people only M18 Recovery Machine, anyone actually try one out yet?

Hey,

Been peeping this thing not so much for the rooftops but more so for emptying units on the ground. I.e. pulled old unit off and ripping charge out in the parking lot. Wondering if anyone actually has used this thing more than a few times and how it holds up. Seems very convenient when we already have plenty of spare batteries, and if the pressure gauges actually hold up then it would be nice to use it like their inflator that you just set and let it run til it auto-stops.

I know they said 10# per 12AH batt, kind of lame, but not really bad for some salvage type work to save the forklift time or power station.

If not this, may consider just using their 1800/3600w power station on a normal recovery setup. Problem is napkin math has that running closer to 60% the battery efficiency though and even four 12’s may cut it close on one big guy.

Field Question, trade people only Psychrometers or just probes?
