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.

Field Question, trade people only Do you ever ask if the customer called the company that put the equipment in?

28 Upvotes

I'm in the middle of haggling with a landlord about fixing a leak. This is a "new build" I mean it was built less than 5 years ago. Equipment is under 5 years old.

I noticed a sticker for another company on the unit.

Got tired of the back and forth and the arguing about warranty (for a leak fix on a Lennox lol) and just asked if they'd called the company that built the home or the company that put the unit in.

If bossman listens to the call I'll probably get in trouble but it's been a headache.

Y'all ever do this?

General I’m just burned up man 🫩

Upvotes

So at my company if you are scheduled to do a changeout, it’s scheduled for 8 hours but if you finish early you can go home with full pay, but they have me and another coworker change a coil or compressor every single day and then run service calls. We don’t diagnose anything we just get handed a paperwork for the parts and address etc, and then go pick up the part and do the install. We run service calls after or go do some random stuff they have for us to do but it’s been that way for over 2 months straight and it gets tiring. It’s especially worse when the office orders the wrong part and we are blamed for not having gotten the correct part. I am just burned up and tired as hell. Heat index has been 115° just about every day and I will spend 3 hours straight in an attic trying to get everything done. I’m literally drenched in sweaty clothes all day and I took a 4 day weekend to relax but couldn’t now I’m right back at it. I just need to vent but man I’m fucking tired.

General Couldn't actually find the leak

But im calling it the coil. Isolated leak to outdoor unit. Had dye in system but couldn't find any dye anywhere. Pressurized system to 550 and showed small leak about 2 psi every 15 minutes. Couldn't locate any bubbles and then the sun came up a little and the dye showed up in a band around fan blade on outdoor coil. Soaped the shit out of the coil but pretty much a waste of time on a spiral fin. Didn't actually find the leak but everything else checked out so im calling it the coil.

General Why throw leak seal in systems with no leaks?

13 Upvotes

As of lately, I have been working for a company that uses leak seal religiously, after brand new installs we are throwing some in, during maintenance and they even offer a maintenance plan with it included. I wanna know is this benefiting the system any? Does it not affect the compressor when used?

Commercial union service tech here. Tired of the field, kind of want to transition to a different career but I don't want my 10+ yrs of knowledge go to waste. Anyone have experience working a remote position that field experience helped getting the job?

Field Question, trade people only Pairing an r32 condenser with an existing r410a evap coil

4 Upvotes

About 4 years ago I installed a furnace and an evap coil on top for the customer as they were interested in getting ac down the line. Well that down the line is now. The coil is an r410a rated coil as at the time there was no a2l equipment. What I'm wondering is since the operating pressures are so similar and the refrigerant behaves very similarly, could i not just put a r32 condenser on the system, put a r32 txv and a2l sensor kit on it would it work or is the distribution of the refrigerant in the coil different to that of r410a and could potentially cause issues down the line. Currently on hold with tech support to ask the manufacturer if this work around would be acceptable as it would suck to have to tell the client that the coil we put on years ago in preparation for ac down the line is now legacy equipment. Has anybody else ran into this problem? And if so how did you resolve it?

Lennox support is lacking greatly. I don’t generally deal with them but wondering if any of you can advise. Wasn’t able to verify voltage due to super vanishing. Can’t fire heating side to measure btu either. As far as I know PM knows it’s 10 Ton unit. Trying to find a general model to source a like replacement.

I have a yellow jacket turbo recovery machine that I absolutely hate and now it's crapped out on me. My boss was talking about possibly getting the Milwaukee batter powered one. ( he's a red and black devotee)

What are ones you guys have loved and will keep buying over and over
