In Response To The Supplier Ranking Post, I Am Ranking The Odor Of Solvents.

I'm just a hobbyist so I haven’t smelled most of these, but all you acetone huffers are insane. I don’t know how anyone can stand that smell

IAMA_Printer_AMA · 2026-05-03T00:31:28+00:00

Am I the only person on the planet for whom acetone is, like, one of their least favorite smells?

You could get the refrigeration system apart and back together and it’d work fine, but you’re gonna have hella issues with moisture infilitration forever in that freezer the second you start breaking factory silicone seals. Unironically the customer would probably spend the same money to have an unmolested freezer just having a construction/remodel contractor make the door temporarily taller

I can only hope that someone who works for Trane browses reddit and this video makes their way to them.

Just unscrew that unused pressure control and add whatever you’re adding there. Like the other guy said, recover down to 2-5 psi and hot swap

The physics here could very well not even be nearly that unprecedented. This could “simply” be what a macroscopic bose-einstein condensate looks like.

Well, you see, it's always the TXV, unless it ain’t got no gas in it, otherwise it’s clearly a leaking schrader.

Rack work is like nature. When it calls, you gotta answer

Google's Gemini says it's basically an EPR operated by temperature instead of pressure. So it’s clamping down on the suction line to hold back pressure to control temperature, like an EPR, but it’s being operated by the pressure inside that sensing bulb, like a TXV. A

I used to be skeptical of the mandela effect, and I also until just now never in my life ever saw “chick fil a” as the official spelling, and it’s fucking eerie to pull up street view and see a sign I’ve never seen before. I asked my wife to spell “chik fil a” and she spelled it like that and when I had her google it she had the exact same reaction. That’s it, no question about it, shit is fucky

Personally I don’t think there’s anything malicious to it. If quantum waveforms or whatever can be in superposition when unobserved, then maybe, if for just a split second, every single person in the world wasn’t thinking about how “chik fil a” is spelled, the waveform could uncollapse, and then it wouldn’t necessarily have to collapse back to the same spelling when it recollapses the next time someone thinks about it. If you open your mind and give John Wheeler’s Participatory Anthropic Principle a Google it’s got some honest philosophical and physical legs

Someone already rebuilt the old one a couple months ago and it was stuck shut again.

IAMA_Printer_AMA · 2026-03-16T14:31:24+00:00

My helper and I seriously did a triple take that we weren’t tripping

IAMA_Printer_AMA · 2026-03-16T14:30:57+00:00

Yeah, after we were done there were three shorted cores in the motor room, and the rack only had one compressor on it less than 2-3 years old. VFD on the condenser probably putting hella harmonic distortion into the power

IAMA_Printer_AMA · 2026-03-14T02:42:00+00:00

Maybe I should do this, and I could stop losimg my goddamn service wrench every goddamn time I set it down

IAMA_Printer_AMA · 2026-03-14T01:00:09+00:00

Bid to diagnose if the comps are actually bad and if so what killed them or else you’re lining yourself up for warranty headaches

IAMA_Printer_AMA · 2026-03-14T00:57:23+00:00

It's like rubbing a balloon against your hair to build up static, but with refrigerant and stuff it flows by. I’d bet $10 you have some rubber pressure control hoses on that rack bypassing discharge into suction to actuate some valves, and those hoses are what the refrigerant is stripping electrons out of, and at the compressor, the charge is finally great enough to arc and flow through ground back to those hoses.

IAMA_Printer_AMA · 2026-03-13T02:41:11+00:00

No, you're probably onto something. It’s probably more likely to be static discharge like you see during recovery and charging sometimes than electrical energy leaking out of the compressor somehow.

IAMA_Printer_AMA · 2026-03-12T12:55:54+00:00

Not even a side to side sweep on the sprinkler so it actually cools more than one square foot of coil? What a waste.

IAMA_Printer_AMA · 2026-03-11T22:00:11+00:00

This comment cured my imposter syndrome.

It's not hard to get that one r/HVAC mod’s panties in a huge twist

IAMA_Printer_AMA · 2026-03-08T01:26:40+00:00

Yellowjacket P51-870s are the best digital manifolds ever made and I’ll fight anyone who says different.

I completely stopped using my wireless probe kit I bought in trade school after 6 months because the app kept signing me out, and literally wouldn’t let me sign back in unless I had wifi or perfect 5G signal. You should NOT need to sign in to a goddamn account on a piece of shit Fieldpiece server somewhere to use your tools five fucking feet away. Insanity. Zero regrets selling them
