I just bought one of these unit heaters secondhand. It has electronic spark ignition, not a standing pilot, so the wiring might not match 100%. But this is how mine is wired (and it works). 40 years old and indestructible 👍 The thermostat connects to terminals on my heater's pilot control...

I do have a portable recovery machine and a shiny new Vevor cylinder. There is a filter-drier but no oil separator. I think this means I need to run it on slow mode and extract the gas only. Haven't had occasion to use it yet. I'm assuming that if I had an oil separator attached to this...

The line was fixed, the system was recharged, and it's running fine now. "fine" It would be unfortunate if it only lasted a 1-2 summers due to low oil. Also unfortunate if I overfilled the oil tomorrow and that wrecked it. Not sure which course of action is least risky but I'm leaning toward...

So that would involve recovering the refrigerant, opening the condenser unit, cutting/de-brazing the internal connections, and voiding the warranty. Right? What would a professional HVAC tech do in this situation?

So, the lingering mist in the air after venting was mostly oil? Suffocation aside, have people actually been harmed by it? How is this normally done? I wasn't able to find any instructions for a minisplit that did not involve invasive disassembly procedures. Seems like it's a common...

It's FV50S PVE oil, so the MSDS is https://www.nu-calgon.com/media/8953/4319-20_sds_eng_20221207.pdf No symptoms. But the mist was everywhere. Saw it in my yard and crawlspace cams. I'd like to better understand whether the mist was just refrigerant and water vapor, or if there was a lot of...

During the installation of a 2.5 ton R-410a multisplit unit, approximately 7 pounds of refrigerant were inadvertently vented outdoors due to a DIY installation mistake. The location where the cut happened did have visible PVE oil residue. The entire yard was filled with mist for about 20...

Huh. Searching around the web for [techbrite surface wrap] brought me right back to GJ: https://www.garagejournal.com/forum/threads/surface-mount-led-fixture-replaceable-tubes-with-cover.507386/ Thinking of pulling the trigger on this one...

Which brands/models would you recommend? Do you know of anything that is available in a wraparound style?

You're using the Maxlites? Or something else?

After perusing the Best Light Fixture sticky post, I started looking around for new 4 foot hardwired T8 fixtures. So far the results have been underwhelming: The Maxlite fixture in the sticky post takes single-ended bulbs. I see posts here suggesting that double-ended fixtures are better (and...

You're saying to test at 7-8" WC = ~0.25 PSI, but with air rather than gas?

Can't have a union in a concealed area. Also the whole point of buying the MegaPress jaws (which weren't cheap) was so that I could avoid the messy and time-consuming process of cutting threads.

I have a press tool with IPS jaws. I've previously done water plumbing with ProPress. I've never used it for gas before; all of my prior gas work has been threaded. I would like to tap into an existing gas line which sits behind a garage drywall ceiling. I believe that the easiest way to do...

I rerouted an indoor gas line a few months back. Called the gas utility over to inspect and he said it looked fine. I asked him about running a pressure test and he said that in his experience, that's a bad idea on an older home. The elevated pressure could blow out old thread sealant and...
