The author doesn't mention brands but I found that the majority of the cost difference was due to it. I got two Daikin installed and it costed me 15k$ CAD. Simiilar models in Chinese brands run at half that price. Mine also run at 100% efficiency at -15C where most just run 100% at -5C. If you want -25C ones they become much more expansive though. I got quotes from 4 vendors. None were technical enough for my liking they all just told bullshit marketing stuff. One tech did a better job and convinced me, but I still think like the author that they don't really understand the science behind all of it. But this is nof the only industry, I DIY renovated my whole house and I can tell you everything is over the top these days. Another quick example is electricians still wire light circuits like in the incandescent days (max 8-12 bulbs per circuit) where bow LED consumme a fraction of it.

If you’re talking about residential wiring, most electricians will (in my opinion) correctly wire rooms to breakers rather than device types. It is infuriating to discover that every light on a story is on the same circuit when you want to replace a fixture at night. For dedicated lighting circuits in the USA, the good news is that the 2023 NEC has provisions for 10 amp / 16 gauge circuits in recognition of efficient LED lighting.

  I think the reason lights are on a separate circuit is that you don't want the lights to go out when a circuit breaker trips. That may be in the code, but I'm not sure.

  Boy, how I wish my breakers were that nicely organized. They’re, at best, regions of my house. Every time I need to do some electrical work it’s a complete guessing game.

    It's worth taking the time to flip the breakers one at a time, then go around and test outlets so you can write the information down. Good activity for a slow weekend afternoon when you're not under time pressure for another project, and while it's daylight and not unbearably hot or cold. :-)

The last example may be code, not sure the code allows you to put 50 lights on the same circuit. At least not cans that could hold a normal light bulb. Perhaps wafer lights can get around that as they are fixed load.

If you're planning ahead for LED light, IMO it's generally better to get a dedicated power supply and wire up DC LEDs, as they're much longer lasting than retrofit bulbs. You save on wiring, too, without any safety risk of someone filling the circuit with incandescents.
