My end goal is to be able to control my A/C (a Panasonic unit) from my RPi Zero.
I'm attempting to get the IR Transmitter wired as per Figure 2 here - http://www.raspberry-pi-geek.com/Archive/2015/10/Raspberry-Pi-IR-remote - however have had no success in seeing it lit. However, if I connect the IR LED to GPIO 14 and ground, I see it light up (via my camera). I should note that when I do this, it is permanently illuminated.
Am I doing something wrong? Is the diagram incorrect? I am using a BC547 NPN transistor, and I believe I have the correct resistors.

Do you have the correct wavelength IR LED?

I believe so, a 940nm one.

Panasonic ACs use IB (infra blue) light. A little different than IR but it works so much better. Unfortunately they cost like $5 for one LED and you need to use a JFET to power them.

Would I still be able to see the light from the AC remote in my camera if it's an IB light?

Why won't a MOSFET work?

We need the model number of the Panasonic A/C unit so we can figure out the IR stuff.

That's a good question. I won't have access to check until I'm home and the thread probably would have archived by then.
I did come across the second one, thanks, not the first link - cheers! I have gotten as far as getting the IR receiver to see that my A/C remote is sending signals - which makes me think it is IR and not IB - but then when I try to make a circuit to blast these out, the IR LED doesn't appear to have any power...

You also need to install Gentoo and compile your LED drivers.
