I've been hunting some air conditioning information, and thought I'd put together some samples to look at.

Air Conditioner signals are typically very long because they encode all the settings in each signal (ie, fan speed, on/off, temp, etc) as this allows them to give you a visual readout on the remote without really having a bi-directional signal between the A/C and the remote. So this is a case where you often need an IR Widget (or something similar) to capture the full signal.

I have created a spreadsheet containing a complete breakdown of the 3 complex A/C signals that we've documented so far.

It's a bit disappointing to see how many of the threads above end up incomplete because the OP never followed up.
