Running 2x, 22awg cl2 hdmi's though a furnace room ceiling and I was wondering what kind of spacing I should keep with the air ducts/power/phone etc that is in there? None of the ac lines are in conduits either. Thanks

I don't have a definitive answer to your question, but in the absence of any other replies, here's a few miscellaneous thoughts: IIRC there should be a minimum of 18" separation between power lines and analog cables (like speaker wires) + for high-speed network cables you need to be >12" from mains wiring. What I'm unsure about is that as the HDMI is digital. does this make a difference? - I guess that interference could/would manifest itself as sparkles and/or maybe loss of sync. I'd try to attain maximum separation from power lines and try to avoid parallel runs if the gap gets tight - if you do need to cross over a 110v cable, do it at right angles.

The telephone wiring isn't really a problem - it's typically a spikey signal but is at a low voltage. Proximity to the air ducting isn't a concern at all.

Generally speaking, that is correct. Just try to keep all the low voltage wires a foot or so from the high voltage. Nothing else should present itself as an issue. Duct work is also a non issue from all I have heard. The low voltage wires generally do not need any separation from each other, so HDMI, cat-6/5, phone, etc. can all be run side by side without issue.
