Please Help Me Identify this Odd Household Sound

I would like to thank everyone who responded with suggestions to try an help. After some experimentation, it seems it is likely the steel AC duct expanding and contracting. There is a huge temperature differential as it runs below my room, as the uncooled garage is below my room. Turning off the AC removed the sound. Turning it back on brought it back.

Or it could be a cold cricket.

Or maybe Death is too cold…

Hey! Where’s my ‘atta boy Chris’? Huh?

I nailed it.

More important still, when should I expect the naked pictures to show up (You don’t think my advice is free, do you?).

*For all the prudes out there, of course I’m kidding. I only want one picture.

Atta boy, Chris! :smiley:

I suppose I can settle for that.

Glad you got it resolved.
