What was that noise?

[JAMAS]

Squirrel cage (hvac fan) throwing a blade?

the fan was off....although my vents were set to let outside air in.

if that did happen, is there anything to be concerned about?

Doubtful that was it if the fan was off, but if it did toss a blade, it would be out of balance & probably make noise.
Never seen it happen, just a WAG.

Thanks. I am sure it was just another VX creak or noise(I hope). Kinda like an old house. It could be haunted too.
