Smoke out of A/C vents

[Olin]

I agree with shadrach, it has happened to mine once, same thing, wet cold morning, fired it up and a condensation type vapor, streamed out for a short time (no more than a minute) then it was fine. With yours having no odour it sounds more like the cold air vapour, just the atmospheric condition at the time.

You will obviously keep an eye on it anyway, but hopefully all should be good.
