I've had cars that have blown out a lot of moist air when starting up but only for a few seconds and that was always on a hot day after the a/c had been used and turned off.

If it was me I'd have the heater matrix checked, but I'm no expert.

 

could very well be the heater matrix. have a check around the passenger footwell to see if it is damp. If it is the matrix then I believe it is a very fiddly job to replace.
