Solve the humidity

I don’t guess who to call but there is a big problem in our new house.

It is so humid in here that the wallpaper is literally peeling off of the walls.

I guess where the humidity is coming from, it is coming from the washer & dryer. The laundry room has a door but the door is not sealed. Infact, it has a more than one inch gap under it as all of the doors in the condo do. I think this is so that the Heating, Ventilation, & A/C system will work properly even with the doors closed. Yet, if the Heating, Ventilation, & A/C system was working properly, the condo should not be this humid, however so who do I call? Do I call a plumber to find out why my washer is making so much humidity? Or should I call an appliance repair woman to look at both the washer & dryer? Maybe I should call someone to just come out & change the door to the laundry room so that the humidity will be contained in there & not spread all over the house. Perhaps I should call out an Heating, Ventilation, & A/C serviceman to take a look at the a/c & find out why it is not removing the humidity love it should. I think an Heating, Ventilation, & A/C serviceman might also be able to install a whole-home dehumidifier too. That might help. I already tried a portable dehumidifier. It works although I have to empty it every few hours or it will stop working. I am just not sure what to do or who to call. I might just have to call out all of those workers I mentioned & have them come out at the same time to sort it all out for me.
