blue tape and some paper will suffice for short term to close off return vents.

I guess I don't understand this. I, like Jeff, have two units, upstairs and down. Each unit has one return air duct, which is where the filters are installed. If I block off the where the upstairs system sucks in air, am I not basically making it difficult for the system to breathe? That seems like a guaranteed way to make the unit fail quickly.
