drywalling my basement
Use a box fan (blowing out) with a furnace filter in front (to save the motor and neighbors) in a basement window for a negative air pressure down there. Cardboard around it to air-seal. Crack open some various upstairs windows for make-up supply air flow.
P.S. Hope you air-sealed all holes through basement ceiling from wiring/plumbing.....
Clothes taking longer to dry?
Clean the dryer screen in HOT water if using fabric softener sheets.
They leave a residue that impedes air-flow, costing you money.
Clean the ducting in the last six months? 17,000 dryer fires annually!
