The term for the situation when warm air enters home from the foundation vents, gets trapped and rises through the hundreds of holes in the floor then proceeds to rise through the home until it leaves out of your attic soffet vents. All the while your AC is working hard to cool this constant flow of air.
SHUTTING DOWN where warm air enters the home drastically reduces the load on the AC thereby reducing energy cost by 16%-24% in the home. While also creating much drier cooler “crispier” air.
50% of a home’s air, with foundation vents, comes from their crawl space.
This air passes over the moldy plasticThen passes by the moist moldy beams
Through the moldy critter infested insulation
Then passes through your floor: if its a wood floor … eventually cupping the floor
Sealing the foundation vents
stops warm humid air from entering the home. So it no longer passes by the mold made in this humid environment and then travels into the home thereby GREATLY ELEVATING the homes quality of air.
