grant said:I know years ago we had to install exhaust fans in the laundry to meed FHA lending requirements. It really had nothing to do the the NEC. In our area most laundrys have exhaust fans since no one likes leaving a window open during the winter.

grant said:The same place the air comes from that lets your fireplace and the burners on your stove burn, and allows you to inhale. If you find a place that air tight let me know what kind of seal they have at the bottom of the exterior doors, I could use some.

That minimizes air infiltration and reduces the intake of unconditioned air when doors are opened, etc. I've asked more than one HVAC guy why we don't do the same thing in homes. They've all said it was a great idea, but nobody does it.
It seems that, with all of the air exhaust systems (bath and kitchen fans, furnaces and chimneys, clothes dryers, etc.), it would be better to have fresh air mixed with the return air and conditioned, than leak in around doors and windows.

That's not really new. It's called an air-to-air heat exchanger.c2500 said:Trane has a neat system that transfer the heat/coolness to the fresh air and minimizes the heat/cool transfer to the outside.
