So this is ultimately a very oddball situation. Some background:
I live in a rancher in southern NJ. Fully electrified home.
I had recently installed minisplits to replace some electric baseboard heaters, covering about 2/3 of my home. This was fortunate, as I believe my blower fan in my central AC unit blew out. The minisplits + 1 window unit have actually been cheaper to operate than the old AC unit, so now I have a vestiegal high-velocity central AC system in my attic.
Namely, this means a lot of unused flexible, insulated ductwork and some ferro-fluids in my attic that should probably be blocked off and drained, respectively.
I've been contemplating on how to possibly repurpose some of this stuff to fix one of the biggest blind spots in my home: ventilation and filtering
My one bathroom exhaust fan vents directly into the attic, which is a moisture hell that needs solved.
There's no other ductwork in my home, and pretty much the only time fresh air gets in the house is if we crack windows or open doors.
So the theory is:
I route the bathroom exhausts into the old air handler coils to help capture the moisture and drain it out, then have it mix with some outside air and recirculate it into the house again.
Alternatively, routing some of the air between the attic/crawlspace/attached garage for preconditioning outside air as as well.
Is this insanity, or a remotely plausible idea? I'm fairly handy, and since its sbeing made with vestigial bits in spare time labor cost is much less of an issue than parts.
