Do we have any HVAC folks in the house? After sealing up my house, I now have an excess humidity issue, and I understand an HRV or ERV could help, along with some fresh air, which would be nice. My current fresh air valve only opens when the furnace is pumping heat, so useless in the summer, and only gets drawn on passivly. I'm a but confused as to what I'd want, but it seems like ERV's are the better choice? I've been looking at the Lifebreath with auto balancing, and it looks simple enough I could install it myself, but they don't really offer support for that.
