To be totally honest, being green to this new tight-ness and the issues that accompanied it, I had no idea about HRVs or ERVs.
My HVAC guy never mentioned it either...would have been nice to have the option during the build. Seems that these systems are better or rather more efficient with having their own trunks than sharing the existing HVAC ones...
I've done a little research since reading your reply Pete and will definitely give it some deep thought.
With everything buttoned up tight, running new duct-work now..
Thanks for the advice!
