Those reports look pretty good compared to some I've seen. Duct system seems to be sealed pretty well, could be better but not bad. The house could use some improvement as well but overall not bad compared to lots of homes I have tested. I would definitely look into the iq drive, especially if you can get a discount through your son. It is a really good system. I was skeptical before I installed one. The two customers we have installed them for love them and the savings on utilities but the main thing they love is the comfort they have now throughout their home.
