I'm sorry for the delay, work got the best of me then hand an emergency trip.
few updates for you.
1) photos - all the photos i took of the process are here, the first ones are the before, then i would jump to the end for the finished ones.https://www.dropbox.com/sc/pendo3o2tfcn3ut/AABte_dFfWpoDTuTODinMYMVa
2) Humidity - you were right, the despite the humidifier on the furnace, we were sitting around 20%.
I guess it was mostly due to warmer weather so the furnace was not on enough hours.
As a temporary fix and with good timing, I boiled my maple sap in the house this year, that put about 20 gallons of water into the house over 2 days and kept the humidity at 50-70, that was about a week ago, now its down to upper 30's, but with warmer weather coming it should come up.
I spoke to the local HVAC company and I have ordered a Lennox 220v Humidifier. This is a separate unit that can turn on the fan without the heat, and blows steam directly into the plenum.
Thank you for your advice and help.
