She is keeping the mini-split set at 70 usually and sometimes 68. I am getting a humidity monitor and room thermometer to test the what the actual temp. and humidity is in the room. But you are on the same page as my evaluation. I am just uncertain what to do to solve the problem.

My issue:  Wood sub-floor suddenly staying wet with between 17%-24% moisture and the old peel and stick floor tile has come unglued. Cant lay new tile until sudden moisture problem is solved. This is the first time we have had any sub-floor moisture problems in this home we have lived in since '73.

House description:  1945 block and beam, 835 sq.ft., walls and floor not insulated, minimal bat insulation in ceiling, attic has large gable vents and two whirly bird vents with closed non-vented soffits.

Recent changes:   6 mil. poly sheet on crawlspace ground well ventilated and moisture free.  Added 1-1/5 ton ductless heat pump/ air conditioning to the room that is having the issue and using the ductless unit as the main cooling for the house with one window unit used occasionaly to help circulate the air. Two weeks ago we set up a 70 pt. per 24 hr. dehumidifier in the room with the ductless and wet sub-floor. The dehumidifier has ran at full capacity the entire time. And I recently added two L walls in the attic to add support to this old 7/12 pitch roof.

I have done a lot of research and I have my personal evaluation but this old woman will not believe me. She seems to wish to believe product review websites and whatever she can find on the internet to my hard work researching building science. Please advise.
