Leaky pipe, leaky roof, humidity issue, etc...

At what humidity level does sheetrock/drywall and other porous material become susceptible to mold?

We just don’t have the high humid temps or very low temps that would make climate control super desireable.

Put your thermostat on hold 70 degrees or higher.To help minimize temperature loss you can boil water, make soup, or stews; they help introduce humidity and warmer temperatures into your home.

More soffits to improve ventilation and thus decrease possible build-up of humidity in the attic is generally recommended.

@Ryan Redenius that problems stems from high indoor humidity and cold glass surface.

.), broken down into subcategories, you can maybe see that exterior renovations generally cost more than kitchen/bathrooms etc for the majority of properties in that area...Then you could start to come to more educated conclusions of maybe what material to use for a deck foundation because it turns out the extreme humidity wears out certain materials faster than others, and who you should hire to do the work based on a calculated average of cost vs. positive reviews for each contractor..This is a pretty simple and limited example, but I guess my point here is that data and ML will absolutely help you identify certain trends with more precise accuracy, however it still requires a thinking brain to figure out why that trend exists, what direction that trend is going to go, and execute a plan based around your newfound insights.

Humid, warm air inside the unit condensates against exterior walls or windows where it's colder.

I investigated, tested humidity and moisture and found no problem.

Supposedly it helps cars from rusting too somehow - humidity or something - I dunno.
