It condensed all of the information I needed into an easy to understand format and pointed me in the right direction for which materials to use on properties.

It's interesting that the HVAC guy installed 4 separate condensers outside (4 single zones) as opposed to one condenser (one quad-zone) with 4 air-handlers.

Would this arrangement not trap any moisture escaping from the conditioned space, or condensation that occurs between the floor and poly, and hold it in the batts?

The condition of property is good, with new updates in the last couple of years such as; roof, hot water heater, inside ac units in all four unit with two new outside ac condensers and new electrical panels with breakers.

The information I've found here is the point of every book I've read so far in a condensed, to the point format.

I already had a condensation pump, so the water that the furnace produces isn't a problem.The problem will be in a rental house or flip, especially if there's no basement.

I walked through a couple REOs today with a buddy and one of them had a good amount of copper stripped from the garage (hole in drywall) leading to the condenser outside.

There is a cronic problem with mold in the house that is believed to be sourced from the condensation between the slab and the home when it is occupied in the winter time.

This is highly condensed.

Is too much air escaping through the ceiling in winter and causing condensation (think mold again) to form underneath the roof.
